Accessibility audit

What is an accessibility audit?

An accessibility audit is a structured review of a website or app to find the barriers that stop disabled people from using it. The benchmark is almost always the Web Content Accessibility Guidelines (WCAG), graded at levels A, AA, and AAA, with AA being the standard most laws and contracts expect. An audit checks a product against those success criteria and reports what passes, what fails, and how serious each failure is.

A real audit combines two kinds of testing. Automated tools scan code for issues like missing alt text, low colour contrast, or unlabelled form fields, and they catch maybe a third of problems quickly. The rest needs manual testing: navigating the whole site with a keyboard, listening to it through a screen reader, checking that focus order makes sense and that error messages are announced. An audit that finds a checkout form is impossible to complete without a mouse is exactly the kind of barrier automated scans tend to miss.

The output is a prioritised list of issues mapped to specific WCAG criteria, with enough detail for developers to fix each one. An audit is a snapshot, not a guarantee. Accessibility holds only if the team keeps testing as the product changes, which is why audits work best as a repeated practice rather than a one-time certificate.

Accessibility audits at Dallonses

We treat accessibility as part of building software well, not a box to tick before launch. When a client comes to us with WCAG compliance on the line, we run the audit properly: automated scans for the obvious failures, then manual passes with a keyboard and screen reader for everything the tools can't see. We hand back a list ranked by impact, not an undifferentiated dump of warnings.

Where we add the most value is fixing what the audit finds and keeping it fixed. Our accessibility testing and inclusive design work feeds straight back into development, so the corrections land in the codebase rather than a PDF. We bake the checks into how the product gets built going forward. Accessible websites stay accessible when accessibility is a habit, and that is what we set up.

Worried your product locks people out? Let's find out where, and fix it.
