ChatGPT Ads is changing how advertisers set cost goals. From Monday 9 November 2026, Target CPA replaces Max Bid for new conversion campaigns that want a specific cost-per-conversion goal. Target CPC becomes available for new click campaigns, replacing Max CPC.
Existing Max Bid and Max CPC campaigns can keep running until those options retire on 1 January 2027. OpenAI recommends beginning the move in Ads Manager from 9 November 2026.
For Adelaide business owners, the key distinction is simple: these targets are average-cost goals, not caps. This update concerns ChatGPT Ads, not Google Ads Target CPA or Target CPC.
What is changing?
The old controls and the new targets serve different purposes. Max Bid sets an auction-bid ceiling, while Max CPC sets a maximum click bid. Target CPA and Target CPC instead tell the system the average outcome cost you would like it to work towards.
Target CPA applies to conversion campaigns. CPA means cost per action: the action could be a lead or purchase. The system uses the target and available conversion signals to adjust bids and delivery towards that average cost.
Target CPC applies to click campaigns. CPC means cost per click. The system can bid above or below the target in individual auctions while working towards the desired average click cost.
Neither setting promises a fixed price. Individual results can cost more or less than the target, and the actual average can also finish above or below it.
What does this mean for an Adelaide business?
Start by checking whether your business actually runs ChatGPT Ads. If an agency or team member manages your advertising, ask them to identify any relevant campaigns and their current bidding settings. Do not assume a reference to “Target CPA” in a report means ChatGPT Ads; confirm the platform first.
If you have existing Max campaigns, there is a transition period. The 9 November start date is the point to begin moving, while 1 January 2027 is the retirement date. Use that window to review the account and plan the change with whoever manages your ads.
Avoid treating an old maximum bid and a new average-cost target as interchangeable numbers. They describe different controls. A useful review starts with what your campaigns have actually achieved and what a lead, purchase or click is worth to your business.
Practical checks before you move
- Confirm the campaign and objective. List any ChatGPT Ads campaigns using Max Bid or Max CPC. Check whether each campaign is intended to generate conversions or clicks, so the planned target matches the outcome you want.
- Review recent actual CPA or CPC. Look at recent conversion costs for conversion campaigns and click costs for click campaigns before choosing a target. Discuss those results alongside your business goals. A target below recent performance may restrict delivery; entering a lower number does not guarantee cheaper results.
- Check conversion tracking and event quality. For conversion campaigns, confirm the OpenAI Pixel, Conversions API (CAPI), or both are set up. Review the Event Quality Score (EQS) as part of that check. Weak or missing conversion signals can reduce delivery, so a tracking review belongs alongside the bidding review.
- Agree on the move with your ads person. Begin transitioning campaigns in Ads Manager from 9 November, with the 1 January retirement in mind. Ask how the proposed target relates to recent actual costs, and talk through any budget changes before making them in a hurry.
Keep these checks together. If delivery is lower than expected, consider both the target and the conversion signals before deciding that a budget change is the answer. A restrictive target or weak tracking can affect delivery, so the budget alone does not explain every result.
A target is not a billing promise
Target CPA describes the cost goal used for bidding. It does not, by itself, mean you are billed only when a conversion happens. The bidding goal and billing event are separate settings.
That distinction matters when reviewing reports or discussing expected costs. Ask your ads person to explain the campaign’s target and billing setup separately, so everyone is working from the same understanding.
What to do now
Check whether this change affects your account, review actual costs and conversion signals, and begin planning the move from 9 November. Existing Max campaigns have until the 1 January 2027 retirement, but the targets should be chosen with care rather than treated as guaranteed maximums.
