FAQ
General
Does ClearSight check for WCAG 2.2? Not yet. ClearSight currently covers WCAG 2.1 Level A and AA. WCAG 2.2 support is on the roadmap.
Is a perfect score of 100 achievable? Yes, but a score of 100 doesn’t mean your site is fully accessible. Automated tools only catch 30–40% of all accessibility issues. Manual testing with screen readers and other assistive technology is still necessary.
Does ClearSight scan mobile views? Not currently. Scans use a desktop viewport. Mobile-specific issues may not be detected.
Scanning
Can ClearSight scan pages behind a login? No. ClearSight can only scan publicly accessible pages. Authentication support is planned.
Does ClearSight respect robots.txt? No. ClearSight scans all pages it can reach regardless of robots.txt directives.
Why did my crawl find fewer pages than expected?
If your site is a JavaScript SPA, the crawler may miss pages that are only accessible through client-side navigation. The crawler uses lightweight HTTP discovery, not a full browser, for the page discovery phase. Try adding a /sitemap.xml to your site to help the crawler find all pages.
How often should I run a crawl? For active sites, weekly or after major deployments. For static sites, after any content changes.
Results
Why is my score lower than I expected? Severity penalties add up quickly. A single Critical issue removes 10 points. Check for Critical and Serious issues first — fixing those will have the biggest impact on your score.
Why are some issues marked “Potential”? Potential issues are cases where automated testing can’t be certain a violation exists. They need human review. See Confirmed vs Potential Issues.
I dismissed an issue but it came back. Why? Dismissals are matched by issue fingerprint (element selector + rule + page URL). If the element’s HTML structure changed, the fingerprint changed, and it appears as a new issue. Re-dismiss it if it’s still a false positive.
Technical
Which browsers does ClearSight scan in? ClearSight uses headless Chromium (via Playwright). Results may differ from Firefox or Safari.
Which WCAG rules does ClearSight check? All axe-core rules for WCAG 2.1 Level A and AA, plus custom engines for link text quality and touch target sizes. See the axe-core Rule Index.
