Before you can set up a Maximize conversions bid strategy, you’ll need to set up conversion tracking.
How it works
Using historical information about your campaign and evaluating the contextual signals present at auction-time, Maximize conversions bidding automatically finds an optimal bid for your ad each time it's eligible to appear. Google Ads sets these bids to help get the most conversions for your campaign while spending your budget.
Before switching to Maximize conversions:
Check that the campaign is not part of a shared budget. A campaign that uses Maximize conversions needs its own budget.
Check your daily budget amount. Maximize conversions will try to fully spend your daily budget, so if you’re currently spending much less than your budget, Maximize conversions could increase spend significantly.
Check your ROI goals. If you have an ROI goal for your campaign, such as a target cost-per-acquisition (CPA) or return on ad spend (ROAS), you may want to switch to a Target CPA or Target ROAS bid strategy. Like Maximize conversions, these strategies automatically set bids for each auction, but the goal will be to achieve the average CPA or ROAS target you set, rather than spending your full budget to maximize conversions.
