Technical SEO & website checks

Website accessibility checker.

Check any page for the accessibility problems that automated tests can catch: missing alt text, unlabelled form fields, links and buttons with no name, skipped heading levels, disabled zoom, missing page language and more. Each issue links to the WCAG rule behind it.

How to use the website Accessibility Checker

  1. Enter a page address. Check your home page, contact page and any page with a form.
  2. We load the page and run the automated checks against its HTML.
  3. Fix the red items first: they block people from using the page at all.
  4. Then test by hand: try the page using only your keyboard, and zoomed to 200%.

Why accessibility matters for a business website

Around one in six people lives with some form of disability, and many more use the web with a temporary injury, an old phone, bright sunlight or a slow connection. An accessible site works for all of them. It's also increasingly a legal expectation: the ADA in the US, the Equality Act in the UK and the European Accessibility Act all apply to many business websites.

There's a search benefit too. Alt text, clear headings, descriptive links and proper labels are exactly the signals search engines and AI tools use to understand a page.

What automated checks can and can't find

Automated tools catch roughly a third of accessibility problems: the ones visible in the code, like a missing label or alt attribute. They can't judge whether alt text is actually useful, whether colour contrast works over an image, whether a menu can be used by keyboard, or whether the page makes sense read aloud. A clean result here is a good start, not a certificate of compliance.

The most common problems on small business sites

  • Social media and logo links with only an icon and no text, which screen readers announce as just "link".
  • Contact forms that use placeholder text instead of labels.
  • Menu and search buttons with no accessible name.
  • Images with no alt text, or alt text that's just the file name.
  • Zoom disabled in the viewport tag, which stops people enlarging text on phones.
  • Headings chosen for their size rather than their level, so the outline jumps around.

Quick manual tests to do next

Three tests take ten minutes and catch most of what automation misses. If they turn up problems, our website redesign and UI/UX design work builds accessibility in, rather than patching it afterwards.

  • Unplug your mouse and use Tab, Shift+Tab and Enter. Can you reach and use every link, button and form field? Can you always see where you are?
  • Zoom the browser to 200%. Does anything overlap or disappear?
  • Turn on your phone's screen reader (VoiceOver or TalkBack) and listen to your home page for one minute.
Questions

About the website Accessibility Checker.

Does passing this checker make my site WCAG compliant?

No. Automated checks find roughly a third of issues. Full compliance needs manual testing with a keyboard and a screen reader as well.

Which WCAG version does it check?

Its rules come from WCAG 2.2, levels A and AA, limited to what can be tested automatically from the page HTML.

Does it check colour contrast?

Not yet. Contrast depends on the final rendered colours, including CSS and background images, which needs a browser. Use a dedicated contrast checker for your text and background colours.

Can accessibility problems hurt SEO?

Indirectly, yes. Missing alt text, poor headings and vague link text make a page harder for search engines to understand, just as they do for people using screen readers.

Do accessibility overlay widgets fix these problems?

Usually not. Overlays can't reliably fix the underlying code, and many disabled users find them get in the way. Fixing the site itself is the dependable route.
