You’ve already put real money into Google and Meta. Now every newsletter in your inbox says ChatGPT ads are the next big channel, so you open Ads Manager, set a max bid and hope for the best.
That hope has an expiry date. OpenAI is retiring Max Bid and Max CPC on January 1, 2027, and Target CPA arrives for new conversion campaigns on November 9.
Here’s how to set up ChatGPT ads the way we would: tracking first, Target CPA second, budget last.
To keep your campaigns scalable ahead of the January deadline, run your new Target CPA strategy alongside existing Max Bid setups as a side-by-side test. Focus on building tightly themed ad groups with natural-language context hints, monitoring performance daily using a single dashboard. This controlled transition protects your budget, ensures clean optimization data, and positions your business to capture high-intent audiences without suffering performance drops or wasted ad spend.
ChatGPT ads aren’t a pilot anymore. OpenAI says ads are now available in 89 countries and that more than 100,000 advertisers have used the platform. The OpenAI ads platform is a real channel with a real self-serve ChatGPT Ads Manager.
And a lot of advertisers are walking into it with a Google Search playbook.
Here’s the mistake waiting to happen. You build a keyword list, set the highest bid you can stomach, and skip conversion tracking because you’ll sort it out later. That’s not a strategy. That’s a donation.
ChatGPT doesn’t match ads to typed queries. Each ad group carries context hints, which are plain-language descriptions of the conversations your ad fits. OpenAI is explicit that they aren’t exact-match keywords and don’t guarantee delivery in any specific conversation.
Then there’s the money. ChatGPT ads cost depends on an auction. With Intelligent bidding, Target CPA or Target CPC, OpenAI’s system weighs the likelihood of a click or conversion against the price it would pay and sets bids for you.
There’s a floor, too. The minimum daily budget is $25 in US dollars per campaign, with different minimums in other currencies. That makes ChatGPT ads for small business a realistic test, since you don’t need an enterprise budget to start.
But a small budget also hands the algorithm very little data to learn from.
Cheap to enter doesn’t mean cheap to get wrong.
Here’s the part most guides skip. Target CPA doesn’t make bidding easier. It moves the work.
With Max Bid, you set a cap and the platform worked underneath it. With Target CPA, you tell OpenAI the average you’d like to pay for a conversion, and the system decides what to bid in each auction. The target isn’t a fixed price. Your actual average CPA can land above or below it.
So what steers the algorithm? Your conversion data.
OpenAI’s own guidance for conversion campaigns is to confirm that your Pixel or Conversions API is receiving the event you selected, then review your Event Quality Score and Diagnostics in Ads Manager for gaps. That’s in the same bidding help article that announces Target CPA.
Think of your bid as the doorbell and your tracking as the camera. If the camera is blurry, the algorithm can’t tell a buyer from a browser. Feed it junk and it’ll chase junk, very efficiently.
One more thing most people get wrong: set the target from your real results, not a wish. If you spent $400 and got 10 purchases, your CPA is $40. A $20 target on a $40 result won’t buy purchases at half the price. OpenAI warns it can restrict delivery instead.
Your target is a goal. Your tracking is the steering wheel.
At the $25 daily minimum, one campaign running a full month costs roughly $750. That’s the price of finding out your setup was wrong, so let’s not pay it twice.
If you want to know how to advertise on ChatGPT without wasting that first month, here’s the order we’d run it in. Here’s how to set up a ChatGPT ads campaign, step by step:
To use self-serve Ads Manager, the legal entity that advertises and gets billed has to be based in a listed country. OpenAI’s latest expansion added markets including Argentina, Chile, Colombia, Peru, Nigeria, South Africa, Serbia, Ukraine, Cambodia, Bangladesh and Pakistan, and it says advertisers can reach ChatGPT Ads through technology partners or self-service. Check which one applies to you before you build anything.
Your Pixel ID and Conversions API key both live in the Conversions section of Ads Manager. Run both. The browser pixel catches what happens on the page, and the server-side API catches what the browser drops. Send the same event ID from each so the platform can match them instead of double-counting. OpenAI keeps the setup guides and supported events on its developer site for ChatGPT Ads. If your tracking is shaky, behavioral tracking is where we’d start.
Pick your conversion event (a purchase for a store, a lead for a service business), your countries and your budget. OpenAI recommends new advertisers start with a daily budget so they can watch delivery before committing to a campaign total. Daily spend won’t exceed twice your daily budget, so size the test as money you can afford to lose at zero conversions.
Divide spend by conversions from your existing channels over a steady period, then start near that number. OpenAI’s own example shows how targets can be weighted: a $50 Target CPA with a 1.2x new-customer multiplier gives that segment a $60 target. Don’t set a number you wish were true.
One theme per ad group. OpenAI says to keep each ad group focused and to split meaningfully different products, audiences or use cases into separate groups. Write context hints as descriptive phrases, like “a founder comparing ad platforms for a Shopify store,” rather than single words. Then make sure the landing page answers the same conversation. That’s conversion rate optimization work, not ad work.
A target is an average, so one number won’t tell you the story. Put spend, results and average cost in one view, ideally a live marketing dashboard, so drift shows up in days instead of on the invoice.
Skip step two and every other step gets more expensive.
If you started running ChatGPT ads before November, you’re probably on Max Bid or Max CPC. Here’s the timeline that matters:
One more change worth knowing. Maximize results, the old autobid option, is now called intelligent bidding, and it needs no target at all. If you don’t have enough conversion data for a sensible Target CPA yet, that’s the honest place to start.
Don’t wait for the switch to be forced on you. Run a Target CPA campaign beside your current one for a few weeks and compare CPA and spend before January.
A deadline you test against is a plan. A deadline you ignore is an invoice.
Everyone wants a winner. We’d rather show you the differences, because they change how you should spend.

What the target means | An average-cost goal, not a fixed price. Actual CPA can run higher or lower | |
Hard bid limits | Max Bid and Max CPC retire January 1, 2027 | Optional bid limits, available on portfolio Target CPA strategies |

Here’s our read. Google catches people who already know what they want. ChatGPT catches people mid-conversation, still weighing options. That’s a different job, so judge it on a different scorecard: new-customer CPA and assisted conversions, not just last-click ROAS.
Don’t cut a winning Google campaign to fund a ChatGPT test. Carve out a capped slice instead. And if your Google campaigns are already starving for conversion data, fix that first. Here’s how we’d fix Performance Max with under 15 conversions.
If you want a second opinion on your search setup, that’s what our Google Ads and search campaign work is for.
Test ChatGPT beside Google. Don’t bet against either one.
That’s the order we work in at THEMAYK on every paid media account: tracking, then funnel, then spend. ChatGPT ads don’t change that. They make it matter more, because Target CPA only works when the data underneath it is clean.
If you can’t say where leads drop between the click and the sale, a sales funnel breakdown comes before any new channel. And if your numbers live in four different tabs, a business and website analytics setup fixes that first.
