An audit is a detailed review of a website or application against the Web Content Accessibility Guidelines (WCAG). It identifies the barriers people encounter, and explains how to remove them.

It depends on the size of the product and the number of unique samples. Most audits take between two and four weeks from the start of testing to the delivery of the report.

You get a report which lists each issue, the people it affects, the guidelines it relates to, and a recommendation for how to fix it.
