Why SEO Matters

Over 60% of all web traffic comes from mobile devices. Google exclusively uses the mobile version for indexing and ranking. If your mobile experience is poor — slow loading, tiny tap targets, unreadable text — you're losing both rankings and customers. Mobile is not optional.

Frequently Asked Questions

What is mobile-first indexing?

Mobile-first indexing means Google primarily uses the mobile version of your website's content for indexing and ranking. If your mobile site has less content or worse UX than desktop, your rankings will suffer — even for desktop searches.

My site is responsive — do I still need a mobile check?

Yes. Responsive design handles layout, but mobile SEO goes further: tap target sizing, font readability, interstitial handling, mobile page speed, and content parity. Many "responsive" sites still have significant mobile SEO issues.

How does mobile speed affect rankings?

Mobile page speed is a direct ranking factor (via Core Web Vitals). Google measures your site on simulated mobile connections. A page that loads in 1.5s on desktop might take 6s on mobile — that's a ranking penalty. Our checker identifies mobile-specific speed issues.
