What is AI referral traffic?

By the Variask team · Updated

Definition

AI referral traffic is the visits your website gets from people clicking links in AI assistants such as ChatGPT, Perplexity, Gemini, Claude and Copilot.

Also called LLM traffic, AI traffic

With Variask: Variask shows visits from ChatGPT, Perplexity, Gemini, Claude and Copilot next to your organic search traffic, plus AI crawler visits.

How to track it

  • Analytics tools show many AI visits by referrer, such as chatgpt.com or perplexity.ai.
  • Some AI visits arrive without a referrer and look like direct traffic, so totals are usually undercounted.
  • Tagging links where you can, and looking at landing pages, helps fill the gaps.

What the numbers tell you

AI visitors often arrive further along in their decision, because the assistant already explained the options. Watch conversions and engagement, not only volume.

What it means for brands

  • Report AI traffic next to organic search so leadership sees the trend.
  • Look at which pages AI sends people to; those are your best AI entry points.
