Maximize Conversions is an automated Smart Bidding strategy in Google Ads that aims to generate as many conversions as possible within your available budget.
Instead of focusing on individual bids, Google’s algorithm automatically adjusts bids in real time based on the likelihood that a click will result in a conversion.
How Maximize Conversions works
Google Ads uses machine learning to evaluate signals such as device, location, time of day, user behavior, and intent. Based on these signals, bids are increased or decreased for each auction to capture conversion opportunities.
The system prioritizes volume, not cost per conversion.
When to use Maximize Conversions
This bidding strategy works best when:
- Your main goal is conversion volume
- You have a flexible CPA
- Your budget is limited or fixed
- Conversion tracking is set up correctly
- You have enough historical conversion data
It is often used in lead generation and early growth phases.
Maximize Conversions vs Target CPA
Maximize Conversions focuses on getting the most conversions possible, even if the CPA fluctuates.
Target CPA adds a cost control layer and aims to keep the average CPA around a set target.
Many advertisers start with Maximize Conversions and switch to Target CPA once enough data is available.
Things to keep in mind
- CPA can increase if budget allows it
- Budget limits strongly influence performance
- Not ideal when strict cost control is required
- Best combined with high-quality conversion signals
In short
Maximize Conversions helps you get the highest number of conversions by letting Google automatically optimize bids across auctions.
