Mobile-first indexing
Google announces the gradual switch to indexing that relies first on the mobile version of pages for crawling, indexing and ranking.
Key points
- Google announces the gradual shift to indexing based first on the mobile version.
- Crawling, indexing and ranking rely on the mobile rendering of pages.
- Any content absent from the mobile version risks no longer being taken into account.
- The mobile version becomes the SEO reference.
Analysis
Mobile-first indexing reverses the historical logic: it is the mobile version of a page, and not the desktop version, that serves as the reference for crawling, indexing and ranking. Content, links and structured data absent from mobile risk being ignored.
This shift, then rolled out gradually over several years, establishes the mobile web as the norm. It requires content parity between mobile and desktop and renders obsolete any strategy that lightened the mobile version at the expense of information.
What to do
- Ensure content parity between the mobile and desktop versions (text, images, structured data).
- Check that meta tags, canonicals and internal linking are identical on mobile.
- Verify the rendering and indexing of the mobile version through URL inspection tools.
The mobile version becomes the reference for SEO. Any content missing from mobile risks no longer being taken into account.
