How we checked
Each site was requested from outside a browser, using the stock TLS stack that GPTBot, ClaudeBot and PerplexityBot use. We record whether the handshake completes, what robots.txt permits, and whether the HTML that comes back contains readable text or an empty shell. A browser extension cannot run this check, because it inherits the browser’s own fingerprint and gets a clean answer from sites that refuse every non-browser client.
Positions and the agency list come from the live seo agency denver results on the date shown. Nothing on this page is a paid placement, and we make no claim about the quality of any agency’s work.
Common questions
How many Denver agencies can AI crawlers reach?
Of the 12 agencies checked for this page, 4 have a setup that stops at least one AI crawler from reading their site. Checked September 2, 2026.
What does this check actually measure?
Whether a non-browser client can complete a TLS handshake, whether robots.txt permits AI crawlers, and whether the page returns readable HTML or an empty shell that needs JavaScript. It runs outside a browser, which is the only way to see what a crawler sees.
Does being unreachable mean the agency is bad at SEO?
No. It means their own site is invisible to the crawlers behind AI answers, which is a different problem from ranking in Google. Most cases are a bot-protection rule or a JavaScript-rendered site, and both are quick to fix once found.
