Crawler Vision

What it is

Crawler Vision is a website analyzer from Techtonic Systems that checks how easily search engine bots and AI platforms can reach and understand a page. You enter a URL, the service fetches the HTML or renders the JavaScript with its RENDERED engine, and it evaluates more than 50 signals across technical SEO, meta tags, structured data, AI files such as robots.txt and llms.txt, and local SEO. The result is a composite Crawler Vision Score plus a ranked list of recommendations. Premium checks look at whether ChatGPT, Gemini, Perplexity and Grok mention your brand. It suits site owners, SEO specialists and teams running React, Vue or Angular sites.

Editor's notes

More context from AI BirdView

What we like about Crawler Vision is that it treats AI assistants as a real audience for your website, right next to classic search crawlers. Instead of a long, flat checklist, it rolls dozens of signals into a single score and then tells you which fixes matter most. That makes it a quick way to see whether a JavaScript-heavy page is actually readable by the bots you care about.

The free tier gives you 20 credits that restore automatically, and a standard analysis costs one credit, so you can test pages without creating an account.
The RENDERED engine runs JavaScript before analysis, which helps single page apps see what crawlers really receive.
It checks for AI-oriented files like llms.txt and ai.txt alongside robots.txt and sitemaps.
Premium LLM visibility checks look at whether ChatGPT, Gemini, Perplexity and Grok mention your brand.
Reports export as Markdown for people or as a context file meant for pasting into an LLM.

Crawler Vision is a good fit for marketers, founders and developers who want a fast health check on discoverability before investing in a bigger SEO platform. A practical tip: run your homepage and one deep content page, since template issues often show up only on inner pages, and compare the two scores before deciding what to fix first.
