A proper website accessibility audit rarely starts with a automated scanner generating 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.

The Work That Comes Before the Accessibility Report
An auditor typically starts with a site crawl, mapping out page templates and content types instead of manually reviewing every URL. A blog with hundreds of posts doesn't need a separate manual review of every article. 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. Without relying on a mouse, can every interactive element get reached and activated using just a keyboard? Dropdown menus, modal popups, and custom sliders cause accessibility problems on more websites than many developers realize, mostly because developers often create the visual interaction first and consider keyboard access later, if at all.
Not Every Accessibility Issue Has the Same Impact
Not every finding carries the same weight. A missing alt tag on a purely decorative image barely matters. A missing label on a checkout form's payment field can block a transaction entirely for someone using a screen reader. Good audits prioritize issues according to their real-world effect, not just by the number of times an automated scanner identifies the same issue.
Some auditors dump three hundred flagged items into a spreadsheet with zero prioritization. That's not helpful. It's difficult to manage, and it usually gets a business nowhere because nobody knows where to start.
Accessibility Reports Should Tell Developers What to Do
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 actual element, a screenshot, the specific WCAG success criterion involved, and a concrete fix, written in language a developer can understand and implement without having to interpret complicated legal terminology.
Retesting after fixes matters too. Skipping that step is like getting a cavity filled and never going back to confirm the filling actually held. Sometimes fixes introduce new problems nobody caught the first time around, and only a follow-up review catches that.
