AI Visibility Scorecard
HTML5 & CSS3
html5-css3.fr · Technology
Borderline visible. AI bots can crawl HTML5 & CSS3, 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 & CSS3
from our crawl and measurement
"Tutoriels HTML5 et CSS3 en français: géolocalisation, applications web offline, microdata, transformations 3D, dégradés, ombres et polices personnalisées." That is how HTML5 & CSS3 introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 3.5 out of 10.
Our crawl found structured data on the page (WebSite), a sitemap and a readable heading structure. It is missing an llms.txt file.

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 3.5/10, HTML5 & CSS3 is crawlable but under-signaled - fixable, and the signals above are where to start.
