Use both. A WordPress accessibility checker is a fast, repeatable first pass for issues its rules can detect; manual testing is essential for keyboard operation, meaning, context, and whether people can complete real tasks. A clean scan is not proof that a site is accessible.
What each approach can tell you
Automated accessibility checkers
A checker can quickly scan pages and flag detectable technical issues. For example, the Equalize Digital Accessibility Checker lists checks for empty links, missing form labels, insufficient color contrast, heading-order issues, and improper link use. These findings are useful because they make common problems easier to spot and revisit after updates. Equalize Digital Accessibility Checker
Results are limited to the tool’s rules and the content or states it scanned. The Equalize Digital listing says its free version scans posts and pages but excludes custom post types; bulk full-site scanning and custom post types require Pro. Those are limits of that product and plan, not universal limits of WordPress checkers. Equalize Digital Accessibility Checker
Manual testing
Manual review adds human judgment where a rule-based scan cannot determine whether content makes sense or whether an interaction works for a person. W3C WAI notes that some accessibility checks cannot be automated and require manual intervention. W3C: Selecting Web Accessibility Evaluation Tools

Keyboard-only testing can reveal whether users can reach and operate controls, see where focus is, and complete important flows. Learn WordPress’s accessibility testing activity demonstrates keyboard navigation and the difference between structural findings and questions of context and usability.

Why a checker cannot replace manual testing
A scan can report only what its checks are designed to recognize on the pages and states it examined. It cannot reliably decide whether alternative text describes an image appropriately, whether link text makes sense out of context, or whether a person can complete a task using the site’s menus, forms, dialogs, and other interactions.

Even the Equalize Digital plugin says that no automated tool or plugin can ensure a website is fully accessible. Treat a passing scan as useful evidence about the checks performed—not as a certification of the whole site. Equalize Digital Accessibility Checker
How to choose the right balance
| Question | Checker | Manual testing |
|---|---|---|
| What does it do best? | Consistently flags detectable technical issues covered by its rules. | Evaluates interaction, context, and whether real tasks are usable. |
| What limits the result? | Supported checks, scan scope, and the pages or states examined. | Requires time and a person who can evaluate the experience; some testing may call for assistive technology or specialist expertise. |
| When is it especially useful? | As a repeatable first pass and after content or interface changes. | For reviewing key user flows and findings that depend on meaning or operation. |
The two methods answer different questions, so choosing one instead of the other leaves a gap. Start with an automated scan to find clear issues efficiently, then spend manual effort on representative pages, templates, and interactions—especially those important to your users.

A practical checker-plus-human workflow
- Choose a checker with documented coverage. Review which standards and issue types it supports, and understand its scan scope before interpreting a clean result.
- Scan representative pages and templates. Include the kinds of content and layouts your site actually uses. Check whether important custom post types or interactive states fall outside the tool’s coverage.
- Fix clear findings and rescan. Address issues such as missing form labels or empty links, then rerun the scan to see whether those findings are resolved.
- Navigate with a keyboard. Move through menus, forms, dialogs, and other important interactions without a mouse. Check that focus is visible, controls can be operated, and the intended task can be completed.
- Review content in context. Check whether alternative text and link text communicate the right information. The existence of an alt attribute or link label alone does not establish that its wording is useful.
- Bring in more expertise when warranted. Assistive-technology testing and qualified accessibility expertise may be appropriate when site complexity, organizational needs, or the confidence required exceeds what a basic check and keyboard review can provide. There is no single audit scope that fits every site.
Make this a recurring practice rather than a one-time launch check. The Equalize Digital listing says its plugin rescans when a post or page is saved and also offers a manual scan action; regardless of tool behavior, site owners need to decide which pages, templates, and interactions to revisit after changes.

The Equalize Digital listing describes its findings as relating primarily to WCAG Level A and AA criteria and maps checks to criteria. That is a description of this plugin, not of every checker. WCAG-related scan results also should not be treated as a universal legal-compliance conclusion: legal requirements can depend on jurisdiction, organization, and the service or content involved.
