Fractional CTO AI visibility check
Can ChatGPT, Claude, Perplexity, and Google read your site, and does it say anything specific enough to quote? Enter your homepage. The check reads it the way an AI crawler does and tells you what to fix first.
What the check looks at
- Readable without JavaScript
- How much text is in the HTML your server sends, and whether the page is an empty app shell.
- AI crawler access
- Whether robots.txt lets OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot, Googlebot, and Bingbot read your homepage.
- Not hidden from search
- Whether a meta robots tag or X-Robots-Tag header says noindex.
- Says who you help
- Whether the page names your role, an industry, a company stage, and the trigger events that make founders call you.
- Generic phrases
- How often the page uses phrases like "strategic partner" or "deep experience" that appear on almost every consultant site.
- Pages with specific content
- How many article, case study, or project pages your sitemap lists.
- Search basics
- Title, meta description, H1, and canonical link.
- llms.txt
- Shown for information only. It doesn't affect the result.
How the check works
Raw HTML, no JavaScript: the check reads the HTML your server sends, without running JavaScript. Google renders JavaScript, but in Vercel and MERJ's December 2024 analysis of crawler traffic, none of the major AI crawlers they tested, including OpenAI's and Anthropic's, rendered JavaScript.
Crawler names: the robots.txt check uses the user agents that OpenAI, Anthropic, Perplexity, and Google publish for search and answers, plus Bingbot. Training crawlers such as GPTBot and ClaudeBot are listed for information. Blocking them is your choice and doesn't remove you from AI search, according to OpenAI's and Anthropic's documentation.
Signals, not judgment: the niche and generic-phrase checks look for keywords. They show what they matched so you can judge for yourself. No AI model reads your site, and the check can't tell whether your claims are true.
Limits: passing every check doesn't guarantee that any AI tool will cite you or that you'll rank in search. The check only reads public pages and stops after 1.5 MB or 8 seconds. Sites behind bot protection may block it.
