LLM Referral Tracking

Track visitors who found you through ChatGPT, Claude, and Perplexity.

Last updated Feb 3, 2025

What Is LLM Referral Tracking?

When someone uses ChatGPT, Claude, or Perplexity and the AI recommends your business, that person might click through to your website. LLM Referral Tracking identifies these visitors — the humans who found you via AI assistants.

This is different from bot tracking (which tracks AI crawlers). Referral tracking captures actual potential customers.

How It Works

  1. A user asks an AI assistant a question
  2. The AI mentions your business or provides a link
  3. The user clicks through to your site
  4. CitedPro detects the AI platform as the referrer
  5. The visit is logged with the source platform identified

Tracked Platforms

CitedPro detects referrals from 18+ AI platforms:

Viewing Referral Data

  1. Go to CitedPro → Analytics
  2. Look for the LLM Referrals section

  • Timestamp: When the visit occurred
  • Trend data: Referrals over time

Why This Matters

Measure AI Search ROI

For the first time, you can quantify how much traffic AI assistants send to your site. This helps justify investment in AI search optimization.

Understand User Intent

Users arriving from AI assistants often have high intent — they've already gotten an AI recommendation and are now researching further.

Track Platform Trends

See which AI platforms mention you most. This reveals where your visibility is strongest and where there's opportunity.

Technical Details

Detection Method

CitedPro uses JavaScript to check the document.referrer when a page loads. If the referrer matches a known AI platform domain, it's logged as an LLM referral.

Privacy Considerations

  • Only the referrer domain is stored (not the full URL)
  • No personally identifiable information is collected
  • Data is stored locally in your WordPress database

Limitations

  • Direct links (no referrer) can't be attributed
  • Some browsers strip referrer headers for privacy
  • Mobile app referrals may not pass referrer data
