Test how GPTBot, Claude, Perplexity, and 11 other bots see your website. Analyzes robots.txt, structured data, llms.txt, and content accessibility.
AI search engines like ChatGPT, Perplexity, and Gemini use their own web crawlers to index content. Each bot has a unique user-agent, and many websites accidentally block them through robots.txt rules written for traditional search. An AI crawl check audits your site against 14 known AI bot user-agents, identifies which ones are blocked, and flags missing structured data and llms.txt files that help AI models understand your content. Without this visibility, your site may be invisible to AI search results even if it ranks well on Google.
HEAD requests as Googlebot, GPTBot, Claude-Web, PerplexityBot, CCBot, and more.
Parse allow/disallow rules per bot, sitemap directive, and crawl-delay.
JSON-LD extraction: Article, FAQPage, Organization, Product, BreadcrumbList.
Check for the emerging standard that helps AI understand your site.
Most crawl checkers stop at robots.txt. We score what actually determines whether AI systems cite you: structured data quality, llms.txt presence, and content accessibility. This methodology comes from our own work optimizing for AI search.
Do AI browse bots (GPTBot, Claude-Web, PerplexityBot) have access? Is there a deliberate policy for training crawlers? A smart robots.txt isn’t just allow/block. It’s a strategy.
JSON-LD is how machines understand your content. We check for page-type-appropriate schema: Organization for homepages, Article for posts, BreadcrumbList for navigation, FAQPage for rich results.
The emerging standard that tells AI systems who you are, what you do, and how to cite you. We score structure, entity definitions, URLs, and use policy.
Can AI crawlers actually read your content without executing JavaScript? We check server-side rendering, title/description length, and framework detection.
This tool reflects what we learned optimizing pixelmojo.io for AI search. Every scoring criterion comes from real implementation and measurable results, not theory.
