About this plugin
2 Level A and AA from the admin dashboard. It runs the widely used axe-core engine in your browser against the fully rendered front end of each page, so it sees what visitors see: computed colour contrast, ARIA, headings, landmarks, form labels, images, links and more.
js or headless browser on the server. If your site runs WordPress, it can be scanned.
What you get
- Full-site or single-page scans. Posts, pages, public custom post types (including WooCommerce products) and, optionally, category and tag archives. Start a single-page scan from the “Scan accessibility” link in the toolbar while viewing any published page.
- Real rendered-page analysis with axe-core 4.10 plus extra checks for generic link text (“click here”), placeholder-only form fields, links that open new windows without warning, and linked PDF documents.
- Best-practice checks (optional, on by default) for headings, landmarks and page structure. They are reported as warnings because they are not strict WCAG failures.
- Clear, actionable issues. Every finding has a severity (Critical, Major, Minor, Warning), the WCAG success criterion, the affected page, the element and its HTML, a recommended fix and a link to documentation.
- An accessibility score from 0 to 100 for every scan, with Excellent, Good, Needs Improvement and Poor bands, and a progress-over-time chart.
- Dashboard with issues by severity, WCAG category distribution, the most common problems and recent scans.
- Optional automatic fixes you can switch on one by one: skip link, visible keyboard focus, underlined content links, a language attribute, new-window warnings, zoom-friendly viewport, removal of positive tabindex and redundant title attributes, and search-form labels.
- CSV and JSON export of every scan for your team, agency or audit records.
- Works on single sites and multisite networks, including network activation.
What automated testing can and cannot do
Automated tools, including this one, find a meaningful share of accessibility problems, but not all of them. Many WCAG requirements (meaningful alternative text, logical reading order, captions, keyboard-only workflows, plain language) still need a human review. Esmo Accessibility Scanner helps you find and fix issues faster; it does not certify that a site is accessible or legally compliant with the ADA, the European Accessibility Act, EN 301 549 or Section 508.
Privacy
- Scans run on your own site and in your own browser. Page content and results are never sent to the plugin author or any third party.
- Results are stored in your WordPress database and removed when you delete the plugin.
- The issues list links to rule documentation on dequeuniversity.com and w3.org. Those sites are only contacted if you click a link.
- While scanning, pages are loaded in a hidden frame as the logged-in administrator, so scripts on your pages run just as they do when you open them yourself. Analytics or ads on your site may count those page views.
- Automatic fixes only change your site’s front end, and only the ones you enable.
