What an AI visibility check actually measures
"AI visibility" is whether AI assistants can discover, trust, and cite your site when someone asks them a question. It comes down to signals most site owners never see: can AI crawlers read your pages (robots.txt, llms.txt, structured data), is your identity verifiable (DNS ownership, WHOIS, email authentication), and is the site technically trustworthy (SSL, security headers, DNSSEC, content trust)?
The free scan runs 43 checks across five categories — identity, technical security, content trust, reputation, and AI readiness — and rolls them into a single trust grade (A+ through C). Paid tiers add a persistent, embeddable trust badge, continuous monitoring, and the GEO Citation Checker, which asks Claude with live web search whether your domain actually gets cited.
A free alternative to Profound, Otterly & Peec AI
Dedicated AI-visibility platforms like Profound, Otterly.ai, and Peec AI are powerful — they continuously track your brand's share of voice across many AI engines, and they're built for marketing teams with budgets that start around $20/mo and climb past $495/mo. If you need ongoing, multi-engine monitoring and attribution, they're the right tool.
But if you just want to answer "is my site even AI-ready, and would an AI trust it enough to cite?" — you shouldn't have to start a paid subscription to find out. AI-Signed gives you that check for free, instantly, and adds a verifiable trust badge and basic citation check from $5.99/mo. Here's the honest breakdown:
| Capability | Paid GEO suites (Profound, Otterly, Peec) | AI-Signed |
|---|---|---|
| Free, instant AI-readiness scan (no signup) | Partial | |
| 43-point trust, security & identity audit | ||
| Embeddable, machine-readable trust badge | ||
| Checks if AI can find & parse your site (llms.txt, structured data) | Partial | |
| Continuous multi-engine share-of-voice monitoring | Partial | |
| Competitor citation benchmarking across many LLMs | Partial | |
| Starting price | $20–495/mo | Free · $5.99/mo |
"Partial" reflects honest scope: the paid suites offer limited or trial-only free scans, and AI-Signed's monitoring covers Claude today (Perplexity, Gemini, and Google AI Overviews are on the roadmap). Product names are trademarks of their respective owners; comparison is for reference only.
Frequently asked
How do I check if ChatGPT or Perplexity cites my site?
Start with the free scan above — it tells you whether your site is technically AI-ready (crawlable, structured, trustworthy), which is the prerequisite for being cited at all. To see whether AI actually cites you today, the GEO Citation Checker (from $5.99/mo) runs natural-language prompts against Claude with live web search and reports whether your domain is cited, whether your brand is mentioned, and which competitors get cited most.
Is the AI visibility checker really free?
Yes. The 43-check scan and your letter grade are free with no signup and no card. You only pay if you want the persistent embeddable trust badge, continuous monitoring, or the GEO Citation Checker — starting at $5.99/mo.
What makes a site "AI-ready"?
An AI-ready site is one that AI crawlers can access and parse (clean robots.txt, llms.txt, structured data, a sitemap), whose identity is verifiable (DNS ownership, WHOIS, email authentication), and that is technically sound (valid SSL, security headers, DNSSEC) with real content trust signals (privacy policy, terms, contact info). AI-Signed checks all of these and grades them.
How is this different from Profound or Otterly?
Those are paid, continuous AI-visibility monitoring platforms for marketing teams ($20–495/mo). AI-Signed is a free instant readiness and trust check plus an optional low-cost badge — the fastest, cheapest way to find out whether your site qualifies to be cited, without committing to a subscription.
