Mobile Usability & Accessibility Tests
Google indexes the mobile version of your pages, so what visitors see on a phone is what gets evaluated. These checkers render or read the page as a mobile device would and flag tap targets that are too small, text that is too small to read, missing viewport tags and layouts that scroll sideways.
They are automated signals, not a full WCAG accessibility audit.
Favicon Checker
Checks the page declares a favicon, the icon browsers and Google search results show.
Webpage iFrame Test
Detects embedded iframes and checks each has a descriptive title.
Meta Viewport Tag Checker
Checks the page specifies a viewport tag matching the device width.
Webpage Tap Target Size Tester
Checks links and buttons are large enough to tap accurately on a touchscreen.
Font Size and Legibility Checker
Checks rendered text is not too small to read comfortably on mobile.
Mobile Responsiveness Tester
Checks the viewport tag, tap targets, font size and horizontal scroll together.
