Mobile-first indexing

Google’s approach to crawling websites prioritizing mobile versions for indexing and ranking.


Mobile-first indexing refers to Google's practice of using the mobile version of a website for indexing and ranking to help our primarily mobile users find what they're looking for. Google switched to this method because the majority of users access the internet via mobile devices. This means the mobile version of your website becomes the starting point for what Google includes in their index and the baseline for how they determine rankings.

Usage and Context

With the increase in mobile internet users, ensuring websites are optimized for mobile has become crucial. Mobile-first indexing means that when evaluating a website, Google will consider the mobile version as the primary version of the site. If a site doesn't have a mobile version, Google will still index the desktop version, but it may negatively impact the site's overall search rankings. Website developers and SEO specialists must prioritize mobile responsiveness and user experience to align with Google's mobile-first approach.


  1. What happens if I don't have a mobile version of my website?
    • Google will index your desktop version but your site may not perform as well in search results compared to sites with optimized mobile versions.
  2. How can I prepare my site for mobile-first indexing?
    • Ensure your site is responsive, load times are quick on mobile, and all content (text, images, videos) is accessible on mobile devices.
  3. Will mobile-first indexing affect my site's desktop rankings?
    • Yes, since Google uses the mobile version for indexing and ranking, it can impact both your mobile and desktop search rankings.
  4. Can I opt-out of mobile-first indexing?
    • No, Google has fully switched to mobile-first indexing, and it applies to all websites in the search results.
  5. How do I know if my site is indexed using mobile-first indexing?
    • Google will notify site owners through the Search Console when their site has been moved to mobile-first indexing.


Adapting to mobile-first indexing means enhanced visibility in Google search results, providing a better user experience for the growing number of mobile users, and staying competitive in an increasingly mobile-centric online world.


Mobile-first indexing reflects the changing landscape of internet usage, prioritizing mobile users' experience. As mobile internet use continues to grow, aligning with mobile-first indexing is not just beneficial but essential for SEO success. Sites optimized for mobile will not only rank better but provide a better user experience, meeting both the needs of users and the criteria of modern search engines.
