Mobile-First Indexing

Quick Definition

Mobile-first indexing means Google primarily uses the mobile version of your site for crawling, indexing, and ranking. As of 2025, every site is mobile-first indexed.

In context

If your mobile site has less content, hidden navigation, or different structured data than desktop, you're losing rankings even on desktop searches. Audit mobile rendering with Search Console's URL Inspection tool.
