Siteimprove performs a combination of automated and semi-automated accessibility checks in reference to a selection of Web Content Accessibility Guidelines (WCAG) success criteria.
Your Accessibility Score is a measure of how well your site performs against the automated Siteimprove accessibility checks.
Your Accessibility Score contributes to your overall Digital Certainty Index™ (DCI™) Score.
The Accessibility Score can be accessed on the Accessibility Overview page for a selected site.
Is the Accessibility Score a compliance score?
No. WCAG compliance cannot be measured with automated checks alone, therefore, your Accessibility score does not represent how compliant your website and its content are with regards to WCAG.
Automated accessibility testing is an integral and strategic method for maintaining an accessible web presence. A large number of techniques used to measure WCAG success criteria can be automated.
Additionally, manual testing carried out by experts is required to accurately measure WCAG compliance.
How do I improve my Accessibility Score?
You can improve your Accessibility Score by earning points for fixing issues that belong to one of the three issue categories listed under “Score details”:
- No automatically detected Errors
- No automatically detected Warnings
- Proportion of pages with low Error rate
Points can be earned by resolving issues on a per page basis.
What do the Accessibility Score categories mean?
Errors: automatically determined failures to meet success criteria in the Web Content Accessibility Guidelines (WCAG).
Warnings: automatically determined failures to meet best practices in the Web Content Accessibility Guidelines (WCAG).
Proportion of pages with low Error rate: number of pages with a single Error or Warning.
What is the Accessibility Score weighting for each issue category?
|Pages with low Error rate||Medium|
What does the Accessibility Score not include?
The Accessibility Score does not include issues categorized Reviews.
Reviews: Potential failures to meet best practices or success criteria in the Web Content Accessibility Guidelines (WCAG), which can only be verified with a manual inspection.
