For most small businesses, watch for now, and don’t move your budget yet. [Notebook](https://dumbcmo.com) › [Blog](https://dumbcmo.com/blog) › Paying to be seen › ChatGPT ads: how they pick who shows, in plain English Imagine asking a friend which sofa to buy, and halfway through the answer a shopkeeper whispers, “try mine”. That’s ChatGPT ads, more or less. ## In normal-people words On 22 October 2026, Search Engine Journal summarised how OpenAI says ads in ChatGPT work. In short: - A separate model reads the conversation and turns the relevant parts into search queries. - It finds ads that match the **meaning** of the conversation, not just exact keywords. - Ads must pass checks for location, policy, budget and pacing. - An auction decides ranking and price. The language model helps pick who enters, but doesn’t choose the winner or set the price. - A final check confirms the ad actually suits the conversation. A winning ad can still go unshown, for example if it misses the delivery window. OpenAI says more than 100,000 advertisers have run ads, and that ads reached a projected pace of $1 billion a year in under 200 days. That’s a projection, not money collected. > **The DumbCMO:** Same old game, new venue. Somebody always finds a way to charge you for the whisper. ## Should a small business bother? **Your move** - **If** You already get customers from Google Ads or Instagram ads **→ then** Keep going. Don’t shift budget on a hunch. - **If** Your customers ask AI tools for recommendations **→ then** Worth a small test later, with money you can lose. - **If** Someone is pitching you “ChatGPT ads management” already **→ then** Ask for their own results, not OpenAI’s numbers. **What we know and what we don’t** | Question | Answer so far | | --- | --- | | Is there an auction? | Yes, separate from the language model | | Does it match on meaning? | Yes, not only exact words | | What does a click cost? | Not stated in the explainer | | Any published ROAS or conversion benchmarks? | None in the explainer | ## The chai stall version A new corner opens beside your chai stall. Posters say it gets amazing footfall. Nobody has told you the rent. **Don’t sign the lease before you’ve seen the numbers.** ## Do this today - [ ] Ask a few real customers whether they ask ChatGPT for recommendations before buying. - [ ] Write down your cost to win one customer. If you don’t know it, read the [CAC and LTV explainer](/blog/cac-and-ltv-explained) first. - [ ] Set a test budget you could happily lose, if you do try it. - [ ] Ask anyone selling you this for real results from businesses like yours. ## Not-so-frequently asked questions ### Do ChatGPT ads use my private chats? OpenAI says the system can use earlier messages in a conversation, and non-sensitive details from past chats for people who opt into personalised ads. ### Is this replacing Google Ads? No. It’s another place to advertise, and it’s early. ### Can I buy these ads in India? I couldn’t confirm availability by country. Check OpenAI’s ads information before planning anything. ## Things your agency won’t say - “Be first on ChatGPT” is a pitch, not a plan. Early doesn’t mean cheap or profitable. - $1 billion is OpenAI’s revenue pace, not your return on ad spend. - Test small, measure sales, then decide. ## Jargon Jail **Locked up: “Auction”** How ad platforms decide who shows and what they pay. **It’s a bidding system that also weighs how good your ad is for the person.** ## Where to go next - The basics: [What are paid ads?](/blog/what-are-paid-ads) - Where to start: [Google Ads for beginners](/blog/google-ads-for-beginners) - Compare: [Instagram ads or Google ads?](/blog/instagram-ads-or-google-ads) ## Sources 1.
