What you get (+1 bonus)

What's live, market by market.
A snapshot, dated 7 October 2026, of ChatGPT ads in 31 European markets and the UK, bought self-serve, and of Google's AI Mode ads, not yet announced for any European market.
How ChatGPT ads work.
Who sees them, where they sit below the answer, and the four targeting levers, from context hints to custom audiences. In the EEA and Switzerland, ads are matched to the conversation, at least at first.
The consent trap.
The OpenAI Pixel assumes consent unless you tell it otherwise, so it can fire before a visitor says yes. The guide shows how to test yours in a fresh browser.
Shops and lead-gen, separately.
A chapter for shops, on product feeds and judging a test on orders, and one for lead-gen, on high-intent questions, where GA4 files AI visits and capturing each lead's source.
Five checks, then test or wait.
Five measurement checks to run before you spend, then a scored checklist of six must-haves for shops and six for lead-gen that says test now, fix first or wait.
+1 bonus
An AI skill for Claude, ChatGPT, Gemini or Copilot
that checks your measurement first, plans a country holdout or on/off test judged on orders that stuck or qualified leads, and reads out the result from your own exports.

Who it's for, and who it's not for

An online shop owner at a stockroom desk holds a phone with a chat app open, next to a printed order report and a laptop.

Who it's for

Owners and decision makers of online shops and lead-gen businesses in Europe or the UK deciding whether ChatGPT ads are worth a test this quarter.
Agencies and freelancers who run ads for clients and need a dated, sourced briefing on what's live, how it's bought and what can be measured.
Marketers who've been asked "should we test ChatGPT ads?" and want a scored answer based on whether their tracking could measure the result.

Who it's not for

Businesses that sell only outside Europe. The market details and dates in the guide are European, so much of it won't apply.
Advertisers already running ChatGPT ads with a measured holdout in place. You'll know most of what the guide covers.

Honest note

This is the Q4 2026 edition: facts checked on 7 October 2026, next review in January 2027. Both surfaces change fast, some details come from trade press rather than OpenAI or Google, and the guide marks those as reported. It can't predict whether ChatGPT ads will pay for your business, and its example figures are illustrative. A small test, measured against a holdout, is the way to find out.
