If you are about to buy an accessibility checker tool, the single biggest mistake is buying an overlay or widget and assuming it makes your store ADA compliant. It does not. Courts have repeatedly ruled against stores that relied on overlays, and the FTC has gone after at least one major vendor (accessiBe) for misleading claims. Before you spend a dollar, you need a checker that scans your real HTML against WCAG 2.1 AA (the legal floor) and ideally WCAG 2.2 AA (the 2026 best practice), and a fixer that changes the underlying code, not a JavaScript layer painted on top.

This article walks through the nine mistakes WooCommerce store owners make when they go to buy an accessibility checker tool, in the order they usually happen. If you avoid these, you will end up with a tool that actually reduces your legal risk instead of one that just makes a dashboard look green.

Quick answer

The most expensive mistakes when buying an accessibility checker tool are: choosing an overlay, trusting the vendor’s own “compliance score,” buying a generic WordPress plugin that ignores WooCommerce templates, skipping a WCAG 2.2 check, and paying a yearly subscription before you have audited a single page. A good checker scans against WCAG 2.1 AA and 2.2 AA, flags the specific success criterion (for example, 1.1.1 Non-text Content, 1.4.3 Contrast, 2.4.7 Focus Visible), and either fixes the code or tells you exactly where in the theme to fix it.

Why this matters in 2026

A few numbers to set the stakes:

  • Between 5,114 and 8,667 ADA digital accessibility lawsuits were filed in the US in 2025, depending on whether you count state cases.
  • That is roughly a 20% increase year over year.
  • 95.9% of home pages tested in the WebAIM Million 2026 study had detectable WCAG 2 failures.
  • The European Accessibility Act (EAA) became enforceable on June 28, 2025, and applies to any WooCommerce store selling to EU consumers. Its technical standard is WCAG 2.1 AA (via EN 301 549).
  • Average settlement cost for a US ADA web lawsuit hovers around $25,000, not counting remediation.

Buying the wrong checker does not just waste your subscription fee. It leaves you exposed to all of the above while you think you are protected.

Mistake 1: Buying an overlay and calling it compliance

Overlays (the floating accessibility icon in the corner) are JavaScript widgets that try to patch your site at runtime. They do not change your HTML. Screen reader users frequently report they make things worse, and there is a well-documented track record of stores using overlays still getting sued.

If a tool’s main value proposition is “install one line of code and become compliant,” that is a red flag. Real fixes happen in the theme files, the product templates, and the checkout markup, not in a widget.

Mistake 2: Trusting the vendor’s own “compliance score”

Many checkers display a score out of 100 and a green checkmark. Those scores are almost always calibrated by the vendor and bear no relationship to how a court or the DOJ would evaluate your site.

What to look at instead:

  • Does the report cite the specific WCAG success criterion for each issue (e.g., 1.1.1, 1.3.1, 1.4.3, 2.1.1, 2.4.7, 3.3.2, 4.1.2)?
  • Does it tell you the conformance level (A, AA, AAA)?
  • Does it produce a PDF or HTML audit report you can hand to a lawyer or developer?

If the answer to any of those is no, the tool is selling reassurance, not compliance.

Mistake 3: Buying a generic WordPress plugin that ignores WooCommerce

This one bites WooCommerce owners specifically. Most WordPress accessibility plugins were built for blogs and brochure sites. They will check your post titles and contact form, but they will not look inside:

  • The product loop on shop archive pages
  • Variation swatches and add-to-cart buttons
  • The cart and checkout templates
  • Order received and account pages
  • WooCommerce-generated notices and error messages

If the checker does not understand woocommerce_template_loop_product_title or where add-to-cart buttons are rendered, it will miss the issues most likely to show up in a lawsuit (carts and checkouts are the favorite plaintiff targets).

Mistake 4: Skipping the WCAG 2.2 check

WCAG 2.1 AA is the legal floor. WCAG 2.2 AA is the 2026 best practice. The difference matters because 2.2 added nine new success criteria, several of which hit ecommerce hard:

  • 2.4.11 Focus Not Obscured - the focus indicator must not be hidden behind sticky headers or cookie banners.
  • 2.5.7 Dragging Movements - anything draggable needs a single-pointer alternative (relevant for slider product galleries).
  • 2.5.8 Target Size (Minimum) - interactive controls must be at least 24x24 CSS pixels.
  • 3.3.7 Redundant Entry - do not make the buyer retype the same info during checkout.
  • 3.3.8 Accessible Authentication - no cognitive function tests for login.

A checker that only tests against 2.1 will give you a clean bill of health on a store that is already behind the 2026 standard. Ask the vendor directly: “Which version of WCAG does this scan against, and can I see a 2.2-specific report?”

Mistake 5: Paying for a year before scanning a single page

Most accessibility tool vendors push annual billing. Do not commit until you have:

  1. Run a free scan on your highest-traffic product page.
  2. Run a free scan on your cart page.
  3. Run a free scan on your checkout page.
  4. Read the resulting report and confirmed it actually identifies real issues with real WCAG references.

If the free scan returns only generic warnings (“images may be missing alt text” without telling you which images), the paid version is unlikely to be more specific. The Accessibility Checker Tool: Step-by-Step Buying Guide walks through this evaluation process.

Mistake 6: Ignoring batch scanning when you have hundreds of products

A single-page checker is fine for a brochure site. If you sell 200 products, each with 5 images and 3 variations, scanning one page at a time is a multi-week project. By the time you finish, your earliest fixes are stale.

What to require:

  • Batch or site-wide scanning that crawls all product, category, cart, and checkout URLs.
  • A queue or scheduler so scans run overnight, not in your browser tab.
  • A change log so you can see whether last month’s fixes held.

Mistake 7: Buying a checker with no fixer

A checker tells you what is wrong. A fixer changes the code. If you only buy the checker, you still need a developer (or yourself, with developer skills) to act on every issue. For a 50-product WooCommerce store with thousands of images, that is dozens of hours.

Look for tools that can auto-fix the safe, deterministic stuff:

  • Missing lang attribute on <html>
  • Empty button text on icon-only buttons
  • Missing ARIA labels on standard WooCommerce form fields
  • Skip links
  • Programmatic focus indicators
  • Link-distinguishing text where the URL and label disagree

These fixes are mechanical. You should not be paying a human to do them.

Mistake 8: Trusting auto-fix for judgment calls

The other side of the coin: do not let any tool auto-write your alt text and walk away. AI-generated alt text for a product image (“A product image” or “Red shirt on white background”) is not the same as meaningful alt text (“Men’s slim-fit cotton T-shirt in burgundy, model wearing size M”). For 1.1.1 Non-text Content, the alt text has to convey the purpose of the image in context.

The honest position: automated tools handle the mechanical 70 to 80% well. The remaining 20 to 30% (meaningful alt text, complex form flows, dynamic error messages, custom checkout steps) needs human review. Any vendor that claims 100% automated compliance is lying.

Mistake 9: Buying without a re-scan plan

A WooCommerce store changes constantly. New products, new theme updates, new plugins, new payment integrations. A single audit in January is worthless by June if you have not rescanned.

Before you buy, ask:

  • Does the tool scan automatically on a schedule?
  • Does it alert you when new issues appear?
  • Does it track regressions, so a fix in March that breaks in May actually surfaces?

If re-scanning is a manual button click, you will forget.

A 10-minute checklist before you click buy

Use this before committing to any accessibility checker tool subscription:

  1. Confirm it scans against WCAG 2.1 AA and 2.2 AA, not just 2.0.
  2. Run a free scan on a product page, cart, and checkout.
  3. Verify each issue cites the specific WCAG success criterion number.
  4. Confirm it understands WooCommerce templates (loops, variations, cart, checkout).
  5. Check for batch scanning if you have more than 25 products.
  6. Check whether it can auto-fix safe issues vs only reporting them.
  7. Confirm it produces a PDF or shareable compliance report.
  8. Verify there is a monthly billing option, not just annual.
  9. Confirm scheduled re-scans and regression alerts.
  10. Make sure it is not an overlay.

If the tool fails on more than two of these, keep looking.

How AmazingPlugins helps

The AmazingPlugins WooCommerce Accessibility Fixer is built for exactly the mistakes above. It is a WordPress plugin that hooks into WooCommerce templates directly. It is not an overlay. It scans your product pages, cart, checkout, and account templates and writes fixes into the markup where it can do so safely.

What it handles automatically:

  • Alt text scaffolding for product images (with a review queue, because meaningful alt text needs your eyes)
  • Keyboard navigation and visible focus indicators on add-to-cart and variation controls
  • ARIA labels on WooCommerce form fields
  • Color contrast issues flagged with specific suggested values
  • Skip links to main content and product listings
  • Empty button text on icon-only buttons (close, quantity controls, etc.)
  • lang attribute on the HTML root
  • Link text that distinguishes destination from generic “read more” labels
  • Accessible input names on every form field

Pro adds batch scanning across the whole catalog, auto-fix mode for the deterministic issues, a PDF compliance report you can hand to a lawyer or auditor, and priority support. You still need to review judgment calls (meaningful alt text for unique products, custom checkout flows), but the mechanical work is done for you.

If you are still comparing options or want to understand what an honest accessibility-checker purchase looks like, the Accessibility Checker Tool: Step-by-Step Buying Guide breaks down the evaluation process in more detail.

Frequently asked questions

Is a free accessibility checker enough to be compliant?

A free checker can identify most of the easy WCAG failures on a single page. It is not enough for a multi-page WooCommerce store with hundreds of products, and it will not produce a court-ready audit report. Use a free scan to confirm a paid tool is worth buying, not as your compliance plan.

What is the difference between an accessibility checker and an accessibility fixer?

A checker scans your site and tells you what is wrong, citing WCAG criteria. A fixer changes the underlying code (HTML, ARIA, CSS) to resolve the issues. Many tools are checkers only, which leaves the actual remediation work on you or your developer. The AmazingPlugins WooCommerce Accessibility Fixer does both.

Does buying an accessibility checker tool protect me from ADA lawsuits?

No single tool protects you. Buying a checker that actually identifies WCAG 2.1 AA and 2.2 AA issues, fixing what it finds, posting an accessibility statement, and maintaining the fixes through re-scans is what reduces your legal risk. A checker is the first step, not the whole answer.

How much should an accessibility checker tool cost?

Reasonable WooCommerce-focused tools run anywhere from $99 to $500 per year for a single store, depending on scan depth, batch scanning, and auto-fix capability. Tools priced under $50 a year are usually checkers only with limited WooCommerce awareness. Tools priced over $1,000 a year that are not service-tier audits are usually overpriced overlays or enterprise software you do not need.

What WCAG version should the tool check against in 2026?

WCAG 2.1 AA is the legal floor in the US (DOJ guidance) and the EU (EAA via EN 301 549). WCAG 2.2 AA is the 2026 best practice and adds the focus, target-size, and authentication criteria that ecommerce sites trip on most. Buy a tool that checks against both.
