ChatGPT starts selling ads on Monday. What matters still happens above the ad.
From Monday 24 August, ChatGPT shows ads in Denmark. It happens across 31 European markets at once — the whole EU plus Norway, Iceland, Liechtenstein and Switzerland — and it is the largest geographic expansion the platform has ever made in a single step. Ads appear for users on the Free and Go plans. Pay for Plus, Pro or Enterprise and you won't see them.
That's the headline everyone is running. The interesting detail sits one layer down, and it changes what is actually worth doing about it.
The ads are not personalised
At launch there is no profile behind the ad. OpenAI does not use past conversations, and does not use stored memories, to decide what you are shown. What picks the ad is:
- the topic of the conversation happening right now
- approximate location, device type, time of day and language
That is the entire targeting surface. Personalisation comes later, and only for users who actively opt in. Advertisers, for their part, receive aggregate numbers only — impressions and clicks. Not conversations, not names, not emails, not IP addresses.
For a European business that is an unusual starting position. There is no audience to build. No retargeting. No data head start for whoever has been hoarding behaviour for ten years. The only thing deciding whether your ad is relevant is the question the user just typed.
So the audience isn't a person. It's a question.
Which makes week one the cheapest time to learn
When nobody has a data advantage, the gap between a large advertiser and a small one is narrower than it will ever be again. That won't last — personalisation is already announced, and the day it lands, the usual advantages start working again.
Our recommendation is simple: don't wait to see what everyone else does. Not because the channel is proven — it isn't — but because the price of learning it will never be lower than right now. Access initially runs through OpenAI's own ads team, agency partners and technology partners; self-service through Ads Manager follows later.
But the ad sits below the answer
Here is the part worth stopping at, and the part we think matters more than the media buy itself.
Ads are clearly labelled and kept separate from ChatGPT's answers. Advertising does not influence what the model replies. That is a decent design — and it has a consequence most coverage skips straight past:
If ChatGPT answers a question in your field without mentioning you, you can now pay to sit underneath the answer that ignored you.
It is still worth doing. An ad in the right place is good business. But it is not the same as being the thing the model draws its answer from. That position cannot be bought. It can only be earned — by having content that genuinely answers the question, structured so a machine can read it, and possible to find.
Two different jobs. One costs money per click. The other costs work, and keeps paying after the campaign stops.
The good news is that both run on the same raw material
Look at what the two actually require.
The ad is targeted on the topic of the conversation. The answer is assembled from content that addresses that topic. Both hinge on the same question: what are your customers actually asking?
That isn't preparation for advertising. It IS the targeting — and it is the content plan at the same time. One piece of work, two payoffs:
- You know which conversations your ads belong in.
- You know what needs to exist for you to be the answer rather than the ad beside it.
Most companies can tell you what their customers google. Far fewer can tell you what their customers ask — and it's a different language. People google "reflexology Aalborg price". People ask "what does it usually cost, and how many sessions before it actually helps?"
The second question is the one being answered now. If you haven't written the answer, someone else has.
What we do about it
We build websites where this isn't a campaign you run once a year.
The site has agents built in that work continuously: content agents write and update, and SEO and GEO agents optimise for both classic search and for being picked up as a source in AI answers. It's the same engine that keeps the content alive and keeps it readable to the models that now also sell the ad space beside it.
And we encourage the other half. Test the ads. Start small, start next week, and use what you learn about the questions to decide what gets written.
We're happy to help with both — the foundation first, because that's the part that stays.
