Is FreePageRank actually free?
Yes. 100% free, no credit card, no signup required. Paste a URL, get a full audit. That's it.
What data sources do you use?
We use the Google PageSpeed Insights API for performance and Core Web Vitals, a custom crawler for SEO and accessibility signals, DNS/WHOIS lookups for domain data, and our proprietary AI engine for the crawler simulation and content analysis.
How is the AI Crawler Audit different from a regular SEO audit?
A standard SEO audit checks if Googlebot can crawl you. Our AI Crawler Audit simulates GPTBot (ChatGPT), ClaudeBot, and Perplexity — the AI crawlers that power AI search answers. It shows you whether you're blocked, what content they extract, and how to improve your AI citation potential.
How long does an audit take?
Under 3 seconds for most sites. Complex sites with many redirects may take up to 5–6 seconds.
Can I use this for client reports?
Absolutely. The report is designed to be professional and shareable. Many SEO agencies use FreePageRank for initial client onboarding audits.
Is there an API?
API access is on the roadmap. Follow the project or star this repo to be notified when it launches.
