U.S. Government Website Quality Dashboard
Daily automated accessibility and performance scans of the top 100 most-visited U.S. government URLs, powered by Google Lighthouse and axe-core.
What is DAP?
The Digital Analytics Program (DAP) is a U.S. government analytics service that tracks website traffic across hundreds of participating federal agencies. It measures page views, visitor counts, and usage patterns for government websites, providing transparency into how the public engages with federal digital services. The traffic data is publicly available at analytics.usa.gov.
This dashboard uses DAP traffic data to identify the most-visited government URLs and measures their quality daily. Each scan covers:
- Accessibility — WCAG compliance measured by Lighthouse and axe-core (0–100, higher is better)
- Performance — Page load speed including Core Web Vitals (0–100, higher is better)
- Best Practices — Modern web development standards (0–100, higher is better)
- SEO — Search engine optimisation fundamentals (0–100, higher is better)
Scans run daily. Click any report date below to see detailed per-URL findings, accessibility patterns, and trend analysis. View the source code on GitHub.
