ChatGPT Ads: What you should know before you get started

We’ve just come out of the opening weeks of a ChatGPT Ads campaign for a client, and I’ve got opinions. I’m Head of Paid Media at Liberty (hi!), and I’ve worked on a load of platforms, and every one of them have their own quirks.  But this one has felt genuinely different.

So rather than give you the polished press-release version, here’s the honest field report: what the platform actually is right now, what it’s good at, where it’s rough, and whether I’d put your budget anywhere near it (yet).

Why a brand-new ad channel matters this early

New ad platforms don’t come along often, and when they do, the brands that learn them early tend to buy attention cheaply before everyone else piles in.

And that’s the real prize here. OpenAI switched ads on inside ChatGPT for US free-tier users back in February 2026 and opened a self-serve Ads Manager to all US advertisers with no minimum spend, two months later, in May. In platform terms, that’s pretty fast.

People aren’t scrolling a feed or half-reading a search results page when they ask an AI a question. They’re mid-conversation, actively working through a decision, and your ad lands in that moment. We’ve covered this before, but the conversion rate is really high for organic traffic coming from an AI referral (See this webinar).

That’s a different kind of intent than anything Google or Meta offers, and it changes how we should think about the creative.

What’s actually different about buying ChatGPT Ads

If you came here expecting a Google Ads clone, you’ll trip over the differences fast – which is a good and a bad thing. Here’s what caught my attention:

There are no keywords to bid on

This was the biggest mental adjustment for me, personally. ChatGPT Ads are keywordless. You don’t build tight keyword lists or fight over exact-match terms. Instead, the platform reads the intent and context of a conversation and matches your ad to it. Very futuristic.

You can feed it “context hints” to steer things, but these are guidance signals, not the guaranteed keyword-level control we’re used to on search.

In practice, that shifts the work in a few ways:

• You have less say over which individual queries you show against, so precision targeting takes a back seat.
• Your creative message carries far more weight, because relevance is doing the job your keyword list used to do.
• Success rides on how well your offer maps to a real need in the conversation, not how cleverly you’ve structured a campaign.

For anyone who’s spent years living in search match types, this feels loose at first. Give it a week, and it starts to make sense: you’re buying relevance, not phrases.

Just one creative format

There’s a single ad format available at the time of writing. It’s made up of a headline, a short description, an image, and a landing page. That’s your lot. Enjoy!

I actually don’t mind the constraint, personally. When you strip away the format options, the only lever left is the quality of the idea – which is exactly what you want an ad to have. All the weak propositions have a lot fewer places to hide.

If you’re used to leaning on fancy ad types or endless variations to prop up a mediocre message, this platform will expose that quickly. Get your headline and offer sharp, point them at a landing page that delivers on the promise, and you’re most of the way there. This is where working with a team that treats PPC services as craft rather than button-pushing pays off.

Who actually gets to see your ad

Reach is deliberately narrow right now, and you need to plan around that. That’s purely because ChatGPT Ads aren’t available worldwide yet. The list of eligible countries is expanding in phases, so depending on where your business operates, you may not be able to run campaigns or reach users in every market you care about.

There’s a second layer too.

 At the time of writing, ads only show to eligible users on the Free and Go plans. Anyone on Plus, Pro, Business, Enterprise or Education won’t see them, and neither will under-18s. That has a real strategic implication: your audience skews toward users who haven’t paid to upgrade. Whether that matches your customer profile is a question worth answering honestly before you commit spend, because it won’t suit every brand.

Reporting is honest, but it’s still early days

The measurement side is where the platform’s youth shows most, but that’s fair. You get the core metrics you’d expect: impressions, clicks, CTR, CPM and CPC, spend, and conversions. UTM parameters work, so you can pull activity into your own analytics and see it alongside everything else.

What you don’t get yet is the advanced attribution and tracking that mature platforms have spent a decade building. So, temper expectations internally before launch.

You can absolutely see whether the campaign is working, but you can’t yet slice and model performance the way you might in Google Ads. Set the reporting expectations with your stakeholders early, and you’ll save yourself an awkward conversation later.

Not everyone can play yet

One thing that surprised a few people on our side: this isn’t fully open house. Brands still need approval to run ads on ChatGPT, including going through advertiser verification. Some sectors face tighter restrictions than others, with regulated markets like healthcare and financial services under closer scrutiny.

If you operate in one of those spaces, factor the approval process into your timelines rather than assuming you can launch next week. It’s not a barrier so much as a step, but it catches people out when they’ve already promised a go-live date to the board.

My final verdict

It’s early, the reach is limited, the reporting is basic, and not everyone can access it. Go in with those caveats understood, treat the first campaign as a genuine learning exercise, and you can build an edge while the channel is still young. ChatGPT Ads reward relevance and strong creative over budget muscle, which is exactly the kind of platform we like.

The mistake would be treating it like a mature platform and expecting mature results on day one. It isn’t one yet, and that’s precisely why it’s interesting.

If you’re weighing up whether advertising on ChatGPT is right for your brand, don’t go in blind. Talk to a team who knows paid media inside out, and we’ll tell you straight whether it’s worth your budget.
