Maximize Conversions is an automated bid strategy in ChatGPT Ads that lets OpenAI set and adjust your bids to win as many conversions as possible from your daily campaign budget. It differs from a fixed bid, where you set a manual click bid yourself and OpenAI never moves it.
On a conversions campaign, this strategy decides whether a human guesses bids every day or the system optimizes them toward your tracked conversion event. Pick it without working conversion tracking in place and OpenAI has no signal to optimize against, so your budget chases clicks that never convert.
Maximize Conversions sits on the ad group inside a ChatGPT Ads conversions campaign, where it replaces a manual click bid with OpenAI's own bidding. OpenAI calls it one of two Maximize Results strategies, alongside Maximize clicks, and both ask the platform to get the most of a chosen result from a daily budget. With this strategy, the result OpenAI chases is your campaign's selected conversion event.
Three things have to be true for it to run. The campaign objective must be Conversions, the campaign needs a daily budget instead of a lifetime one, and you omit the manual bid cap so OpenAI controls the bid. You also attach exactly one active standard conversion event, and audience bid multipliers are off because they only work with fixed bids.
The strategy pairs with conversion-optimized cost per click, so billing happens on valid clicks and you never pay per conversion. That makes it the automated counterpart to setting a conversion bid cap by hand.

The strategy only works once a few pieces are in place, and then it runs the same loop on every auction.
Set up tracking: Install the ChatGPT Ads pixel and the Conversions API, then create one standard conversion event so OpenAI can see what counts as a conversion.
Build the campaign: Create a campaign with the Conversions objective and a daily budget, and attach that single active conversion event.
Pick the strategy: On the ad group, set the bid strategy to maximize conversions and leave the manual bid cap empty so OpenAI owns the bid.
Let it bid: For each eligible conversation, OpenAI raises or lowers the bid toward clicks it judges likely to convert, spending within your daily budget.
Review results: Conversions report back through your pixel and Conversions API, and you watch spend and delivery in the Insights reporting.
The output tells you how many conversions the budget bought and at what cost per result. It does not promise a fixed cost per acquisition, since billing still lands on every valid click.
The choice between automated and manual bidding decides how much of your ChatGPT Ads budget turns into tracked conversions instead of wasted clicks. ChatGPT Ads is now a performance channel, and on a performance channel that choice is the difference between a line item you can defend to finance and one you quietly cut next quarter.
Bids move faster than you can: OpenAI re-prices every eligible auction in real time, which a person adjusting a manual bid once a day cannot match, especially as demand and competition shift through the day.
It protects the budget you already committed: the strategy spends toward your conversion event within the daily cap, so money flows to conversations likely to convert instead of sitting idle.
Weak tracking breaks it: with no working pixel or Conversions API, OpenAI optimizes against missing data, and spend drifts to clicks that never convert while reports look empty.
SEO managers use Maximize Conversions to turn ChatGPT Ads conversion campaigns over to automated bidding while they focus on landing page and query work.
Growth marketers use Maximize Conversions to scale spend on a new channel without hand-tuning a bid every morning.
Demand gen leads use Maximize Conversions to push a daily budget toward sign-up and demo events their pixel already tracks.
A conversions campaign optimizes toward exactly one active standard conversion event that you select, and custom events cannot serve as the optimization goal, so the event you pick defines what Maximize Conversions actually chases and what shows up in your reports over time.
Maximize Conversions only runs on a campaign with a daily spending limit, because the system needs a repeating daily ceiling to pace automated bids against, and a lifetime budget is not compatible with it at all.
Billing happens on valid clicks even though the goal is conversions, so Maximize Conversions optimizes delivery toward likely converters while your actual cost per conversion stays uncapped, which shapes how you read results each week.
Hand bid-setting to OpenAI so your daily budget targets conversions automatically without daily input.
Spend across ChatGPT Ads placements on iOS, Android, and web from one strategy.
Free your team from adjusting a manual bid every day.
Optimize toward the exact conversion event your pixel and Conversions API report.
Switch back to a fixed bid whenever you want manual control again.
Turn on the pixel and Conversions API before you launch, because the strategy is only as good as the conversion data it sees.
Give the campaign one clear conversion event, so OpenAI optimizes toward the action that matters to revenue.
Set a daily budget you can sustain, since automated bidding will spend toward the full cap to find conversions.
Let the strategy gather data for several days before you judge it, because early bids are noisier than settled ones.
Keep a separate manual-bid ad group when you need a hard ceiling, so you hold control where cost certainty matters.
Review spend and cost per result in Insights weekly, and pause or adjust when results drift.
Avoid flipping the strategy on with broken or missing conversion tracking. Without events flowing back, OpenAI optimizes against nothing, your budget drains into low-intent clicks, and the reports give you no way to see it happening.

Maximize Conversions lets OpenAI set and adjust ChatGPT Ads bids to win conversions from a daily budget automatically.
You run it on a conversions campaign with one active conversion event and no manual bid cap.
It requires a daily budget and working conversion tracking, which are the hard constraints on using it well.
Billing stays on valid clicks, so a broken pixel quietly sends spend to clicks that never convert.
The leverage is in the conversion event you choose, since that signal is what the system optimizes toward.
The core difference is who sets the bid: with a fixed bid you enter a manual amount and OpenAI holds it there, while Maximize Conversions hands bid control to OpenAI. A fixed bid works on impressions, clicks, or conversions campaigns, and you can adjust the number yourself whenever you want a tighter ceiling. Maximize Conversions only runs on a conversions campaign, needs a daily budget, and asks you to omit the manual bid cap entirely. Because OpenAI controls the bid, it can raise or lower what you pay per auction to chase the conversion event you selected, something a static manual number cannot do. The trade is control for automation: a fixed bid gives you a hard limit on each bid, while Maximize Conversions gives you automated pacing toward conversions with no guaranteed cost per result. Many advertisers run both, keeping one ad group manual for certainty and one automated for volume.
Give it at least several days before you read the numbers, because automated bidding needs a run of conversion data before it settles. In the first day or two, bids swing while the system learns which conversations lead to your event, so early cost per result often looks worse than it will later. A practical window is to wait until the campaign has gathered a meaningful count of real conversions on the chosen event before you change anything. Resist editing the budget or event mid-learning, since each change restarts how the system paces bids. Check delivery in Insights during this period to confirm the ad group is actually spending and not blocked by a review or targeting issue. Once results stabilize, compare cost per result against your manual benchmark and decide whether to scale the daily budget or hold it.
Cost per conversion moves because Maximize Conversions never caps it, and OpenAI bids into a live auction where demand, competition, and your conversion signal all shift. The strategy optimizes toward your event, but it bills on valid clicks, so the amount you pay for each conversion depends on how many clicks it took to get one. When your conversion volume is thin, the system has less signal and spends more exploring, which pushes the cost around. Auction pressure changes by time of day, audience, and inventory, and a product-feed campaign behaves differently from a standard one. Tracking quality matters too, since conversions reported late through the Conversions API can make a good day look expensive until the data catches up. The practical read is to judge cost per result over a settled window of several days, where these swings average out, instead of reacting to a single volatile day.
No, and that is the point of the strategy: once you choose Maximize Conversions you omit the manual bid cap, and OpenAI sets each bid on its own. What you can control are the inputs the system optimizes around. You choose the conversion event, so pick the one closest to revenue. You set the daily budget, which is the ceiling the bidder paces against. You shape eligibility through targeting and the platforms you allow, and you decide the quality of the conversion signal by keeping your pixel and Conversions API healthy. You cannot set a per-auction bid or add audience bid multipliers while this strategy is active, because those only work with a fixed bid. When you need a hard cost ceiling on each bid, switch that ad group back to a fixed bid, or run a second manual ad group alongside the automated one. Control here is indirect: you steer it through budget, event, and targeting while OpenAI owns the bid.
A good result is a cost per conversion that beats what your manual bidding produced for the same event, at equal or greater volume. Because the strategy publishes no target cost per acquisition, your own prior performance is the benchmark that matters more than an absolute number. Set a baseline first: run a manual conversion bid for a few days, record the cost per result and the conversion count, then switch one ad group to Maximize Conversions and compare over a settled window. Good looks like steady or rising conversions with a flat or falling cost per result, and spend that stays inside your daily budget. Watch the conversion count alongside the cost, since a cheaper cost per result on far fewer conversions is rarely a win. When the automated ad group cannot match your manual cost after it has settled, hold spend on the manual setup and revisit your event choice and tracking before trying again.
