Is your site visible to AI search?
Free AI search visibility checker. Test whether ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews can read and cite your site — instantly. No signup.
We test the engines your customers actually use.
Each AI engine uses a different crawler and rewards different signals. We check all six, then return one score per engine plus the fastest fixes to climb each.
What we check on every scan
AI bot access
If GPTBot, ClaudeBot or PerplexityBot can’t crawl your site, you’re invisible to that engine — full stop. We check robots.txt, server headers, and Cloudflare bot policies for every major AI crawler.
- robots.txt access for 8 major AI user agents
- Cloudflare AI Audit / Bot Fight Mode detection
- Server response codes per AI bot
- `llms.txt` + `llms-full.txt` presence
Citable content blocks
LLMs lift sentences and paragraphs, not pages. Your content needs to be quotable in 1–3 sentence chunks with clean attribution paths and direct answers near the top.
- Direct-answer paragraph detection (40–80 words)
- Question-format headings (matches real queries)
- Definition + example + caveat triad
- Listicles and tables (top-cited by LLMs)
Schema for AI Overviews
Google AI Overviews and Perplexity cite FAQPage, HowTo, Article and Product schema disproportionately. We validate every JSON-LD block against rich-result eligibility.
- FAQPage · HowTo · Article · Product schema validation
- Speakable + BreadcrumbList markup
- Author + datePublished + dateModified presence
- Organization sameAs entity disambiguation
Trust & freshness
AI models weight author credentials, citation density, freshness stamps and entity strength. We score every signal the major engines flag for trustworthy answers.
- Named author with bio + credentials
- Outbound citations to .gov/.edu/journals
- Freshness stamps (datePublished + dateModified)
- Wikipedia / Wikidata entity links

AI search visibility, explained.
What is AI search visibility?+
AI search visibility measures whether your website can be read, indexed and cited by AI-powered search engines and assistants — ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude, and Microsoft Copilot. It depends on three things: whether their crawlers can access your site, whether your content is structured in quotable chunks, and whether your schema and trust signals let the model confidently attribute the answer back to you.
How is this different from a regular SEO audit?+
A regular SEO audit checks if Google can rank your page in ten blue links. An AI visibility check adds four more layers: (1) AI bot access — GPTBot, ClaudeBot, PerplexityBot, Google-Extended must be allowed; (2) citable content structure — 40–80 word self-contained paragraphs; (3) AI-friendly schema — FAQ, HowTo, Article, Speakable; (4) verifiable EEAT — named authors, outbound citations, freshness stamps.
Why might ChatGPT or Perplexity not cite my site?+
The five most common reasons we see in scans: (1) robots.txt blocks GPTBot or PerplexityBot, (2) Cloudflare AI Audit is set to block AI bots by default, (3) content is rendered client-side via JS that LLM crawlers don’t execute, (4) no FAQ/Article/HowTo schema exists for AI Overviews to lift from, (5) content lacks direct-answer paragraphs near the top of the page.
How does SlapMyWeb’s AI visibility checker work?+
You paste a URL — no signup required — and we run 240 checks across 16 specialist modules in parallel. The AI Visibility module specifically checks crawler access, citable content structure, AI-friendly schema, and trust signals. You get a 0–100 score per engine (ChatGPT / Perplexity / Gemini / AI Overviews), prioritized fixes, and copy-paste code snippets.
Is the checker really free?+
Yes — the full check, score and fix recommendations are free with no signup. Paid plans (Pro / Agency / Enterprise) add unlimited scans, white-label PDF reports, citation tracking across ChatGPT/Perplexity/Gemini over time, and multi-client dashboards.
What’s the difference between AEO and AI search visibility?+
AEO (Answer Engine Optimization) is the practice — the work you do to make your site cite-worthy. AI search visibility is the outcome — whether AI engines actually find, parse and cite you. The SlapMyWeb AI Search Visibility Checker measures the outcome; our /answer-engine-optimization page covers the practice.
