Before buying an accessibility widget or overlay, review the actual tasks people need to complete on your website. Automated tools can identify some problems, but no single tool can determine whether a site is accessible. You need a mix of automated checks, human review, and testing of real interactions.
That is not an argument against tools. It is a way to give each tool the right job.
Start with the pages that carry consequences
Choose a representative set instead of scanning only the homepage. Include the main navigation, a content page, a service or product page, a form, and any checkout, login, booking, or account path that matters.
Write down what a person must be able to do on each page. Someone should be able to find the heading, understand the content, operate controls, complete the form, recognize errors, and know whether the action succeeded.
Run a small set of direct checks
The W3C Web Accessibility Initiative's Easy Checks covers useful starting points such as page titles, text alternatives, headings, contrast, text resizing, keyboard access, visible focus, form labels, errors, multimedia alternatives, and basic structure.
You can learn a great deal by using only the keyboard. Can you reach every interactive control? Is focus visible? Does the order make sense? Can you open and close menus, dismiss dialogs, and submit a form without a mouse?
Resize the text, inspect meaningful images for appropriate alternatives, and review form labels and error messages. These checks will not establish full conformance, but they expose whether basic barriers are being treated as real product defects.
Understand what automation cannot decide
An automated scanner can detect a missing label or certain contrast problems. It may not know whether alt text communicates the purpose of an image, whether a heading describes the section, whether instructions make sense, or whether a custom interaction is understandable with assistive technology.
W3C's evaluation overview states that tools help with evaluation but cannot determine accessibility on their own; knowledgeable human evaluation is required. A score or badge should not replace the underlying work.
Ask vendors for evidence, not a promise
If you are considering a widget, overlay, scanner, or audit service, ask:
- Which barriers does the product detect or change?
- Which parts require manual review or code/content repair?
- How does it work with keyboard and assistive-technology users?
- What happens when the site, theme, or forms change?
- Can you see the findings and remediation record?
- Does the vendor promise legal compliance or universal access beyond what it can demonstrate?
Do not treat this article as legal advice or as a conformance audit. Accessibility obligations vary by context and jurisdiction, and a qualified accessibility or legal professional should review higher-risk requirements.
Fix the source and retest the task
Prioritize barriers that block navigation, understanding, forms, purchases, and other core tasks. Fix the content, markup, styling, or interaction at its source where possible, then repeat the same task and record the result.
Accessibility belongs in ongoing site work, not only a launch checklist. Add representative checks to the WordPress maintenance calendar and repeat them after meaningful design or plugin changes. If you need help separating a design defect from a content or technical defect, contact TechDex with the page and task that is failing.
