Can AI engines even read your site?
ChatGPT can only cite what its crawler is allowed to read. AuditJet audits the nine technical signals that decide whether AI engines can find, access, and understand your pages — then monitors them so a stray robots.txt rule never makes you invisible.
Being citable starts with being readable
Everyone is talking about getting cited in AI answers. But before an engine can cite you, its crawler has to be allowed in, reach your pages, and parse them into something it understands. That technical layer is where most sites quietly fail.
A single Disallow: / aimed at GPTBot, an invalid JSON-LD block that silently doesn't parse, or a theme update that strips your structured data can make you invisible to AI search — with no ranking drop to warn you.
AuditJet audits that layer directly: it fetches your homepage, robots.txt, sitemap, and llms.txt, checks nine AI-readiness signals, and scores them 0–100 with a prioritised, copy-ready fix for every failure.
Then it keeps watching. Because AI readiness isn't a one-time fix — it regresses with every redeploy, plugin update, and robots.txt edit — AuditJet re-audits on a schedule and alerts you the moment a signal breaks.
What the AI Visibility audit checks
Detects whether GPTBot (ChatGPT), PerplexityBot, ClaudeBot, Google-Extended, and other AI crawlers are blocked in your robots.txt — the single most common reason a site is invisible to AI search.
Validates the signals AI engines use to understand and cite a page: JSON-LD structured data (and whether it actually parses), Open Graph tags, title, meta description, canonical, and an XML sitemap.
Every signal is scored and ranked by impact, with a concrete, copy-ready fix for each failure — the exact robots.txt line, JSON-LD block, or llms.txt template to add.
Re-audits on a schedule and flags the moment a change — a new Disallow rule, a theme update that drops structured data — breaks a signal, so you fix it before it costs you citations.
AuditJet audits your site's technical AI readiness. It does not send prompts to AI engines or count brand mentions in their answers — it makes sure those engines can reach and understand your content in the first place.
How to improve your AI readiness
Check that GPTBot, PerplexityBot, ClaudeBot, and Google-Extended aren't disallowed — and that no global Disallow: / is locking every crawler out. This is the highest-impact fix and the one most sites get wrong without realising it.
This emerging standard tells AI crawlers which pages to index and prioritize. Include your most authoritative, factually accurate content. AuditJet's free generator creates one from your sitemap.
Schema.org JSON-LD (Organization, Article, FAQPage, HowTo) gives AI engines machine-readable signals about your content — but only if the JSON actually parses. Invalid JSON-LD is silently ignored, which the audit flags explicitly.
og:title, og:description, og:image, a strong title tag and meta description are the snippet-level signals AI interfaces use to represent your pages. Missing or truncated values weaken how — and whether — you're surfaced.
Once the technical layer is clean, content earns citations. Long-form guides, original research, and well-structured how-to content demonstrate the expertise and factual accuracy AI systems prefer to cite.
FAQ
What is an AI visibility audit?
It checks whether AI engines can technically discover, access, and understand your site — the prerequisites for ever being cited in an AI answer. AuditJet scores nine signals: whether GPTBot, PerplexityBot, ClaudeBot and other AI crawlers are allowed in robots.txt, whether an llms.txt file is present and valid, whether your pages have valid structured data (JSON-LD), Open Graph tags, meta descriptions, title tags, a canonical, and an XML sitemap. The result is a 0–100 AI Readiness score with a prioritised fix list.
Does AuditJet query ChatGPT or Perplexity to see if my brand is mentioned?
No — and we won't claim to. AuditJet audits the technical readiness layer: it fetches your homepage, robots.txt, sitemap, and llms.txt and checks whether AI crawlers can reach and parse your content. It does not send prompts to ChatGPT or Perplexity or count brand mentions in their answers. It answers the question that comes first: 'can these engines even read and cite my site?' — because if a crawler is blocked or your markup is unparseable, no amount of content strategy will get you cited.
Why does AI readiness matter?
AI-generated answers increasingly sit at the top of search, and they draw on content their crawlers were allowed to read and could parse. A single misconfigured Disallow rule can lock GPTBot or PerplexityBot out of your entire site — silently. Many sites unknowingly block AI crawlers, ship invalid JSON-LD, or have no llms.txt at all. This audit surfaces those blockers before they cost you citations.
What is an llms.txt file and do I need one?
llms.txt is an emerging standard (similar to robots.txt) that tells AI crawlers which pages they're permitted to read and how to cite you. Adding one helps ensure AI systems index your most authoritative content. AuditJet checks whether yours exists and is valid, and its free llms.txt generator can create one from your sitemap.
Does AuditJet monitor AI readiness continuously?
Yes. Once you add a site, AuditJet re-runs the AI readiness audit on a schedule so a change — a new robots.txt rule, a theme update that drops your structured data, a redeploy that breaks canonical tags — is caught and flagged, rather than silently making you invisible to AI engines until you happen to notice a traffic decline.
How is Generative Engine Optimization (GEO) different from SEO?
Traditional SEO optimizes pages to rank in search results. GEO optimizes content to be discoverable and citable by AI-generated answers. AI readiness — crawler access, structured data, clear entity signals — is the technical foundation of GEO, and it's exactly what this audit measures and monitors.
