What is WCAG?

WCAG, the Web Content Accessibility Guidelines, is the W3C standard for making websites usable by people with disabilities; version 2.2 is the current one.

Also called: Web Content Accessibility Guidelines

Why it matters for a small business site

An accessible site works for more people, including those with low vision, colour blindness or a tremor, and those who use a keyboard or a screen reader, and it tends to be easier for everyone else too. Many accessibility laws and purchasing rules refer to WCAG, most often at level AA, so check what applies where you operate.

How to check yours

  1. Start with an automated checker (WAVE, axe or the Lighthouse panel in Chrome). It catches some problems, like missing alt text and low contrast, but not all of them.
  2. Use the site with only a keyboard: press Tab through it and check you can always see where you are and reach everything.
  3. Zoom the browser to 200% and check nothing is cut off or overlapping.

What good looks like

Pages that meet WCAG 2.2 level AA: readable contrast, described images, labelled form fields, headings in a logical order, everything usable by keyboard with a visible focus outline, and tap targets that aren’t tiny (at least 24 by 24 pixels at AA).

Common mistakes

  • Adding an “accessibility overlay” widget and assuming it fixes the site. It doesn’t change the site’s own code.
  • Removing focus outlines because they look untidy.
  • Form fields with placeholder text but no label.
  • Treating one automated scan as proof the site is accessible.
Free site audit

See how your current site does

The free audit checks a few WCAG basics on your first screen (text and button contrast against AA, heading order, meaning shown by colour alone). It isn’t a full accessibility audit.

One page · the first screen · design, contrast, wording

Printed big on the certificate, with the site's address under it. Plain text — links are removed.

Free · no sign-up · one page, above the fold

This is the simple audit. Advanced audits check up to 20 pages, pages behind a login, and flows walked by AI — with an account on Pro.
