Mobile SEO Checker

Over 60% of small business searches happen on phones. If your site isn't mobile-friendly, you're losing customers — and rankings.

Free • No signup required • Results in 60 seconds

Since 2019, Google uses mobile-first indexing — it judges your website on its mobile version, not desktop. If your site is hard to use on a phone, you'll be outranked by competitors with mobile-friendly sites every single time.

This free check verifies your mobile responsiveness, tap targets, font sizes, popup behavior, and Core Web Vitals — the three specific performance metrics Google uses for ranking.

Responsive layout test
Tap target spacing (44×44px minimum)
Font size readability check
Intrusive popup detection
Core Web Vitals (LCP, INP, CLS)
Image and form mobile-friendliness

Frequently asked questions

Google uses the mobile version of your site as the primary basis for indexing and ranking — even when someone searches from a desktop. If your mobile experience is broken, your desktop rankings suffer too.
