Early advertisers on OpenAI's ChatGPT ad platform say it gives them far fewer campaign controls than Meta or Google, along with weaker analytics. According to Marketing Brew, brands including ButcherBox, Vanta and Bark Technologies point to missing features such as search-volume targets and thin reporting, even as some report higher click-through rates and more traffic than expected. One point up front for readers here: ChatGPT ads are currently available only in the United States, so Thai advertisers cannot buy them yet.
What the early advertisers say is missing
The core complaint is control. On mature platforms, buyers can tune campaigns against a long list of signals and targets. On ChatGPT's ad product, that toolkit is much shorter. One specific gap the advertisers name is the absence of search-volume targets, which buyers use to size demand and plan spend against it.
Measurement is the second gap. OpenAI announced pixel-based measurement in May 2026, but robust reporting has not shipped yet. In its place, advertisers lean on UTM tracking and their own internal attribution to see how much top-of-funnel traffic ChatGPT sends. That is enough for a rough read on traffic, but it leaves the harder questions open.
The questions buyers still cannot answer
Two of them stand out in the reporting. The first is incrementality: whether the ads drive results that would not have happened anyway, rather than taking credit for clicks a brand would have won regardless. The second is scale: how far the channel can grow before returns flatten. Advertisers are actively asking OpenAI for measurement that answers both.
Real traction despite the gaps
The picture is not all negative. Some of these advertisers report higher click-through rates and more traffic than they anticipated, which is why they keep spending and keep pushing for better tooling. ChatGPT is cited at roughly 1 billion monthly users, so the potential audience behind the ad product is large. The tension is that early demand signals look promising while the controls and measurement that would justify bigger budgets are still immature.
This is the clearest read yet on where ChatGPT advertising sits against established platforms. There is genuine early traction, but the levers and reporting lag well behind what buyers expect from Meta and Google, and that gap is what will decide whether performance budgets start moving toward AI-chat inventory.
ChatGPT ads are US-only right now
To state it plainly: ChatGPT ads are available only in the United States at this stage, and Thai advertisers cannot run them. Nothing in the reporting points to a launch date for Thailand or the wider region. Treat this as a signal to watch rather than a channel to buy.
What this means for Thai marketers
Even without the ability to buy ChatGPT ads, the US experience is a useful preview. When a channel opens with strong reach but limited measurement, the brands that benefit first are the ones whose tracking foundations are already solid. Clean UTM conventions and dependable internal attribution are the same tools these early US advertisers are relying on, and they are worth having in place well before any regional rollout.
There is also an organic angle that is available today. ChatGPT already surfaces and cites content in its answers, so working on generative engine optimization and visibility inside ChatGPT is a way to show up in AI answers now, without waiting for the ad product to reach this market. The paid channel is a future option; the earned side of AI visibility is not blocked by geography.
Frequently asked questions
Can Thai businesses buy ChatGPT ads?
Not yet. Per Marketing Brew, ChatGPT ads are currently US-only, and there is no announced rollout date for other markets.
Why do advertisers say measurement is weak?
OpenAI announced pixel-based measurement in May 2026 but has not shipped robust reporting, so buyers rely on UTM tracking and internal attribution to gauge top-of-funnel traffic.
Are the ads working for early advertisers?
Some report higher click-through rates and more traffic than expected, though they are still asking for incrementality and scale measurement.
The measurement discipline that makes a new channel worth buying is the same discipline that improves the channels you run today. If you want to be ready to appear in AI answers and to measure any AI-driven traffic properly, our team can help you build that foundation now.
