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.
Beyond scoring, CrawlRanker identifies the content domain of your site — medical, legal, financial, e-commerce, and others — and cross-references it with your AI content score to surface governance risks. A medical site with high AI automation carries different liability exposure than a general blog. The free scan shows you the count; the Pro plan shows you exactly what the risks are, why they apply, and how to fix them.
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 doesn’t 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
The free single-URL scan — SEO audit, AI content score, and governance risk count — is free with no signup required, and it will stay that way. The infrastructure cost during the beta (Anthropic API calls, hosting, the database) is funded out of pocket.
Paid tiers are launching soon. Pro ($29/month) gives solo developers the full governance picture: a breakdown of every risk with severity, plain-English explanations, regulatory framework links, HTML fix snippets, and an AI-generated governance document. Business ($79/month) adds unlimited sites, white-label PDF reports, automated re-scanning with email alerts, team seats, and API access. See the pricing page for the full comparison, or join the waitlist to lock in the early-access rate.
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.
