Website Speed & Mobile-Friendliness Checker

Over 60% of search traffic in the US now comes from mobile devices, and Google has used mobile page experience as a direct ranking input since the mobile-first index rollout. If your site is slow or hard to use on a phone, that’s not a minor UX complaint — it’s a ranking problem and a lead-loss problem at the same time.

What This Website Speed Test Measures

Load time on both mobile and desktop connections
Core Web Vitals: Largest Contentful Paint (how fast the main content appears), Cumulative Layout Shift (whether things jump around as the page loads), and Interaction to Next Paint (how responsive the page feels once it’s loaded)
Mobile usability: tap target sizing, font legibility without zooming, viewport configuration
Render-blocking resources — scripts and stylesheets that delay the page from becoming usable

Every metric is shown against Google’s own pass/fail thresholds, so you’re seeing the same numbers Google is using to evaluate you, not an arbitrary internal score.

A Realistic Example

A service-based local business site with a 4-second mobile load time will typically see a measurably higher bounce rate on mobile than desktop for the identical page — visitors are less patient on a phone, full stop. Shaving that down to under 2.5 seconds usually comes from three things: compressing hero images, deferring non-critical JavaScript, and switching to a lighter-weight font-loading strategy. None of those require touching the site’s design.

How to Test If Your Site Is Mobile-Friendly

Enter your URL and the mobile-friendly test runs against a simulated mobile device — not just a smaller browser window, an actual mobile rendering engine. It checks whether buttons are large enough to tap accurately, whether text is readable without pinch-zooming, and whether the page reflows correctly instead of requiring horizontal scroll.

Why Slow Mobile Speed Costs You More Than Rankings

Even setting SEO aside, mobile speed is a direct conversion issue. A visitor who taps your Google Business Profile link expecting a phone number, hours, or a quick quote form isn’t going to wait through a slow load — they’ll hit the back button and call the next result instead. The technical fix and the business fix are the same fix here.

If your results show consistent mobile speed issues, that usually points to a deeper technical SEO gap — our technical SEO service addresses this directly, and for sites that need a rebuild rather than a patch, website designing starts from a performance-first template.
