Accessibility audit
The evaluation of a site against accessibility criteria. It combines automated tests and manual review.
An accessibility audit measures the gap between a site and a standard such as WCAG 2.2 AA. It identifies issues, explains them and ranks them by impact.
Automated and manual
Automated tests quickly detect a meaningful share of issues (contrast, missing alternatives, form labels). A manual review remains necessary for criteria that require human judgement, such as whether a text alternative is relevant or whether navigation is logical.
Frequently asked questions
How long does an accessibility audit take?
The duration depends on the number of templates to examine, not on the number of pages. A site that repeats fifteen page templates is audited faster than a site of fifteen entirely different pages. Automated tests are immediate, manual review is what takes time.
How often should it be redone?
An audit describes a site at a given moment. Every redesign, every new user journey and every component change can introduce new gaps. Continuous checking at each release costs less than a repeated full audit.
