What is AI referral traffic?
AI referral traffic is the visits that reach your website when people follow links in AI assistants' answers. It is measured in your analytics and server logs, separately from crawler requests.
What AI referral traffic means
When someone clicks a link on one site and lands on yours, their browser usually sends a referrer. That is the address of the page they came from. Analytics tools and server logs use it to say where a visit came from.
AI referral traffic is the share of visits whose referrer points to an AI assistant. A person read an answer, saw a link to your site and chose to follow it.
How Google Analytics groups AI visits
Google Analytics sorts visits into default channels. One of them is called AI Assistant. Google describes it as visits from sources such as ChatGPT, Gemini, Deepseek, Copilot or Grok.
Analytics puts a visit in this channel when its referrer matches Google's list of AI assistants. A visit tagged with the medium ai-assistant is grouped there too.
Google's own AI experiences are treated differently. The AI Assistant channel excludes AI Overviews. Clicks from those count as Organic Search, alongside ordinary search results.
Why some AI visits go uncounted
Not every request carries a referrer. The HTTP standard, RFC 9110, notes that not all requests contain one. It also says a browser may trim the referrer down to just the site's address.
A visit with no referrer can land in a direct or unassigned bucket. Google Analytics defines Direct as arriving through a saved link or by typing the address.
Campaign tags on a link can also label a visit. Anyone can add a tag, though, so treat a tag alone as probable rather than confirmed. Any count of AI referrals is therefore a floor.
How Carqo relates to AI referral traffic
Measurement in Carqo is built to count the visits that reached your website from AI assistants. It uses the logs you upload. Connecting Search Console is coming soon.
Every metric has its meaning written beside it. Visits with no referrer are counted as arrivals that could not be traced, so the attributed figure isn't read as the whole. A source that isn't connected reads Not connected, never zero.
In practice
- Open the AI Assistant channel In Google Analytics, look at the AI Assistant channel for a set date range.
- Break it down by source See which assistants sent visits. Keep the date range the same when you compare periods.
- Check the landing pages Note which pages those visitors arrived on. Check the facts on those pages first.
Common questions
Is AI referral traffic the same as AI crawler traffic?
No. Crawler traffic is software fetching pages for an AI company. Referral traffic is people clicking a link in an AI answer. Measure them separately. A crawler request has no reader behind it at all.
Why is my AI referral count lower than I expected?
Some visits arrive with no referrer and are recorded as direct. Others may be tagged in ways your tools do not recognise. Treat the count as a floor. Reading your server logs beside your analytics gives a fuller picture.
Does more AI referral traffic mean more sales?
Not by itself. A visit is not an enquiry, and an enquiry is not a sale. Measure each step with its own source.
