- The llemmy Tag is one line of script that measures the humans who arrive on your site from AI answers, and ties them to revenue.
- It’s cookieless by default, never stores raw IPs, and never blocks your page.
- One install unlocks four things: measure AI traffic, prove revenue, personalize for AI visitors, and pipe conversions to your stack.
- AI crawlers don’t run JavaScript, so the tag is about human AI-referral traffic, not bots.
Why a tag at all?
GEO tools can tell you that an AI answer mentioned you. They can’t tell you whether anyone actually came, or bought. That’s the gap the llemmy Tag closes. llemmy already knows which AI answers cite which URLs; the tag captures the visitor who arrived on that URL and what they did. Owning both halves (the citation and the on-site outcome) is the only way to say “AI search drove $X this month, and here’s the answer that did it.”
What one line unlocks
1. Measure AI traffic
See which AI engines (ChatGPT, Perplexity, Gemini, Claude, Copilot, Grok) actually send visitors to your site, how much of your traffic now starts in an AI answer, and which pages they land on. (Google AI Overviews is deliberately not counted as AI: its referrer is indistinguishable from an ordinary Google visit, so counting it would overstate the number.)
2. Prove revenue
Fire a conversion when a visitor signs up or buys, and llemmy attributes that revenue to the AI engine (and the exact tracked answer) that referred them. You get revenue, conversion rate and average order value by engine, plus a ranking of your top-earning pages.
3. Personalize for AI visitors
The tag marks each page with how the visitor arrived, so you can show tailored content (“Came from ChatGPT? Here’s the 60-second version”) to the traffic that matters most.
4. Integrate
Every AI-referred conversion can fire a webhook, so you can push AI-driven revenue straight into HubSpot, Salesforce, Slack or Zapier and act on it in real time.
Install it (30 seconds)
In llemmy, open AI Traffic → Setup, create a site, and copy your one-line snippet. Paste it into the <head> of every page.
<script async src="https://llemmy.com/t.js" data-llemmy="YOUR_SITE_KEY"></script>
It loads asynchronously and sets no cookies. Once your first visitor lands, the Setup tab’s health dot turns green (“Receiving data”).
Track conversions (unlocks revenue)
Call llemmy('track', …) wherever a visitor converts (a signup, a purchase, a booking) and pass a value to attribute revenue:
llemmy('track', 'signup', { value: 49, currency: 'USD' })
That’s it: no extra script. The conversion is stitched to the visitor’s session and credited to the AI engine and answer that drove it. Revenue figures are reported in your dominant currency.
Personalize for AI visitors
Add data-llemmy-when="ai" to any element to show it only to visitors who arrived from an AI engine (or "not-ai" for everyone else). For custom logic, window.llemmy.ai.engine holds the engine name, or is null for non-AI visits.
Pipe AI conversions to your stack
Subscribe a webhook to the tag.conversion event and llemmy will POST every AI-referred conversion to your endpoint, with engine, value, currency and landing page included (and never any raw IP or visitor identifier). Use it to route AI-driven leads in your CRM, alert your team in Slack, or trigger a Zap.
Privacy by design
The tag is cookieless by default and llemmy never stores raw IP addresses. Sessions use an ephemeral first-party identifier; in consent mode, tracking identifiers are dropped when a visitor declines. Privacy isn’t a trade-off here: it’s the default.
How is this different from Google Analytics?
GA can show a trickle of “chatgpt.com / referral” sessions, but it doesn’t classify the full set of AI engines, doesn’t tie a visit back to the specific AI answer that caused it, and doesn’t connect to your AI-visibility data. The llemmy Tag is purpose-built for the AI-search era and closes the answer to visit to revenue loop.
Will it slow down my site?
No. The script is tiny, loads asynchronously, and never blocks rendering. It fails silently if anything goes wrong, so it can never break your page.
