Most websites are invisible to AI. We find out why.
ChatGPT, Perplexity, and Claude now answer the questions your customers used to Google.
WHAT WE CHECK
AI Visibility
Checks whether GPTBot, ClaudeBot, PerplexityBot, and other AI crawlers can access your site. Detects missing llms.txt, blocked crawlers, and cloaked pre-rendering that hides content from machines.
SEO Health
22+ automated checks across robots.txt, sitemaps, structured data, canonicals, security headers, Core Web Vitals, and more. Finds the crawl budget killers and ranking leaks other tools miss.
Citation Testing
Live queries against Perplexity and Claude to see if your site gets cited when buyers ask relevant questions. Based on University of St. Gallen research on AI citation stability — we run every test twice.
Weekly Monitoring
Your visibility changes every day as AI models update. We re-audit weekly, track your scores over time, and email you a monthly digest of what improved, what regressed, and what to fix next.
PRICING
One scan. Two scores. Real answers.
Paste your URL. In about 30 seconds, Fetchling runs deterministic checks across your robots.txt, sitemap, structured data, canonical tags, security headers, and AI crawler access, then shows SEO and AI-readiness scores plus the findings it can safely determine. No email is required to view or download the free results. The full report adds multi-page crawling, real Core Web Vitals, live citation tests against Perplexity and Claude, and a priority-ranked action plan with exact fixes.
Never lose ground again.
AI models update. Crawler rules tighten. Your scores drift. A one-time report tells you where you stand today — but next week ChatGPT changes, Perplexity re-ranks, and ClaudeBot shifts its crawl policy. Membership re-audits your site every seven days, charts your scores over time so you see trends before they become problems, and sends one monthly digest of what improved, what regressed, and what to fix next. Cancel anytime.
QUESTIONS
What does the free scan check?
It fetches your site the way a crawler does and reports what it finds: robots.txt and sitemap.xml, whether GPTBot, ClaudeBot, PerplexityBot and Googlebot are allowed through, canonical tags, structured data, indexing signals, outbound links, and baseline security headers. It takes about 30 seconds.
Do I need an account to run a scan?
No. Paste a URL and the scan runs. Results are available immediately, and you can optionally email yourself the free report after it finishes.
How is this different from a normal SEO audit?
A standard SEO audit focuses on conventional search signals. The free Fetchling scan checks whether AI and search crawlers can reach and read the homepage; the paid report separately measures live citations. A site can pass traditional SEO checks while still blocking an AI crawler or hiding its content behind JavaScript.
Can you actually tell whether ChatGPT or Perplexity cites my site?
Yes, in the paid report. We ask Perplexity and Claude real buyer-intent questions for your market, record every source they cite, and report how often your domain appeared. It is a live measurement rather than an estimate.
What is in the $19 report?
Your homepage plus up to seven more pages, live citation testing against Perplexity and Claude, real Core Web Vitals measured through Google PageSpeed Insights, and structured-data checks that look at field completeness rather than only presence. Every finding comes with the evidence behind it, why it matters, and the exact fix.
What does the $29 per month membership add?
It re-audits one site every week and keeps every scan, so you can see your scores move over time. Once a month you get a digest of what improved, what regressed, and what to fix next. If nothing meaningful changed, it says so. Cancel anytime.
"Fetchling is built and run by one person, not a team. I originally built it as an internal tool for my local marketing agency to catch a gap in client sites: ranking fine on Google while staying invisible to ChatGPT and Perplexity. Enough other site owners had the same blind spot that I turned it into its own product."
