The premise
The web is being written by language models faster than the indexes can sort it. Some of that work is good. A lot of it is filler. Most readers cannot tell the difference at a glance, and most ranking signals do not yet draw the line. CrawlRanker draws it.
Every scan produces two things: an SEO audit graded against well-understood best practice, and an AI-automation score that reads how much of the page looks machine-generated. Both ship with confidence on every finding so you can tell the difference between a clear call and a coin flip.
What we are not doing
- Not a moderator. We do not flag sites, we do not report to hosts, we do not serve takedown requests. The scan exists on a public report URL and nowhere else.
- Not a judge of value. AI-generated content can be excellent. Human-written content can be terrible. The score reads automation, not quality.
- Not a plagiarism detector. The score is a fingerprint of the page itself — it does not compare against any other page or corpus.
Who built it
CrawlRanker started in late 2025 as a working answer to “how would I even tell?” — by then the daily question on every SEO forum. It shipped publicly in spring 2026.
The full methodology lives on the public methodology page. Every change to scoring is recorded with a date and a reason in the changelog.
How it is funded
During the public beta the scanner is free, with no signup, and there is no paid tier yet. The infrastructure cost — Anthropic API calls, hosting, the database — is funded out of pocket. A paid tier with deeper multi-page audits and exportable reports is on the near roadmap; the free single-URL scan will stay free.
We do not run ads, we do not sell scan data, and we do not partner with SEO toolchains that resell results. If that ever changes it will be announced before the change ships, and the privacy policy will be updated on the same day.
