Maximize Conversions is a Smart Bidding strategy that spends your full budget to win as many conversions as it can, with no promise about what each one costs unless you add a target.
You pick this when you want volume and you are willing to hand Google the whole budget to chase it. It will spend to the daily limit, pushing bids up wherever it sees a conversion within reach. Early on, before you know your real cost per conversion, this is a reasonable way to gather data and let the system learn what a converting visitor looks like for your business.
You should treat the bare version as a starting point, not a home. With no target, it has no cost discipline, so it keeps buying conversions even as they get expensive. Once you have watched it run and you know your true cost per conversion, you attach an optional Target CPA, and the strategy stops chasing volume at any price and starts respecting a number.
No target means no brakes. With nothing to aim at, Maximize Conversions will spend everything you give it and let cost per conversion drift upward as it reaches for the next sale, which feels fine until you check what each one actually cost. Add a target the moment you have a defensible one, and keep an eye on your budget, because this strategy will always try to use all of it.
It will get you conversions; the question is what you paid for the last few.
