Borderline visible. AI bots can crawl CSS Checker, 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 CSS Checker
from our crawl and measurement
"Lightweight browser extension that helps developers and designers instantly find and fix errors in their stylesheets. Free css validator, contrast checker, and xpath checker." That is how CSS Checker introduces itself. When AI engines look at it, they find little to work with. It scores 4.0 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.
AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic).

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 4/10, CSS Checker is crawlable but under-signaled - fixable, and the signals above are where to start.
