How many people can a ChatGPT ad actually reach?
Describe the audience you want, in your own words. You get the size of the opportunity, what a click should cost on ChatGPT Ads, and the budget a real test needs, with the arithmetic shown for every figure.
[ The estimate ]
The same kind of description you would give ChatGPT Ads: the conversations, topics or moments where what you sell is relevant. Not keywords.
Takes about ten seconds. We email you the estimate when it is done.
[ How the numbers are built ]
We read your hint the way the ad platform does
ChatGPT Ads match on described context, not exact keywords. We take your description and work out the searches the same person would type, because searches are the only public record of that demand.
We price those searches against live data
Every phrase is checked against a live Google keyword index for real monthly volume and average cost per click. No stored averages, no made-up demand.
We divide to get people, never multiply
One buyer searches the same decision several times, so unique people are always fewer than searches. We divide by a repeat factor that runs from about two for a quick local purchase to fifteen for a considered business one.
We adjust the click price in tiers
ChatGPT Ads needs roughly three dollars a click to clear its auction. Above that, clicks currently run twenty to forty-five percent under Google. Below it, we tell you ChatGPT may cost more, rather than quoting a discount that does not exist.
We cross-check from inside ChatGPT
A second estimate built from OpenAI's own figures: how many people use ChatGPT, how many are on ad-carrying tiers, how much of what they ask is about buying something, and how often an ad appears. Every coefficient is shown with its source.
We say when the data is thin
Some topics live inside ChatGPT and barely touch Google. When the demand data is weak we label the result thin rather than dressing a guess up as a measurement.
The full picture of what ChatGPT ads cost, from the accounts we run, is in our ChatGPT Ads cost guide.
[ Questions ]
Where does the audience number come from?
Live Google keyword volume for the searches your description implies, divided by how many times one buyer typically searches that kind of decision. The divisor is shown in the result, and the second estimate on the report starts from ChatGPT's own user figures instead, so you can see both.
Why use Google data for a ChatGPT tool?
Because no public index of ChatGPT conversations exists. Google search volume is the best available signal for how much demand a topic carries. We use it for the size of the topic, and ChatGPT's own numbers for how much of that is actually reachable inside ChatGPT.
How accurate is the cost per click?
It is a planning range, not a quote. It is anchored on the click prices we see in the ChatGPT ad accounts we run, adjusted per keyword band. The auction is young and has already repriced sharply once, so treat any number here as current rather than settled.
How many estimates can I run?
One to start, and three more from the report we email you. After that, the platform waitlist is the way in.
Is this financial or performance advice?
No. It sizes an opportunity so you can decide whether to test it. What a campaign actually returns depends on your offer, your landing page and your creative.
Worth testing?
Then the next question is who builds the campaign.
We run ChatGPT ads on OpenAI's ad platform with early access most agencies do not have. Live within 48 hours of kickoff.
