Page Comparison
Compare accessibility audit results between two pages or two versions of the same page.
What is Page Comparison?
Page Comparison lets you run audits on two different URLs and compare the results side by side. This is useful for tracking accessibility improvements over time, comparing staging vs. production, or comparing two similar pages (e.g. different language versions).
Common use cases
📈
Track improvements
Compare the same page before and after accessibility fixes to measure progress.
🔬
Staging vs. production
Verify that your staging environment matches production accessibility standards before deploying.
🌍
Multi-language pages
Compare accessibility across different language versions of the same page.
🧪
A/B testing
Compare accessibility between two design variants to choose the more accessible option.
How to run a Page Comparison
- 1
Open the audit form
Click New Audit from the dashboard.
- 2
Enable "Compare Pages"
Toggle on the Compare Pages option. A second URL field will appear.
- 3
Enter both URLs
Enter the Page A URL (baseline) and the Page B URL (comparison). Both pages will be audited with the same settings.
- 4
Choose engines and standard
Select your audit engines and compliance standard. The same settings apply to both pages.
- 5
Click Run Comparison
Both pages are audited. Results are displayed in a side-by-side comparison view.
Reading comparison results
The comparison view shows:
Summary cards
Side-by-side violation counts for Page A and Page B, broken down by severity (Critical, Serious, Moderate, Minor).
Issues only in Page A
Violations present in the baseline page but not in the comparison page — these are regressions fixed in Page B.
Issues only in Page B
Violations present in the comparison page but not in the baseline — these are new regressions introduced in Page B.
Issues in both pages
Violations present in both pages — these are shared issues that need to be fixed in both.
Exporting comparison reports
After a page comparison, you can export:
- →Comparison Report DOCX — side-by-side violation summary with diff analysis
- →HTML Report — interactive comparison with filtering by page
- →Individual reports — separate VPAT or Error Report for each page
💡 Pro tip: Track progress over time
Save your audit results and use Page Comparison to compare the current version of a page against a previous audit. This gives you a clear picture of accessibility improvements sprint over sprint.
Comparison with authentication
Page Comparison supports all authentication modes:
- →Both pages can use the same authentication (e.g. same session cookies)
- →Or each page can use different authentication settings if needed
- →See Authenticated Page Auditing for setup instructions
