Mobile search queries have consistently outpaced desktop searches since 2017, accounting for around 57% of all website traffic by August 2023. By this, Google’s adoption of mobile-first indexing comes as no surprise.
With mobile-first indexing, Google signals site owners to pay attention to mobile friendliness. This ensures that users have the best experience while browsing the sites via their mobile devices.
As an SEO agency that adapts to the ever-changing Google updates, we realise that this change has a huge impact on the digital landscape. Those who want to maximise their SEO efforts must transform the way they design their websites and create their content.
Now that you’re here, we’ll break down how mobile-first indexing works and explain what it means for your SEO efforts. Let’s continue the discussion!
What Is Mobile-First Indexing?
Mobile-first indexing is a way that Google prioritises the mobile version of a site’s content for indexing, determining how it ranks in the search results. This algorithm update is carried out as a response to a peak in search queries coming from mobile devices.
Previously, Google relied heavily on desktop-first indexing, in which they evaluated desktop versions of content for indexing and ranking. Given that mobile phones were not as advanced as they are today, this algorithm is becoming obsolete and is gradually phased out as Google transitions to mobile-first indexing.
Unfortunately, many websites nowadays only cater to desktop searches. It may be because the owners don’t care or don’t know how to adapt their site design for mobile-first indexing– either way, these types of sites may lose relevance for mobile users.
If you fall into this category, don’t be surprised if you have trouble ranking effectively despite your SEO efforts. With the current mobile-first indexing algorithm, keep in mind that the mobile version of your site should take precedence over everything else.
Mobile-First Indexing VS Mobile Usability: What’s The Difference?
Mobile-first indexing and mobile usability are two different but related concepts. They function similarly in website optimisation for mobile devices, yet address different aspects of mobile user experience, as explained below:
- Mobile-first Indexing:
Mobile-first indexing is a way that Google prioritises the mobile versions of a site’s content for indexing and ranking. This algorithm entails smartphone Googlebot crawling the content’s mobile versions to determine its relevance and rank it in the search results.
With the implementation of mobile-first indexing, site owners are obligated to optimise their content’s mobile versions. If they neglect to do so, they’re at risk of experiencing a negative impact on their search engine rankings.
- Mobile Usability:
Mobile usability refers to how user-friendly and functional a site is when accessed on mobile devices. Its main focus is to deliver a smooth and efficient experience for users while they navigate a site using mobile devices.
We can assume that mobile usability is a part of mobile-first indexing. With Google’s shift towards providing users with the most relevant and useful information, implementing mobile usability becomes an essential aspect of adapting to mobile-first indexing.
When Did Google Implement Mobile-First Indexing?
Google didn’t implement mobile-first indexing immediately. Instead, they took a gradual approach over the course of several years.The gradual shift assisted Google in solidifying their smartphone Googlebot while also allowing businesses to progressively adapt to the innovation and improve user experience.
The following is an overview of Google’s journey to implement mobile-first indexing over the past few years:
- 2016 – The Initial Plan
Google first announced their initial plan to move towards mobile-first indexing back in November 2016. This plan was announced as a response to the fact that more and more people are browsing Google using their mobile devices.
Google predicted that continuing to rely on desktop-first indexing would be obsolete in the near future. People browsing Google on their smartphones will have a less pleasant experience if they rely on the desktop version of content for indexing and ranking.
Not only did Google announce that they would transition to mobile-first indexing, but they also planned to change their algorithms to prioritise the mobile version of a site’s content for ranking. They intended to do this over the next few years following the announcement.
- 2019 – Mobile-First Indexing As a Default For New Sites
Years went by and Google continued to refine their smartphone Googlebot to support their initial plan of prioritising mobile-first index over the desktop-first index. In May 2019, Google finally took a big leap and announced that they were going to set mobile-first indexing as a default for new sites.
The plan of setting mobile-first indexing as a default for new sites was about to be implemented starting in July 2019. However, Google remained crawling and indexing desktop versions of content from older sites, as they improved their smartphone Googlebot.
- 2020 – Mobile-First Indexing For All Domains (Postponed)
After making the algorithm mobile-first indexing as a default for new sites back in 2019, Google has finally decided to implement the algorithm for all sites in 2020. This decision was announced in March 2020 and will begin in September 2020.
Unfortunately, the COVID-19 pandemic hit unexpectedly. Many businesses are struggling, and many have had to shut down due to the circumstances, leading Google to think that fully implementing mobile-first indexing will be counter-productive.
Due to unfavourable conditions during the COVID-19 pandemic, finally in July 2020 Google announced that they were postponing fully implementing mobile-first indexing until March 2021. Still, when they announced this, 70% of sites were already mobile-first indexed.
- 2021 – Full Switch To Mobile-First Indexing
In March 2021, Google finally decided that mobile-first indexing is a default algorithm for all sites. All domains will be assessed by Google for ranking in the search results based on their content’s mobile version.
This, in turn, requires all site owners to adapt to the mobile-first indexing algorithm to thrive their SEO. They need to ensure that the mobile version of their content is efficient so that Google can find out its relevance and help them achieve optimal ranking in search results.
Why Is Mobile-First Indexing Important?
Amidst the ever-increasing use of mobile devices to browse the internet, mobile-first indexing becomes an important part that Google implements to ensure that users get the most relevant and accessible content.
That being said, the primary significance of this algorithm is to cater to the needs and preferences of mobile users, ensuring that their browsing experiences are seamless, engaging, and aligned with their search intent.
By centering content around mobile devices, sites can effectively deliver what users are seeking, right at their fingertips. Whether it’s informative articles, engaging infographics, or transactional services, this algorithm ensures that users can effortlessly find what they’re looking for.
Benefits of Mobile-First Indexing
As previously highlighted, mobile-first indexing guarantees users access to the most pertinent and easily accessible content, all with an enhanced overall browsing experience. Yet, how do these perks manifest in tangible outcomes?
Cross Device Experience
Websites that have been optimised for mobile-first indexing are typically accessible across multiple devices. The interface resolution will adjust seamlessly based on the device the user is using.
Faster Page Load Speed
With the implementation of mobile-first indexing, Google signals site owners to improve their page load speed as part of the best user experience parameter that influences rankings in the search results.
Better Local SEO
Mobile-first indexing has an inherent synergy with local SEO strategies, which is especially important for businesses looking to capture local markets. Sites that take a mobile-first approach seamlessly connect local users with relevant information, services, or establishments, encouraging physical engagement with businesses.
11 Common Mistakes To Avoid With Mobile-First Indexing Transition
The mobile-first indexing implemented by Google has made many businesses start trying to adapt to this algorithm. Unfortunately, despite their best intentions, many do not understand the correct strategy and fall into making mistakes.
Don’t let you make the same mistake so that your SEO efforts are not in vain. In the following, we describe the common mistakes that often occur in businesses trying to adapt to the innovation made by Google:
- Neglecting Mobile Usability
The allure of technical complexities of technical intricacies in adapting to the recent algorithm can overshadow the importance of user experience. Unfortunately, neglecting mobile usability can result in frustrated users and lowered search results.
Therefore, mobile-first indexing and mobile usability must go hand-in-hand, ensuring that users can engage with your site’s content seamlessly. Afterall, they’re the most important part that helps your site thrive.
- Ignoring Content Equivalency
Equivalency between mobile and desktop versions of content is important to ensure users can still get relevant information when browsing for it in Google. In many cases, sites display less content on mobile devices than what is seen on desktop devices.
Given that mobile displays are narrower than desktop displays, showing less content on mobile devices is completely understandable. In this case, however, Google will be unable to index all of the content that determines its relevance for ranking in search results.
- Overlooking Page Load Speed
Page load speed is paramount for providing users with the best experience. Overlooking this particular part will only cause frustration in users, increasing the chances of them abandoning your site and impacting your search performance negatively.
- Poor Mobile Redirects
Mobile redirects help you to automatically mobile users to a mobile-optimised website or subdomain. Unfortunately, mishandling Mishandling mobile redirects can result in erroneous navigation and confused users.
- Blocking Resources

Duplicate content management issues can perplex search engines, making it difficult for them to determine preferred versions. Using canonical tags and hreflang annotations diligently assists search engines in directing them to the correct content, preserving search ranking integrity.
- Ignoring Mobile Analytics
Failing to pay attention to mobile-specific analytics deprives businesses of important insights for optimising user engagement and conversions on mobile devices. At the same time, data-driven decisions are essential for long-term success in mobile-first indexing.
- Inadequate Testing
Thorough testing of the mobile experience across a wide range of devices and scenarios is critical for identifying and correcting design flaws and functionality gaps. Comprehensive testing ensures that the user interface is smooth and responsive, increasing overall user satisfaction.

Underestimating the importance of mobile content customization can lead to poor user experiences and decreased search visibility. Prioritising mobile content ensures that your site is effective across all devices.
