Every page and site in A11y Pulse has an accessibility score between 0 and 100. The score gives you an at-a-glance summary of how accessible your pages are, and lets you track progress over time.
How the score is calculated
Each page starts at a perfect score of 100. Points are then deducted for every accessibility issue found on that page, based on the severity of the issue:
| Severity | Points deducted |
|---|---|
| Critical | 20 |
| Serious | 15 |
| Moderate | 5 |
| Minor | 2 |
A page’s score cannot go below 0, no matter how many issues are found.
A site’s score is the average of the scores of all of the pages monitored on that site, rounded to the nearest whole number.
Score ranges
Scores are grouped into three ranges, each with its own colour in the A11y Pulse dashboard:
- Good (90–100): Your page has few or no accessibility issues. Keep an eye on this score to catch regressions.
- Needs Improvement (70–89): Your page has some issues that should be addressed. Focus on fixing critical and serious issues first.
- Poor (0–69): Your page has significant accessibility issues. We recommend prioritising fixes here to make your site usable for more visitors.
What affects your score
Only confirmed accessibility violations affect your score. The following do not count against your score:
- Issues you have ignored using the Ignored Audits feature.
- Audits that could not be run automatically and require manual review.
- Audits that are not applicable to the page being scanned.
Because of this, ignoring issues that are false positives or deliberate exceptions is a legitimate way to get a more accurate score for your site.
