A proper website accessibility audit rarely starts with a scanner tool spitting out a color-coded report. It starts with someone navigating the website like an actual visitor sf website design, which sounds obvious until you realize how often that step gets skipped entirely.

What Auditors Do Before Writing the Report
An auditor typically starts with a site crawl, mapping out templates and page types rather than checking every single URL individually. A blog with hundreds of posts doesn't need eight hundred manual reviews. It needs its five or six underlying templates checked properly, since most issues appear repeatedly across pages using the same layout.
Keyboard-only navigation gets checked near the beginning of the audit. Mouse aside, can every interactive element be accessed and operated entirely through keyboard controls? Dropdown menus, modal popups, and custom sliders cause accessibility problems on more websites than many developers realize, mostly because developers build them visually first and add keyboard support as an afterthought, if at all.
Severity Ratings Aren't All Equal
Not every finding carries the same weight. A missing alt tag on a decorative background image barely matters. A missing label on a checkout form's payment field can make it extremely difficult for a screen reader user to complete the transaction. Good audits sort findings by actual impact, not just by how many instances of an issue show up in a scan.
Some auditors dump three hundred flagged items into a spreadsheet with zero prioritization. That's not helpful. It's overwhelming, and it usually gets a business nowhere because the team has no clear idea which problems should be addressed first.
A Good Accessibility Report Should Be Actionable
A finding that says "color contrast is insufficient, element 4.2.1" without supporting imagery and a straightforward explanation forces a developer to spend time figuring out what the finding actually refers to. Good documentation includes the affected element, relevant screenshot, applicable WCAG success criterion, and a practical remediation recommendation, written in language a developer can act on without decoding legal jargon first.
Retesting after fixes matters too. Skipping that step is like having dental work completed and never checking whether the repair remained effective. Sometimes fixes create unintended accessibility issues, and only a follow-up review catches that.
