AI visibility tracking
ChatGPT, Perplexity, Gemini, and Copilot are sending referral traffic — but standard analytics misses it. WebmasterID Agent detects AI referral patterns and surfaces which content is being cited, ignored, or at risk.

What the AI layer surfaces
Referral pattern detection
WebmasterID Core identifies traffic originating from AI surfaces using referrer headers and UTM pattern matching against a maintained registry of known AI referral domains.
Citation velocity
Track how often each AI source is sending traffic to your site over time. Spikes in AI referrals surface immediately as signals in the Agent Brain.
Page-level AI traffic breakdown
See which specific pages are being cited by AI sources. Identify your highest-performing AI-cited content and replicate its patterns.
AI vs organic comparison
Compare AI referral traffic against traditional organic search traffic. Understand the share of AI-sourced sessions and how it trends over time.
Work package generation
When the Agent detects that a page is gaining AI visibility but lacks structured data or authoritative signals, it queues a work package to reinforce those pages.
Zero-click risk surfacing
Pages losing organic clicks while AI referrals hold steady may be experiencing zero-click cannibalisation. The Agent flags these for content strategy review.
Frequently asked questions
How does the Agent detect AI referrals without JavaScript on the AI surface?
AI surfaces like ChatGPT and Perplexity send recognisable referrer headers when linking out to cited sources. WebmasterID Core pattern-matches these headers against a maintained registry of known AI referral domains and UTM patterns injected by some AI surfaces.
Is this the same as tracking llms.txt?
No. llms.txt is a specification for communicating your content structure to LLMs. AI visibility tracking measures actual referral traffic arriving at your site from AI surfaces — it is about observed behaviour, not intent signalling.
What if an AI surface does not send a referrer header?
Some AI surfaces suppress referrer headers in certain contexts. The Agent uses a combination of referrer matching, known UTM patterns, and session fingerprinting to maximise detection coverage, but some dark traffic from AI sources may remain unattributed.
Does this work without GA4?
Yes. AI referral detection is powered by WebmasterID Core analytics — GA4 is an optional enrichment provider. You do not need GA4 to start tracking AI visibility.
