WordPress accessibility hardening checklist

WordPress powers a large share of public-facing sites for small agencies, healthcare practices, and nonprofits — exactly the buyers who increasingly face accessibility scrutiny. Most accessibility gaps on a WordPress site aren't theme bugs; they come from content authoring, form plugins, and a handful of predictable patterns in the block editor. This checklist walks through the categories in the order a developer or content editor would actually touch them, with the specific WCAG criterion each item maps to so reviewers can trace a fix back to the standard.

• ✓Theme and site-level checks: skip links, landmarks, focus visibility, color contrast
• ✓Content authoring in the block editor: heading order, alt text, link text, tables
• ✓Forms and navigation: labels, error messages, focus order, mobile menu patterns
• ✓Plugin review: the five categories most likely to introduce accessibility regressions
