"The Sample

The million home page list was derived from the Tranco ranking which combines several sources of "top" web sites.

Sites without home pages, pages that returned errors (404, etc.), pages with fewer than 10 HTML elements, and pages with more than 5,000 links to the same domain (for SEO purposes) were not included.

Methodology

The WAVE accessibility engine was used to analyze the rendered DOM (Document Object Model) of all pages after scripting and styles were applied. WAVE detects end-user accessibility barriers and Web Content Accessibility Guidelines (WCAG) 2.2 A/AA conformance failures. All automated tools, including WAVE, have limitations—not all conformance failures can be automatically detected. Absence of detected errors does not indicate that a page is accessible or conformant. Although this report describes only a subset of accessibility issues on only 1,000,000 home pages, this report provides a quantified and reliable representation of the current state of the accessibility of the most influential pages on the web.

Detected Errors

Across the one million home pages, 56,114,377 distinct accessibility errors were detected—an average of 56.1 errors per page. The number of detected errors increased 10.1% since the 2025 analysis which found 51 errors/page. "Errors" are WAVE-detected accessibility barriers having notable end user impact, and which have a very high likelihood of being WCAG 2.2 Level A/AA conformance failures.
