Somebody types your business into ChatGPT, sees your name, takes a screenshot, and declares victory. Next day they ask again and you're gone. Champagne returned to the fridge.


That screenshot proves nothing. It's a selfie with a chatbot.

Here's what to measure instead.

Quick words (one line each):

  • Prompt: the question someone types into an AI tool.

  • Referral traffic: visits that arrive by clicking a link on another site (like chatgpt.com).

  • GA4: Google Analytics 4, Google's free visitor-tracking tool.

  • Dark traffic: visits that came because of AI, but analytics can't tell.

  • Search Console: Google's free tool that shows how your site does in Google search.

Why hand-checking prompts is a waste of time

Exposure Ninja studied 59 UK prompts and about 8,000 AI answers. ChatGPT cited the same websites two days in a row only 2% of the time. Google AI Overviews: 6% (1:00, Oct 19, 2026).

And the tools don't agree with each other either. ChatGPT and AI Overviews shared zero websites 49% of the time (1:30).

So one prompt, on one tool, on one day, is a coin flip with extra steps. Exposure Ninja's advice: stop showing single prompt screenshots as proof.

Step 1: Make AI visits and money your main number

Charlie Whitworth (on Candour's podcast) says use AI referral traffic and the revenue it brings as your main number, not citation counts or "visibility scores" (22:32-24:00, Oct 4, 2026).

In GA4, look at your referral sources and pull out the AI tools (sources like chatgpt.com and perplexity.ai). Track visits, leads and sales from them every month.

Step 2: Know that GA4 sees only a slice

Exposure Ninja says GA4's "AI assistant" traffic is a small slice, and a lot of AI traffic is dark (15:01-16:31). He quotes Similarweb data: after an AI recommends a brand,

  1. 56% go and search the brand name,

  2. 20% go straight to the website,

  3. 8.8% click through from the AI tool.

He also says clicks from Google AI Overviews are counted as normal organic traffic. So your AI number in GA4 is the floor, not the ceiling.

Step 3: Ask every lead one question (yes, just ask)

This is the cheapest, most honest tracking tool on earth: "How did you hear about us?"

Exposure Ninja says ask every new lead. At one client, ChatGPT was the top answer people gave, but only about #7 in analytics (20:31 and 21:31-22:01). His words: "Don't wait for perfect attribution."

Peec AI goes one step further: ask new signups which exact prompt they typed (25:00-26:32, Sept 30, 2026).

Add it to your contact form with options like:

  • ChatGPT

  • Google AI answer

  • Google search

  • Friend or referral

  • Other (with a text box: "What did you ask?")

Step 4: Open the AI report in Search Console

Exposure Ninja says Search Console has a generative AI performance report (he says it launched 3 June 2026). It shows impressions only, no clicks (19:01-20:02). Google's own Search news video (Oct 26, 2026) says the generative AI features report is now rolled out to all sites, for Search and Discover. Either way, it's there now, so go look.

Impressions means "you were shown." Useful for trends. Not a trophy. Don't sell it to your boss as revenue.

Peec adds a cleanup tip: filter queries from prompt-tracking tools out of your Search Console data so automated checks from tracking tools don't get mixed in with real searches (8:00-9:01).

Step 5: Set up Bing Webmaster Tools

Charlie Whitworth says set up Bing Webmaster Tools and look at its AI insights (16:00). Surfer Academy says Bing has AI citation reporting (0:00-1:30, Sept 30, 2026). It's free. Do it.

Step 6: If you track prompts, track the right ones

If you use a prompt-tracking tool, Exposure Ninja says:

  1. Check the right country and location before comparing with competitors (4:01).

  2. Only chase prompts that make money. Filter by buying intent and decision stage (6:30-7:30).

  3. Check each AI on its own, since they pick different sites (1:30).

Peec adds: check both directions. "[Brand] ? trait" (what does AI say about you?) and "trait ? [brand]" (does AI name you when someone asks for that trait?) are not the same thing (28:00-29:00).

The monthly report, in one box

  • AI referral visits and leads - Where: GA4; Why: Real people, real money

  • "How did you hear about us?" answers - Where: Contact form; Why: Catches the dark traffic

  • AI impressions - Where: Search Console; Why: Trend of being shown

  • AI insights - Where: Bing Webmaster Tools; Why: Copilot side of the picture

Heads-up

Exposure Ninja (sponsored by Ahrefs), Peec AI (sells a tracker) and Candour (agency) all sell something. Their numbers are their own data. The advice to measure real visits and ask real people costs nothing and works on any site.

Do this today

  1. Add "How did you hear about us?" with a ChatGPT option to your contact form.

  2. In GA4, find your AI referral sources and write down last month's visits and leads.

  3. Open the generative AI report in Search Console.

  4. Set up Bing Webmaster Tools if you haven't.

  5. Delete the screenshot folder. You know the one.
