A B2B website accessibility audit is a structured review of the paths people use to learn, compare, and convert. It should help a team find barriers, record evidence, and verify repairs across templates—not just produce a scanner score. Accessibility problems can appear in navigation, content, forms, media, and shared components, so a useful review covers both individual pages and complete tasks.
Start with a clear distinction: quick checks are useful for finding obvious issues, but they do not prove that a site conforms to an accessibility standard. W3C’s WAI explains that automated tools cannot determine accessibility by themselves and that knowledgeable human evaluation is required. For a formal conformance evaluation, use a defined methodology and target; use this workflow as a practical review and prioritization guide.
1. Scope the site by templates and important tasks
List the main page types and the journeys that matter: find a solution, compare options, review technical fit, submit a request, or contact support. Include shared components such as the header, navigation, cookie notice, forms, and footer. A representative review of templates is an efficient way to locate recurring problems, but it is not a full site-wide conformance claim. Expand the sample when a template, component, or interaction differs.
Agree on the evaluation target, browsers, assistive technology, and reporting format before testing. W3C’s accessibility evaluation resources distinguish initial checks, evaluation tools, human review, and the WCAG-EM methodology for assessing conformance. Keep the scope and limitations in the report so a quick review is not mistaken for certification.
2. Combine automated checks with hands-on review
Automated tools can flag patterns such as missing accessible names or contrast concerns, but a flagged result needs human interpretation and many interaction problems require manual testing. Run an agreed checker on representative templates, then review the actual page in a browser.
- Use the keyboard to reach and operate navigation, menus, links, dialogs, and form controls; check that focus is visible and moves in a sensible order.
- Inspect headings, page title, landmarks, link names, and image alternatives. A visual heading is not necessarily a semantic heading.
- Test forms from start to finish: labels, instructions, required fields, error messages, correction, and successful confirmation.
- Check readable zoom and responsive layouts, contrast, motion, captions, and whether important information is conveyed only by color or imagery.
W3C’s Easy Checks are explicitly an initial review, not a complete accessibility evaluation. Use them to start a conversation and identify visible barriers; use deeper testing to understand how the whole task works.
3. Include people who use the site differently
A standards review and a real task session answer different questions. W3C recommends involving users with disabilities during evaluation; their experience can reveal usability issues that a conformance review alone does not find. Ask participants to complete realistic tasks on a prototype or live page, observe where they need help, and record what assistive technology and setup were used.
Do not treat one person as representative of every disability or assistive technology. Choose participants based on the audience and tasks, and combine their feedback with expert review. W3C’s guidance on involving users in accessibility evaluation describes how to use feedback at different stages of design and development.
4. Prioritize barriers by user impact and reach
A raw list of findings does not tell a team what to fix first. Use a simple triage heuristic: does the issue block a critical task, how many templates or users may it affect, and is there a reliable workaround? This is a planning aid, not a WCAG score. Give blockers in high-value tasks immediate attention, then look for shared-component fixes that remove the same issue across many pages.
- Record the page or component, task, barrier, steps to reproduce, browser and assistive technology, and supporting evidence.
- Describe the user impact in plain language, such as “keyboard user cannot open the product menu” or “screen reader user cannot identify the required field.”
- Assign an owner, target release, and retest criteria; link related findings to the shared component or template.
- Separate a verified fix from a proposed workaround, and explain any remaining limitation.
W3C’s implementation guidance recommends evaluating early and regularly, recording findings in a standard report, and integrating issues into ordinary quality assurance. See the WAI guidance on implementing accessibility work for that ongoing process.
5. Verify repairs across the whole journey
After a fix, retest the affected page and other templates that use the same component. A corrected button style may improve every page; a local patch might leave the same problem in a mobile menu or embedded form. Include content updates and CMS patterns in the review, not only code changes.
Add the most important checks to design reviews, component acceptance criteria, content publishing guidance, and the go-live process. The existing B2B website design-system guide covers component governance; the website go-live checklist connects page QA to the buyer journey.
What an audit can and cannot tell you
A practical review can identify concrete barriers and establish a prioritized repair queue. It cannot promise a fixed conversion increase, and a quick scan cannot establish conformance. If a business needs a formal WCAG conformance statement, define the applicable target and use a qualified evaluation process. The purpose of ongoing accessibility work is to make real tasks usable for more people and to prevent known barriers from returning.

Treat the audit as a repeatable practice: scope real tasks, combine automated and human checks, involve users, assign evidence-based fixes, and retest the experience after changes.
