Mobile Friendly
Google's been mobile-first indexing for years now, so this skill handles the technical SEO side of that reality. It covers viewport meta tags, responsive design patterns, content parity checks between mobile and desktop, and mobile usability requirements like touch target sizing and font minimums. The skill also addresses the AMP question directly, which is refreshing: it's still supported but no longer gives you a ranking boost, so for most sites you're better off focusing on responsive design and Core Web Vitals. Use this when you're debugging mobile usability issues in Search Console or setting up proper viewport configuration.

SEO Technical: Mobile-Friendly
Guides mobile-first indexing optimization and mobile usability. Google uses the mobile version of pages for indexing and ranking; mobile-friendliness is a ranking factor.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope (Technical SEO)
- Mobile-first indexing: Google primarily crawls and indexes mobile version
- Mobile adaptation: Responsive design, viewport, breakpoints
- Content parity: Mobile and desktop content should match (or mobile preferred)
- Mobile usability: Viewport, font size, touch targets, no intrusive interstitials
- AMP: Accelerated Mobile Pages—status and when to consider
Initial Assessment
