Free Mobile Usability Quick-Check
Check your page for the structural patterns that most often break the mobile experience before Google's Search Console mobile usability report flags it for you. Free, one URL, no login.
Most mobile usability problems trace back to a handful of structural patterns
A missing viewport tag that lets the whole page render at desktop width. A nav bar with a dozen links and no hamburger menu. A body font set at 11px because it looked fine on a designer’s widescreen monitor. A pricing table dropped in with no responsive wrapper. None of it shows up in a desktop preview, but all of it adds up to the pinch-to-zoom, horizontal-scroll frustration that sends mobile visitors straight back to the search results. Most people comparing service providers, researching treatment options, or donating to a campaign do it from a phone at 11pm, not a desktop — a broken mobile layout costs a lead or a donor you already paid to attract.
This free check scans your page’s HTML for the same structural red flags we screen for before any client site goes live, so you know what to fix before Google's own mobile usability report (or an actual customer on their phone) finds it first.
- Several buttons measure under the 44px minimum tap-target size Google’s own mobile-friendliness guidelines recommend.

The Four Scoring Categories
- Viewport Meta Configuration
- Whether a viewport meta tag exists at all, whether it includes width=device-width, and whether it blocks pinch-zoom, the single most disruptive mobile setting on the page.
- Responsive Layout Signals
- Whether the page shows any visible sign of responsive breakpoints, and whether hardcoded fixed-width elements are likely to trigger horizontal scroll on a narrow screen.
- Font & Tap-Target Legibility
- Whether body text and other on-page text is set small enough to be illegible on a phone screen without zooming.
- Mobile Navigation & Interstitial Risk
- Whether a substantial nav menu collapses into a usable mobile pattern, and whether tables or other wide elements are wrapped for horizontal scroll safety.

- Tap Target
- A button or link sized and spaced so it can be reliably tapped with a finger without hitting the wrong element.
- Mobile-First Indexing

- Legible Font Size
- Body text large enough, generally 16px or more, to read comfortably on a phone without needing to zoom.
Mobile Usability Quick-Check FAQ
Is this a real Google Mobile-Friendly Test?
No, and we want to be very clear about that. This is a static-HTML scan of the page's markup and inline styles. It does not render the page on an actual device, does not execute JavaScript, and cannot measure true rendered tap-target sizes. Think of it as a fast first pass before you test the page directly on a phone, not a certified mobile-friendliness report.
What exactly does it check?
It checks four things: whether a proper viewport meta tag exists and allows zooming, whether the page shows any visible responsive layout signals, whether body and other text is set legibly for a phone screen, and whether a substantial nav menu and any tables are built to work on a narrow viewport.
Why does the viewport meta tag matter so much?
A missing or misconfigured viewport tag affects how every single element on the page renders on a phone, not just one section. Without it, mobile browsers render the page at a fixed desktop-style width and shrink it down, forcing visitors to pinch and zoom just to read anything. It's the single most disruptive mobile usability problem a page can have.
Why does mobile usability matter for a small business?
Most local search traffic now happens on a phone, and Google's Search Console flags real mobile usability issues that can affect rankings. More importantly, a visitor who has to pinch-zoom or hunt for a collapsed menu just leaves. Fixing the structural patterns this tool flags is usually cheaper and faster than most business owners expect.
Can this replace testing on an actual phone?
No. This is a static HTML scan, so it cannot see JavaScript-driven responsive behavior, external-stylesheet media queries, or true rendered tap-target sizes. Use it as a fast first pass to catch obvious structural issues, then test the page directly on a phone and in Google Search Console's mobile usability report for an authoritative check.
Can I check a page that requires a login?
No. The tool can only read pages that are publicly reachable, and it blocks local and internal addresses for security reasons.
Is this really free?
Yes. Enter a URL and your email, and you get your results immediately. No credit card and no sales call required to see your score.
What if my score comes back as high risk?
A high-risk score usually points to a specific, fixable pattern, most often a missing viewport tag or a nav menu with no mobile toggle. Your results include a plain-English list of what was flagged in each category, and you are welcome to book a free strategy call if you want help prioritizing fixes.
