原文外掛簡介
ADA Compliance & Accessibility Checker – WCAG 2.2, Section 508 scans your posts and pages for real, code-level accessibility defects — missing alt text, broken heading structure, unlabeled form fields, low-contrast text and more — and shows you exactly what to fix and why, right inside the post editor. Several of the most common issues can be fixed with one click, and 12 optional site-wide fixes correct common problems across your whole site, including your theme — all free, with no account or license required.
Unlike accessibility overlay widgets, this plugin does not claim to make your site instantly “compliant.” It finds real WCAG 2.x and Section 508 failures in your actual markup so you, or your developer, can fix them.

Scanning
Unlimited posts and pages, on unlimited sites — no artificial cap of any kind on the free tier

On-demand “Start Scan” of your whole site, processed in safe background batches so it never times out
57 individual accessibility checks (37 warnings, 20 best-practice alerts), covering:
Images: missing, empty and invalid alt text; redundant alt/title; aria-hidden conflicts; image maps; self-linked images; invalid longdesc references
Links: empty links, ambiguous link text, adjacent duplicate links, redundant link text, unannounced new-window links, bare URLs as link text, unlinked email addresses, broken same-page anchors, links dressed up as buttons
Headings: missing, empty, skipped levels, missing or duplicate H1
Forms: missing, empty or duplicate labels, mismatched label targets, ungrouped related fields
Buttons: empty buttons with no accessible name
Tables: missing or empty headers, invalid scope, layout tables, orphaned header references
ARIA: invalid element references, empty labels, missing page language
Media: autoplaying audio/video with no controls, embeds with no fallback text, audio/video with no nearby transcript mention
Content hygiene: duplicate or blank titles, redundant title attributes, unreadable viewport-unit font sizing, fake paragraph spacing, malformed lists, duplicated table captions, deprecated blink/marquee elements
Color & zoom: inline text/background combinations below the 4.5:1 minimum, absolute font sizing, viewport tags that block pinch-zoom
Keyboard access: click-only handlers, disrupted tab order, meta-refresh redirects, JavaScript-only navigation menus
WCAG 2.2: minimum target size (2.5.8), focus not obscured (2.4.11)
Fix issues without leaving wp-admin
Seven of the checks above include a real, working one-click Fix — free, unlimited, with no license required:
Empty headings removed
Missing form labels added (using the field’s own placeholder or name, never invented text)
Redundant title attributes removed
Positive tabindex clamped back to zero
Site language set automatically from your site’s own locale
A visually-hidden “(opens in a new window)” notice added to unannounced new-window links
rel=”noopener” added to new-window links, closing a real security gap too
Every fix is verified immediately after applying it — the plugin rechecks that exact spot against the same rule that flagged it, and reopens the issue for manual review rather than marking it fixed if it’s still failing.
Site-wide accessibility fixes
The Accessibility Fixes screen has 12 free fixes that correct common problems on every page as it loads, including markup from your theme and other plugins. Each one is off until you turn it on:
Add page language & text direction — every page declares its language and text direction, so screen readers pronounce it correctly
Add a “Skip to main content” link — keyboard users can jump past the menu (not added if your theme already has a working one)
Allow pinch-to-zoom on mobile — removes viewport settings that stop visitors zooming in
Always-visible keyboard focus — a clear outline around whatever a keyboard user is on, in a color you choose
Restore natural keyboard order — removes forced tab positions so Tab follows reading order
Underline links in content — links in your text stand out without relying on color; menus and buttons keep their style
Announce links that open a new tab — screen readers hear “opens in a new window”
Keep every link in the same tab — stops links opening new windows on their own
Label search boxes — search fields and icon-only search buttons get a name
Label comment form fields — Name, Email, Website and Comment are always announced
Block empty searches — a clear, announced “Please enter a search term” instead of a page listing every post
Remove redundant tooltip text — tooltips that only repeat alt text, link text or a label are removed; tooltips that add information are kept
These fixes never change your saved content and never run inside page builder editors, so you can switch any of them off again at any time. The Dashboard keeps listing the original issues — use its one-click Fix to correct your content permanently.
Where you see it
A dashboard with an issue summary, a compliance score that rises as you fix issues, and a per-check breakdown
A filterable, sortable issues list — filter by status, error type or post type, search by title or post ID, and Fix, Ignore, Recheck or View the offending markup for any issue
A Block Editor sidebar panel showing the open issues for the post you’re editing, with a one-click Recheck that rescans without a full save
A matching notice for the Classic Editor
An Accessibility Fixes screen where you switch each site-wide fix on or off
A Guidelines Reference page explaining every check in plain English, with its WCAG citation
A Site Health status card summarizing your site’s open issues
A Help page with documentation, an accessibility consult link, and — once you’re ready — the upgrade path to Pro
Configuration
Choose which post types are scanned
Turn real-time scanning on or off
Switch each site-wide fix on or off, and set the focus outline color and the skip link’s target
Choose whether plugin data is removed on uninstall
Built to the standard it enforces
The plugin’s own admin screens and Block Editor panel are audited against the same WCAG 2.2 AA and Section 508 rules the scanner checks your content for: full keyboard operability, visible focus states, correctly associated form labels, non-skipping heading structure, and severity information that is never color-only.
Free vs. Pro
Everything in this readme so far — all 57 checks, all 7 one-click fixes, all 12 site-wide fixes, unlimited posts on unlimited sites — is completely free, forever, with no license required. Pro is genuinely separate functionality on top of it, mainly around scanning content the free plugin doesn’t reach at all, and automating what you’d otherwise do by hand:
[Pro] 8 additional accessibility checks (65 total)
[Pro] Choose your compliance standard: WCAG 2.2 Level AA, Section 508, or the EU’s European Accessibility Act — rules that don’t apply under your chosen standard are skipped and hidden from the reference list
[Pro] Full-site scanning: widgets, menus, theme templates, taxonomy terms, shortcode output, your theme’s own CSS, WooCommerce products, EDD downloads, and any custom post type
[Pro] “Fix All Safe Issues” bulk auto-fix in one batch, with a full undo log
[Pro] 4 more site-wide fixes: file type & size on download links, missing page titles, labels for every unlabeled form field (including other plugins’ forms), and restricting PDF uploads
[Pro] Live, on-canvas issue markers right inside the Elementor editor
[Pro] A front-end accessibility checker with on-page markers and a screen-reader simulator
[Pro] A visitor-facing accessibility toolbar (text size, contrast, underlining, focus visibility)
[Pro] Scheduled scans with email digests
[Pro] VPAT / ACR report generation and Excel export
[Pro] WooCommerce product image alt-text audit across your whole catalog
[Pro] Multisite network-wide compliance rollup
[Pro] REST API, WP-CLI, and webhooks
[Pro] White-label branding for agencies
[Pro] Priority support
Every Pro tier unlocks that exact same list — Professional, Small Business and Agency differ only in how many sites one license covers, so pick based on how many sites you manage. See current pricing and get ADA Compliance & Accessibility Checker – WCAG 2.2, Section 508 Pro →
