Can Google Analytics or Plausible track AI agents?
Partly. Web analytics can show visits with an assistant referrer if you build and maintain the segment yourself. It cannot see crawlers, which never run its script; it cannot see MCP or WebMCP tool calls, which never leave the browser; and it cannot tell an agent's conversion from a person's. Agent Tracking covers those three and runs beside your analytics rather than replacing it.

What web analytics sees
A referral from chatgpt.com or perplexity.ai is a normal page view with a referrer, and GA4, Plausible and Matomo record it. Whether they name the assistant depends on you: GA4 needs a custom channel group, Plausible a filter on referrer, Matomo a segment. Each of them has to be updated when an assistant changes its domain.
What it cannot see
GPTBot, ClaudeBot and PerplexityBot fetch HTML and never execute JavaScript, so no analytics script fires; only the server log knows they were there. A WebMCP tool call happens inside the visitor's browser between the assistant and the page; no request reaches any analytics endpoint. And a purchase completed by an agent looks exactly like a purchase completed by a person, so nothing separates the two.
What Agent Tracking adds
Crawler fetches from the server log, verified against the vendors' published IP ranges and grouped into bursts. Tool calls with duration, success rate, error class and input key names. Conversions attributed to agents through a goal marker. And assistant referrals from a maintained list, so nobody has to build the segment.
Use both
Keep your analytics for people. Add one script tag for agents. The two do not overlap, and the agent dashboard stays small enough to read in a minute.
<script defer data-domain="example.com" src="https://agenttracking.co/agent.js"></script>
In short
Does Agent Tracking replace my analytics?
No. It counts a different population. Human traffic appears only as a daily total for context.
Can I build all of this in GA4 with enough work?
The referral part, yes. The crawler part needs log processing outside GA4, and tool calls and agent conversions need code in the page that GA4 does not provide.
