What Is Mobile-First Indexing?

Mobile-first indexing means Google predominantly uses the mobile version of a website's content for crawling, indexing, and ranking. Since most searches happen on mobile, the mobile experience is now the primary one Google evaluates.

How to prepare for mobile-first indexing

Make sure your mobile site contains the same content, headings, structured data, and metadata as desktop - responsive design handles this automatically. Avoid hiding important content on mobile, ensure images and links work, and confirm the mobile page is fast and easy to tap. Check status in Search Console.

Pro tip
If important content sits behind mobile tabs or accordions, make sure it is still in the HTML - Google ranks what is present in the mobile version.
Key takeaways
Google ranks based on your site's mobile version.
Mobile and desktop should contain the same content and metadata.
Hiding content on mobile can cost you rankings.
