How to read your accessibility results
Each problem names the element, with its selector and a snippet of its HTML, and the pages it appears on. Most accessibility problems come from a theme, a page builder block or a plugin, so one fix usually clears many pages.
Automated checks catch many common problems, but not all of them. Whether alt text actually describes the image, whether the reading order makes sense and whether the site works with a screen reader still need a person. The Professional audit adds keyboard checks: visible focus, controls that work with a keyboard, and pop-ups that keep focus.
This checker isn't a compliance certificate. It tells you what to fix; a full WCAG conformance review is a manual process.
Common accessibility problems, and how to fix them
These five account for much of what automated checks find on small-business sites.
01
Images without text descriptions
A screen reader announces an image with no alt text as "image" or reads out its file name. Describe what the image shows or does, and use empty alt text for pure decoration.
02
Form fields without labels
A placeholder isn't a label: it disappears as soon as someone types. Every field needs a visible label connected to it.
03
Buttons and links without names
Icon-only controls, like a menu or search icon, need an accessible name, or screen readers announce just "button".
04
Low color contrast
Light gray text on white is hard to read for many people, and for everyone on a phone in sunlight. Body text needs a contrast ratio of at least 4.5:1.
05
Zoom turned off on phones
A viewport setting that blocks pinch-to-zoom stops people with low vision from reading your site on a phone. It's one line in the page head.

Accessibility checker FAQ
Is the accessibility checker free?
Yes, with no signup. The free audit runs 13 automated accessibility checks on up to 25 pages, along with SEO, speed, security and contact checks.
Does it test against WCAG?
The checks are based on WCAG 2 success criteria and run with axe-core, a widely used open-source accessibility engine. Automated testing covers part of WCAG; the rest needs manual review.
Will fixing these issues make my website ADA compliant?
No tool can certify that on its own. Fixing what this checker finds removes common barriers and is a sensible first step. For legal questions, talk to a qualified professional.
What does the Professional audit add for accessibility?
Keyboard checks (visible focus, controls that work with a keyboard, pop-ups that keep focus, a skip link), heading order, table headers, video captions and error messages linked to their fields, on up to 150 pages.
Why does one problem appear on so many pages?
It's usually in your header, footer or theme, which appear on every page. Fix it there once and it clears everywhere.
Can it check pages behind a login?
No. The checker reads public pages only and never logs in or submits forms.
