Accessibility checker
Paste any address. We read the page the way a visitor gets it and name the accessibility problems in it, each against the WCAG criterion it belongs to.
What this cannot see
This reads the HTML of one page. Whatever it reports, these are not covered and they matter just as much:
- Most colour contrast. It is checked where an element sets both its own text and background colour directly, which is a minority of pages. Where the colours come from a stylesheet, judging them needs the computed styles a browser produces, so it is not guessed at. To check a specific pair, use the brand colour checker.
- Keyboard use. Whether every control can be reached and operated without a mouse, and whether you can see where you are.
- What a screen reader announces. Markup can be valid and still read as nonsense out loud.
- Anything behind a click. Menus, modals and anything a script builds after the page loads.
A clean result means the structural basics are right. It is not a statement that your site is accessible, and nobody should sell you one.

The website checker runs this same
analyser alongside SEO, content and page weight on any address. On a Webkio site, it runs
continuously as part of the Site Health score.
Questions
No, and that is the most important sentence on this page. This reads the HTML of one page and finds the problems that can be found that way: missing alt text, unlabelled form fields, links that say "click here", buttons with no name, headings in the wrong order. It cannot see colour contrast, whether the page can be used with a keyboard alone, whether focus is visible, or what a screen reader actually announces. A clean result means the structural basics are right, which is a good day, not a certificate.
Because "87% accessible" is a sentence that gets businesses into trouble. Accessibility is not a percentage, and a number drawn only from the checks a machine can run invites exactly the false comfort we would rather not sell. You get what was found, how serious each thing is, and which WCAG criterion it belongs to.
Possibly. It applies from 2025 to a wide range of businesses selling to consumers in the EU, with exemptions that commonly include the smallest microenterprises - and the UK has its own separate duties under the Equality Act. We are not the right people to tell you where you fall, and a tool that claimed to would be guessing about your business. What is true regardless: the problems below shut real customers out.
Because a page is what a machine can fetch and read honestly in a second. Most of these faults come from a template rather than a page, so fixing what this finds on your busiest page usually fixes it everywhere. Check a few of your different page types.
Yes - the same analyser runs inside the product, and the Site Health score on a Webkio site reports it alongside SEO and content. This page points it at any address, on any platform.
