Most Singapore businesses pour time into content that no one is searching for. You write the blog post, publish the service page, wait, and nothing moves, because the words on the page never matched the words people actually type. That gap is expensive: it is budget spent on traffic that was never going to arrive. Keyword research closes it. Done well, it tells you what your customers want, in their words, before you write a single line. This guide shows you how we do it.
What is keyword research?
Keyword research is the process of finding and analysing the words and phrases people type into search engines and AI tools, so you can create content that matches real demand. It tells you what your audience is looking for, how many people search for it, and how hard each term will be to rank for.
Those terms are your keywords. Some people call the exact phrase a user types a “search query” and reserve “keyword” for the target you optimise a page around, and that distinction matters once you start mapping terms to pages. For now, treat keyword research as demand research: you are learning what your market wants before you spend a cent producing anything.
Get it right and everything downstream gets easier. Your content briefs write themselves, your pages answer questions people genuinely ask, and your whole SEO services in Singapore programme points at demand instead of guesswork. Get it wrong and you optimise for phrases nobody searches, or for phrases so competitive you will never rank.
Why keyword research still matters (even in the AI era)
Search behaviour has shifted. People ask ChatGPT for recommendations, read an AI Overview instead of clicking, and phrase queries as full questions. It would be easy to assume keywords no longer matter. The opposite is true.
Every one of those systems still runs on language. An AI Overview is assembled from pages that match the intent behind a query. A chatbot answers using the patterns in the prompt you give it. If you do not know the language your market uses, you cannot show up in a classic blue link or an AI answer.
Keyword research connects demand to the content you produce, and content to revenue. Choosing the right keywords for SEO gives you three things: visibility for terms people search, qualified traffic from people who want what you offer, and a map of the buyer journey from first question to final purchase. That is as true for a Toa Payoh dental clinic as it is for a SaaS company.
So the skill has not gone away. It has widened. You are no longer only researching what people type into Google; you are researching how they ask, what they mean, and which answers earn a mention when a machine does the summarising.
Keywords vs. search queries, and the types you’ll meet
Before you research anything, it helps to know what you are looking at. Keywords are not all the same, and the differences change how you target them. This section covers the vocabulary you will use for the rest of the process.
Keywords vs. search queries
A search query is the exact string a person enters. A keyword is the term you choose to optimise a page around. They often overlap, but not always.
Someone might search “best dentist near me toa payoh open sunday”. That is a query. The keyword you build a page around might be “dentist toa payoh”. One is messy and specific to a moment; the other is the target you can plan for. Keeping the two ideas separate stops you from trying to create a page for every literal phrase, which is impossible, and points you at the patterns underneath instead.
Branded vs. non-branded keywords
A branded keyword includes a company or product name: “Roots Digital SEO” or “Nike running shoes”. A non-branded keyword describes a need without naming anyone: “SEO agency singapore” or “running shoes for flat feet”.
Branded terms usually convert well because the searcher already knows you, but their volume is capped by how well-known you are. Non-branded terms are how new customers who have never heard of you find you. Most keyword research focuses on non-branded demand, because that is where growth comes from.
Head terms vs. long-tail keywords
Head terms are short, broad and high-volume: “keyword research”. Long-tail keywords are longer, more specific and lower-volume: “how to do keyword research for a shopify store in singapore”.
Head terms look attractive because of the traffic, but they are fiercely competitive and their intent is vague. Long-tail terms bring fewer searches each, but they convert better because the need is clear, and there are far more of them in total. A strong strategy targets a few head terms with pillar pages and captures the long tail with supporting content.
Matching terms, related terms and keyword clusters
Once you have a seed keyword, tools expand it in a few directions. Matching terms contain your seed phrase (“keyword research tools”, “keyword research for seo”). Related terms are semantically connected without containing the phrase (“search volume”, “seo content strategy”). A keyword cluster is a group of terms that all share one search intent and can be answered by a single page.
Clustering is the shift most people miss. You are not writing one page per keyword; you are writing one page per intent, and that page targets a whole cluster at once. We will come back to this, because it is where modern keyword research and AI search meet.
Keywords by search intent (informational, navigational, commercial, transactional)
Intent is the “why” behind a search, and it is the single most useful way to sort keywords. There are four common types.
Informational queries want knowledge: “what is keyword research”. Navigational queries want a specific site: “semrush login”. Commercial queries are researching before a purchase: “best keyword research tool”. Transactional queries are ready to act: “hire seo agency singapore”.
Matching intent is non-negotiable. If someone searches an informational term and lands on a hard sell, they leave. Transactional and commercial terms are the ones worth routing to your SEM (paid search) services and money pages; informational terms earn trust earlier in the journey.
The keyword metrics that actually matter
Every tool throws a wall of numbers at you. A few of them decide whether a keyword is worth targeting, and the rest are noise until you know the basics. Here is how to read the ones that count.
Search volume (and why Singapore volumes look small)
Search volume is the average number of times a keyword is searched per month, usually shown as a rolling 12-month average. It is the first number most people look at, and the most misread.
Here is the Singapore-specific trap. Global tools estimate volume from a sample, and in a market of under six million people, the true numbers are small and the estimates get shaky. A keyword showing “20 searches a month” in Singapore is not the same as 20 in the United States: the sample is thinner, so the figure is less reliable, and plenty of real demand gets reported as zero. We treat Singapore volumes as a rough signal of relative interest, never as an exact count. A term with “10 a month” can still be worth a page if the intent is commercial and the searcher is ready to buy.
Keyword difficulty
Keyword difficulty is a score, usually 0 to 100, that estimates how hard it will be to rank on the first page for a term. Most tools base it on the strength of the sites already ranking, measured through their backlink profiles.
Treat it as a guide, not gospel. Difficulty scores differ from tool to tool because each vendor calculates them differently, and none of them can see how relevant your specific site is to the topic. A high score on a term closely tied to your services may still be winnable; a low score in a niche you have no authority in may not. Read the score, then check the actual SERP.
Cost per click (CPC) and commercial value
Cost per click is the average amount advertisers pay for one click on that keyword in paid search. Even if you never run ads, it is a useful proxy for commercial value: advertisers only bid highly on terms that make them money.
A high CPC tells you a keyword sits close to a purchase. “seo audit singapore” will carry a higher CPC than “what is seo”, because the first is a buying signal and the second is curiosity. When you are choosing between terms of similar volume, CPC helps you spot the ones with revenue behind them.
Traffic potential vs. single-keyword volume
A page rarely ranks for just one keyword. It ranks for dozens, sometimes hundreds, of variations of the same idea. Traffic potential is the total search traffic the top-ranking page for a topic actually receives, across every term it ranks for, not the volume of your single target keyword.
This reframes how you value a topic. A keyword with a modest headline volume can sit on top of a huge pool of related searches. The way to estimate it is to look at the current top-ranking page and see how many keywords it already ranks for. If it pulls traffic from 300 terms, that is your real ceiling, not the one number your tool showed for the seed.
Business potential (will this keyword actually convert?)
The last metric is the one no tool reports: how likely a keyword is to lead to a sale for your business. You have to score it yourself.
A simple way is to rate each keyword from 0 to 3 on how well your product solves the searcher’s problem. A “3” means your service is the answer to that query. A “0” means the searcher will almost never become a customer, however much traffic the term brings. High-volume, low-business-potential keywords are the most common way to waste a year of content, so we weight this heavily when we choose targets.
How to do keyword research: a step-by-step process
Here is the process we use on client accounts. It works whether you have a full tool stack or nothing but a browser, and it deliberately starts with your website rather than with a tool, because the goal is rankings that earn business, not a spreadsheet of pretty numbers.
Step 1: Map the pages (and page types) worth ranking
Most guides start by brainstorming keywords. We start one step earlier, by asking which pages you need. Keyword research is not a hunt for terms in the abstract; it is a hunt for terms you can realistically build a page around and rank.
List the page types your business needs: service pages, location pages, product or category pages, and the blog topics that support them. A dental clinic needs pages for each treatment, each location, and supporting guides. Mapping this first means every keyword you find later has a home, and you never end up with a list of terms and nowhere to put them.
Step 2: Brainstorm seed keywords and topic buckets
Seed keywords are the starting phrases you expand from. You do not need a tool for this part; you need to think like your customer.
Write down the words you would use to describe what you sell, then group them into topic buckets. An SEO agency might have buckets for “seo services”, “keyword research”, “link building” and “local seo”. Talk to your sales team about the phrases prospects actually use, read the questions in your support inbox, and check the language competitors use on their pages. This raw list is the fuel for every tool step that follows.
Step 3: Expand with tools, Google Autocomplete and related searches
Now you widen the list. Free sources are surprisingly powerful here, and you should exhaust them before paying for anything.
Type a seed into Google and read the Autocomplete suggestions; those are real queries people enter. Scroll to the bottom of the results for the “related searches” block. Open the “People also ask” questions and note the ones relevant to you. Then run your seeds through a keyword tool to pull hundreds of matching and related terms at once. The free and paid options are covered in detail further down.
Step 4: Pull keyword-level data (volume, difficulty, intent)
With a long list in hand, attach data to each term so you can compare them. This keyword analysis step is where research turns into a decision: for every keyword you want volume, difficulty, and a read on intent.
A keyword tool gives you volume and difficulty in bulk. Intent you often have to infer from the phrasing and confirm on the SERP in the next step. The output of this step is a spreadsheet: one row per keyword, columns for volume, difficulty, CPC and a first guess at intent. Do not skip the spreadsheet; it is what turns a vague sense of “good keywords” into a decision you can defend.
Step 5: Check the SERP and confirm search intent
This is the step that separates people who rank from people who guess. Before you commit to a keyword, search it yourself and study the first page of results.
The pages that already rank tell you what Google thinks the intent is. If you target “keyword research” and the whole first page is in-depth guides, a thin 500-word post will not compete. If the results are all product pages and you planned a blog post, you have misread the intent. The SERP is the answer key; check it before you write, not after.
Step 6: Map keywords to pages (keyword mapping)
Keyword mapping is assigning each keyword, or each cluster of keywords, to a specific page on your site. It is the bridge between research and execution.
Take your researched list and match every term to a page from your Step 1 map, grouping terms that share one intent onto a single page. One page targets one primary keyword and the cluster of related terms around it. This stops two of your own pages competing for the same term, and it makes sure every page has a clear job. A simple spreadsheet with columns for URL, primary keyword and secondary keywords is all you need.
Step 7: Select the winners with a scoring checklist
You will always find more keywords than you can act on. The final step is choosing which to pursue first, using a repeatable checklist rather than gut feel. The next section breaks that checklist down criterion by criterion.
How to choose the right keywords (selection checklist)
When you are staring at a list of hundreds of candidates, these are the six checks we run on each one. A keyword that passes all six goes to the top of the queue.
Search volume
Volume tells you the size of the prize, read as a relative signal rather than an exact count, especially in Singapore. A term with steady demand is worth more than a term with almost none, but volume alone never wins the argument. Pair it with intent and business potential before you decide.
Search intent
Ask what the searcher wants and whether your page can give it to them. A term whose intent matches what you offer is worth more than a higher-volume term whose intent points somewhere else. If the intent is informational and you only have a sales page, either build the right kind of page or move on.
Relevance to your services
The keyword has to connect to something you actually sell or support. Ranking for a high-traffic term that has nothing to do with your business brings visitors who never convert and can drag your topical focus off course. Relevance keeps your content pointed at customers.
SERP intent (what’s already ranking)
Look at the type of pages ranking on page one. They reveal the format Google rewards for that term: guide, listicle, product page, or tool. If you cannot or do not want to produce that format, the keyword is not a fit however good its other numbers look.
Keyword difficulty
Weigh difficulty against your own site’s authority. A new site should target lower-difficulty, longer-tail terms and build up; an established site with strong backlinks can go after harder terms. Difficulty is only meaningful relative to your own strength, which is why the same score can be a green light for one site and a wall for another.
Factor in SERP features (image packs, video, snippets, AI Overviews)
The ten blue links are no longer the whole SERP. A results page might carry an image pack, a video carousel, a featured snippet, or an AI Overview, and each one changes how much traffic the classic listings actually get.
If a query is dominated by video, a blog post may struggle no matter how good it is, and a YouTube video might be the better play. If an AI Overview sits at the top, you want to be one of the pages it cites, which is partly a job for schema markup on your pages. Read the SERP features before committing, and pick keywords where you can win the format that is actually showing.
How to find the keywords your own website already ranks for
Before chasing new terms, harvest the ones you already have. Most sites rank for hundreds of keywords the owner has never looked at, and some sit just off page one where a small push pays off fast.
The free way is Google Search Console. Open the Performance report and sort your queries by impressions; you will see the terms Google already shows you for, with your average position for each. The gold is in positions 11 to 20, the top of page two. These are terms you nearly rank for, where improving an existing page is far easier than starting from scratch.
A rank tracker or an all-in-one SEO tool does the same job with more detail, showing ranking history and the keywords competitors rank for that you do not. But Search Console is free, accurate because the data is Google’s own, and the first place we look on any established site. Finding these quick wins is often the fastest return in a whole campaign, and it is worth knowing that SEO takes time to work so early wins matter for momentum.
Keyword research tools (free and paid)
Tools are where most guides start and where most budgets leak. You can spend nothing or a few hundred dollars a month, and the expensive option is not automatically the right one. Before we list them, a word of caution about what these tools can and cannot tell you.
Are keyword research tools flawed?
Yes, and it is worth being honest about it. Every keyword tool except Google’s own is working from estimated data, and even Google’s is built for advertisers, not for you.
Three flaws matter. First, data accuracy: third-party tools sample and model search volume rather than measure it, so two tools routinely disagree on the same keyword, sometimes by a wide margin. Second, low-volume blind spots: in a small market like Singapore, tools under-report or show zero for terms that carry real demand, because the sample is too thin to register them. Third, intent-blindness: a tool can tell you a keyword gets searches, but it cannot tell you whether those searchers want to buy, learn, or just browse. Only the SERP tells you that.
None of this makes tools useless. It makes them a starting point, not a verdict. The discipline is to use them for discovery and bulk data, then validate every serious candidate against the live SERP and your own judgement. Treat the numbers as directional, and you get the value without being misled by false precision.
Google Keyword Planner
Google Keyword Planner is the obvious first stop, and it is free. It sits inside Google Ads, and you need a Google Ads account to use it, but you do not have to run any campaigns or spend a cent to access it.
There is one important limit. On an account with no active ad spend, the Planner shows search volume as broad ranges, such as 1K to 10K, rather than exact numbers. Running an active campaign unlocks precise figures. For SEO that range is still useful as a rough guide, and the data has one unbeatable quality: it comes straight from Google, not from a third-party estimate. Its weakness is that its competition metric reflects paid, not organic, difficulty, so you cannot use it to judge how hard a term is to rank for organically.
Free keyword research tools
You can get a long way without paying anything. These free tools each do one part of the job well, and together they cover most of what a small business needs.
Google Trends
Google Trends shows relative interest in a term over time, not absolute volume. It is the fastest way to spot whether a topic is rising or fading, to compare two keywords against each other, and to catch seasonality. For Singapore you can filter to the country and see which terms spike and when, which is useful for planning content around local demand cycles.
AnswerThePublic
AnswerThePublic takes a seed keyword and visualises the questions people ask around it, pulled from autocomplete data. It is excellent for the “what do people actually want to know” part of research, and the questions it surfaces map neatly onto blog topics and FAQ sections. The free version limits your daily searches, but even a few queries produce a lot of ideas.
Keywords Everywhere
Keywords Everywhere is a browser extension that shows volume, CPC and competition data directly in your Google search results and across other sites. It is not fully free: it runs on a low-cost credit system for the exact figures. But it is cheap, it puts data where you are already working, and it will even surface metrics inside some AI chat tools, which ties into the AI workflow below.
Wordtracker / Ubersuggest (free tiers)
Both Wordtracker and Ubersuggest offer limited free tiers that return keyword ideas and rough volume figures. Ubersuggest gives you a handful of free searches a day and a clean interface for beginners. Wordtracker leans on search-partner data as an alternative source to Google. Neither free tier is generous enough for heavy use, but both are fine for occasional research or for cross-checking another tool’s numbers.
Paid all-in-one tools
When keyword research becomes a regular job rather than a one-off, an all-in-one platform saves hours. These tools combine keyword data, rank tracking, competitor analysis and site audits in one place. Prices below are indicative and change often, so check the current rate before you buy.
Semrush
Semrush is one of the two market leaders, with an enormous keyword database and strong competitor-research features. Its Keyword Magic Tool is a favourite for building large, well-organised keyword lists. Entry pricing sits at roughly US$139 a month at the time of writing, with a limited free account and a trial available. It suits businesses that want depth across SEO and paid search in one subscription.
Ahrefs
Ahrefs is the other market leader, known for the quality of its backlink data and its “traffic potential” and “parent topic” metrics, which push you to think in topics rather than single keywords. Its difficulty scores are widely used as a reference. Pricing is broadly comparable to Semrush. It is a strong choice if backlink analysis and content research matter as much as keyword volume.
Moz
Moz Pro offers keyword research, rank tracking and its well-known Domain Authority metric. Its keyword difficulty and “priority” scores are beginner-friendly, and the interface is approachable for people newer to SEO. It tends to sit slightly below the two leaders on database size, but it is a capable, more digestible option.
KWFinder (Mangools)
KWFinder, part of the Mangools suite, focuses on doing one thing well: finding long-tail keywords with clear difficulty scores, in a clean and simple interface. It is usually cheaper than the big platforms, which makes it popular with freelancers, small businesses and anyone who finds the market leaders overwhelming.
SE Ranking
SE Ranking is a full-featured platform that covers keyword research, rank tracking, site audits and competitor analysis, typically at a lower price point than Semrush or Ahrefs. It has become a common choice for agencies and small businesses that want most of the leaders’ capability without the leaders’ price. Its keyword data now also extends into AI-search visibility tracking, which is increasingly relevant.

Doing keyword research with no paid tools
You can run a complete keyword research process without paying for a single tool. Here is the free stack we would use if the budget were zero.
Start with Google Autocomplete, People Also Ask and related searches to build your seed list straight from the search results. Use Google Trends to compare terms and check seasonality. Run seeds through Google Keyword Planner for volume ranges from the source. Add AnswerThePublic for question ideas and Ubersuggest’s free searches for extra suggestions. Finally, pull the keywords you already rank for from Google Search Console, which is both free and the most accurate data you will find anywhere.
It takes more manual effort than a paid platform, and the volume figures are rougher. But the method is sound, and for a small Singapore business testing its first content, it is more than enough to start.
Using AI for keyword research
AI has changed this work in two directions at once. It is a tool you can research with, and it is a new place your customers search. Both matter, and both are covered here.
Using AI (ChatGPT & Claude) for keyword research
You can use ChatGPT, Claude and similar tools for keyword research, but you have to understand what they are good and bad at. They are excellent at the creative, structural parts of the job and unreliable at the numbers.
Use them to brainstorm seed keywords, group terms into topic clusters, generate question variations, and draft the intent behind a query. Ask an AI tool to “list the subtopics someone researching keyword research would want covered” and you get a strong content outline in seconds. What you must not do is trust an AI tool for search volume or difficulty. Language models do not have live access to search data, and they will produce confident numbers that are simply invented. Get your ideas and structure from AI, then get your data from a real keyword tool. Our AI SEO services lean on exactly this division of labour.
How AI search has changed keyword research (semantic intent, topic clusters, zero-click)
The bigger shift is in how people search. AI Overviews and chatbots answer questions directly, which changes what you are optimising for.
Three changes stand out. Semantic intent matters more than exact phrasing: search engines and AI systems now understand meaning, so you optimise for a topic and the intent behind it, not for one exact string repeated on a page. Topic clusters beat single keywords: covering a subject thoroughly across a well-linked set of pages signals genuine expertise, which is what these systems reward. And zero-click results are rising: when an AI Overview answers a query on the results page, fewer people click through, so the value of being the cited source goes up and the value of ranking tenth goes down.
The practical effect is that keyword research now feeds a topic strategy, not a list. You still find the terms, but you group them into clusters and build authority across a subject, because that is what earns visibility when a machine decides which sources to trust.
Optimising keywords for AI Overviews and chatbots (GEO/AEO)
A new label has appeared for this work: GEO (generative engine optimisation) or AEO (answer engine optimisation). It means shaping your content so AI answers cite it. The fundamentals overlap heavily with good SEO, with a few additions.
Lead your pages and sections with clear, self-contained answers, because AI systems lift concise, well-structured passages to build their responses. Cover topics thoroughly and cite primary sources, since authority and clarity are what these systems select for.
You can also add structured data such as FAQPage and Article markup to help machines parse your content. It is worth being precise about what that does today, though.
Google removed FAQ rich results from its search results through an update to its structured data documentation that began limiting the feature in 2023 and finished retiring it in 2026. FAQPage markup no longer wins you an expandable box in Google. The markup stays a valid schema type, and other search engines and AI systems can still parse it.
So mark up real question-and-answer content because it helps machines understand your page, not because it earns a SERP feature that no longer exists. The content doing the work, as always, is the visible answer on the page.
Keyword research for the Singapore market
Almost every keyword research guide you will read is written for the United States, and it quietly assumes American search volumes, American competition and American search behaviour. Singapore is a different market, and a few things change when you research here.
The first is volume distortion. Singapore’s population is small, so absolute search volumes are a fraction of what the same term shows in a large market. A keyword pulling tens of thousands of searches in the US might show a few hundred here, and global tools report our small numbers unreliably. You learn to read Singapore volume as a relative signal and to trust intent and commercial value more than the raw figure.
The second is local intent and modifiers. Singaporean searchers add “singapore”, “SG” or “near me” to commercial queries, and they search for neighbourhoods and MRT areas. “aircon servicing” and “aircon servicing bishan” are different jobs with different competition. Building local modifiers into your research surfaces terms that global tools and global competitors miss entirely.
The third is language and phrasing. Singapore is multilingual, and real queries mix English with local terms and the occasional Singlish phrasing. People search “cheap” and “best” and specific brand and place names in combinations a US-trained tool never anticipates. Reading actual Singapore SERPs, rather than trusting a tool’s suggestions, is the only way to catch these.
The last decision is local versus regional demand. Some Singapore businesses serve only the local market, and some can serve the region. That choice determines whether you research only .sg-intent terms or widen to Malaysia and the broader region, and it should be deliberate rather than accidental.
Keyword research by channel and use case
The core process stays the same across channels, but the emphasis shifts depending on where your content will live. Here is how the work changes for three common cases.
Keyword research for ecommerce
Ecommerce keyword research centres on commercial and transactional intent, and on the structure of your catalogue. You research category terms for collection pages, specific product terms for product pages, and comparison or “best” terms for buying guides. Because this is a deep topic in its own right, we have covered it separately in our ecommerce keyword research guide.
Keyword research for blog and content marketing
Content marketing leans towards informational intent and the top of the funnel. You research the questions your audience asks, the problems they are trying to solve, and the topics that build your authority in a subject. The aim is a cluster of related articles that cover a theme thoroughly, rather than a scatter of unrelated posts, because depth across a topic is what earns rankings and citations.
Keyword research for social media and YouTube
Social and video platforms have their own search behaviour, and their own search bars. On YouTube, you research the exact phrasing people use to find tutorials and reviews, using YouTube’s autocomplete as your primary source. On social platforms, hashtag and topic research matters more than classic volume. The principle carries over: find the language your audience uses, then match it.
Common keyword research mistakes to avoid
After years of client work, the same handful of mistakes come up again and again. Avoiding these will put you ahead of most of your competitors.
Chasing volume over intent
The most common mistake is picking keywords for their traffic and ignoring what the searcher actually wants. A high-volume term whose intent does not match your business brings visitors who bounce and never buy. Volume is worthless without matching intent behind it.
Ignoring keyword difficulty relative to your site’s authority
New sites often target the same head terms as established competitors and then wonder why they never rank. Difficulty only means something relative to your own authority. A young site should build on lower-difficulty, long-tail terms first and earn the right to compete for harder ones.
Trusting tool volumes as exact (especially in small markets)
Tool volumes are estimates, and in Singapore they are rough estimates. Treating “1,300 searches a month” as a precise, reliable figure leads to bad decisions. Read volumes as directional, cross-check important terms across sources, and never let a single number carry a decision on its own.
Targeting one keyword per page instead of a topic
Building a separate thin page for every keyword variation is an old habit that now backfires. Search engines and AI systems reward pages that cover a topic and its cluster of related terms thoroughly. One strong page targeting a cluster beats ten thin pages splitting the same intent, and it stops your own pages competing with each other.
Skipping the SERP check before committing
Choosing keywords from a spreadsheet without looking at the live results is guesswork. The SERP tells you the real intent, the format Google rewards, and the strength of who you are up against. Skipping it is how people write the wrong kind of page for a term and only find out months later.
How many keywords can (and should) you target?
There is a common misconception that one page targets one keyword. In reality a single well-optimised page can rank for hundreds of related keywords, because it covers a topic and all the variations people use to search for it.
So the honest answer to “how many keywords can I rank for” is: far more than you deliberately target, if you write for a topic rather than a phrase. Our best-performing client pages rank for hundreds of terms each, most of which we never explicitly listed.
As for how many you should actively track, that depends on the size of your site and your goals. A small business might track 20 to 50 priority keywords closely; a large ecommerce site might track thousands. Track the terms that map to your important pages and to revenue, review them regularly, and do not confuse a long tracking list with progress. What matters is ranking for the terms that bring customers, not the length of the spreadsheet.
Frequently Asked Questions
Keyword research in SEO is the process of finding and analysing the search terms people enter into search engines, so you can optimise your content to rank for those terms. It reveals what your audience searches for, how often, and how competitive each term is, which lets you create pages that match real demand and attract qualified traffic.
Yes. You can run a complete keyword research process using only free tools. Google Keyword Planner gives you volume ranges from Google's own data, Google Trends shows interest over time, Google Autocomplete and "People also ask" surface real queries, and Google Search Console shows the terms you already rank for. Free tiers of tools like Ubersuggest and AnswerThePublic add more ideas. The data is rougher than a paid platform's, but the method works.
You can, for part of the job. ChatGPT and similar AI tools are good at brainstorming seed keywords, grouping terms into topic clusters, and generating question variations. They are not reliable for search volume or difficulty, because they do not have live access to search data and will invent numbers. Use AI for ideas and structure, then confirm volume and competition with a real keyword tool.
Yes. Google Keyword Planner is free, though you need a Google Ads account to access it. You do not have to run ads or spend any money to use it. The one limitation is that accounts with no active ad spend see search volume as broad ranges, such as 1K to 10K, rather than exact numbers. Running an active campaign unlocks the precise figures.
Treat it as ongoing rather than one-off. A thorough foundational research project happens at the start of a campaign or a new site section. Beyond that, review your keywords every few months to catch new terms, shifting demand and seasonal trends, and revisit whenever you launch a product, enter a new market, or notice rankings slipping. Search behaviour changes, so your research should not stand still.
Start by mapping the pages your business needs, then brainstorm seed keywords for each. Expand those seeds using Google Autocomplete, related searches and a keyword tool, and pull volume, difficulty and intent for each term. Check the live SERP to confirm intent, map each keyword or cluster to a specific page, and prioritise using a checklist of volume, intent, relevance, difficulty and business potential. The result is a keyword-to-page plan you can execute.
There is no single best tool; the right one depends on your budget and needs. Google Keyword Planner and Google Search Console are the best free starting points. Semrush and Ahrefs lead on depth for serious, regular work. SE Ranking and KWFinder offer strong value at a lower price. For most small Singapore businesses, a combination of the free Google tools plus one affordable paid platform covers everything needed.
A single page can rank for hundreds of keywords, not just one. When you write comprehensively about a topic, the page naturally ranks for your primary keyword plus every related term, synonym and long-tail variation people use to search for the same thing. This is why targeting a topic and its keyword cluster, rather than one exact phrase, is the stronger strategy.
That depends on your site's size and goals. A small business might actively track 20 to 50 priority keywords, while a large ecommerce site could track thousands. Focus your tracking on the terms tied to your important pages and to revenue, rather than trying to monitor every possible variation. Regular review of a focused list beats a long list you never act on.
