How to tell if ChatGPT is sending you customers

Owners ask us some version of the same question every week: “People keep saying they found us on ChatGPT. Is that real, and how much is it worth?” It’s usually real. It’s usually undercounted. And it’s answerable, if you look in three places instead of one.

Signal 1: ChatGPT visits in your analytics

This is the one everyone checks first, and the one that shows the least.

In Google Analytics 4, go to Reports → Acquisition → Traffic acquisition and look for the AI Assistant channel, added in May 2026. Switch the dimension to Session source and look for chatgpt.com. If you see visits there, ChatGPT is linking to you. Note which landing pages they arrive on: that’s what ChatGPT thinks you’re good for.

What this misses: visits from the ChatGPT phone apps often arrive without a referrer and show up as Direct. And it only counts people who clicked. (Full setup: AI traffic in GA4.)

Signal 2: what customers say

This is where most of the answer is, especially if customers call you.

The common path isn’t “click ChatGPT link, buy”. It’s “ask ChatGPT, get three names, Google one, read reviews, call”. That customer shows up in your analytics as Google, or not at all if they dialled the number from the answer. The only way to count them is to ask.

• Add “How did you first hear about us?” to your contact or quote form, with ChatGPT, Gemini and Other AI as options.
• Ask the same question on every phone enquiry and write the answer down.
• Keep track of how often it was asked, not just the answers. A low AI count from a question asked 20% of the time means nothing.

We wrote a whole post on this: the most valuable question you’re not asking.

Signal 3: what ChatGPT says about you

Open ChatGPT (logged out, or in a temporary chat) and ask what a customer would ask: “best [your service] in [your city]”, “[your service] near me for [a specific need]”. Try five or six variations. Note:

• Are you named? Where in the list?
• Who is named instead?
• Is what it says about you accurate: services, area, prices?
• Which websites does it cite?

If you’re named often, signals 1 and 2 should be showing something. If you’re never named, the handful of “found you on ChatGPT” comments may be people misremembering Google. That’s useful to know too.

The 15-minute check

1. GA4: note last month’s AI Assistant sessions and the top landing pages (5 min).
2. CRM or inbox: count how many of last month’s leads mentioned ChatGPT or AI anywhere (5 min).
3. ChatGPT: run five customer-style questions and note whether you’re named (5 min).

If two of the three show something, ChatGPT is sending you customers. The next question is how many, and what they’re worth.

Putting a number on it

Doing this by hand every month gets old, and it still doesn’t join the pieces: which visit became which lead, which lead became which job. That’s what Which AI Sent does. It follows AI visitors to the form, records customers who say they found you through AI, and counts the revenue when the job is won, with each lead labelled Confirmed or Declared so you know how solid it is. It also runs the ChatGPT check weekly.
