Borderline visible. AI bots can crawl HTML5 accessibility, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

About HTML5 accessibility

from our crawl and measurement

"This includes if they are keyboard accessible, mapped to the platform accessibility APIs, and if any accessibility related features are supported." That is how HTML5 accessibility introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.7 out of 10.

Our crawl found a readable heading structure. It is missing structured data describing the business, an llms.txt file and a sitemap.

What this score means

Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 4.9/10, HTML5 accessibility is crawlable but under-signaled - fixable, and the signals above are where to start.
