SEO audit API: Page-by-page SEO and AI search checks with ranked fixes and a report.

This SEO audit API crawls a website and returns, for every page, a one-line verdict, six 0 to 100 scores and the exact issues with how to fix them: indexability, titles and descriptions, headings, structured data, hreflang, broken links, redirects, and whether AI crawlers such as GPTBot, ClaudeBot and PerplexityBot are allowed to read the page. Each run also writes a standalone HTML report you can send to a client.

SEO audit API: questions

Does it run JavaScript like a browser?

No, on purpose. It reads the HTML that search engines and AI crawlers receive first, and flags pages whose main text only appears after scripts run, because many AI crawlers read pages without running scripts.

Does it check Core Web Vitals?

No. It covers technical and on-page SEO, structured data and AI crawler access. Use Lighthouse or PageSpeed Insights alongside it for speed.

Will it crawl my whole site?

Up to the page limit you set, from 1 to 10,000 pages per site, at no more than two requests a second, and it obeys robots.txt. A thousand pages take about nine minutes.

Does the score predict rankings?

No. The scores are a transparent checklist with the formula shown, not a prediction of Google rankings or AI citations.
