Mobile-First Indexing & Responsiveness
Google now crawls and ranks nearly every site using its mobile crawler, not the desktop version — which means a page that looks fine on a laptop but breaks on a phone is invisible to the ranking algorithm that matters. This section covers how mobile-first indexing actually works, how to audit your responsive design, and the tap targets, viewport rules, and parity checks that keep mobile users converting instead of bouncing.
