Mobile-First Indexing

Search engines predominantly use the mobile version of content for indexing and ranking.

Definition

Mobile-first indexing means that search engines primarily use the mobile version of a site’s content for indexing and ranking. Discrepancies between mobile and desktop (hidden content, blocked resources, differing metadata) can cause ranking and coverage issues. Ensuring parity, responsive design, and strong performance on mobile is essential for SEO resilience.
