Check Accessibility Audits

---

Accessibility audits are a set of limited accessibility checks performed by Lighthouse to ensure that a page meets selected accessibility criteria. They are available for each Snapshot test, unless a test has been completed with partial results due to an error.

The Accessibility audit category receives a score between 0 and 100, visible at the top of the audit section. Higher grading implies (but doesn’t guarantee) better accessibility. Accessibility audits are limited and the use of dedicated, accessibility testing tools as well as manual testing is recommended.

Accessibility audit structure

Accessibility audits fall into the following categories:

• Opportunities
• Diagnostics
• Passed audits

To ensure passing Lighthouse Accessibility audits, it’s essential to focus on the Opportunities and Diagnostics categories, outlining possible improvements to a given page. Each audit item includes:

• Title (e.g.: [accesskey] values are unique)
• Audit description (e.g.: Access keys let users quickly focus a part of the page. For proper navigation, each access key must be unique.)
• Additional details (optional, e.g.: list of HTML elements affected)

If an audit item features a table with more details, the table can be sorted by clicking on the column name.
