About Maximise conversions bidding

Maximise conversions automatically sets bids to help get the most conversions for your campaign while spending your budget. It uses advanced machine learning to automatically optimise bids and offers auction-time bidding capabilities that tailor bids for each and every auction. This article explains how Maximise conversions works.

Before you start

If you don’t yet know what type of automated bid strategy is right for you, read About automated bidding first. 

Before you can set up a Maximise 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, Maximise 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 Maximise conversions:

  • Check your daily budget amount. Maximise conversions will try to fully spend your daily budget, so if you’re currently spending much less than your budget, Maximise conversions could increase spend significantly. 

  • Check your ROI goals. If you have an ROI goal for your campaign, such as a target cost per action (CPA) or return on ad spend (ROAS), you may want to switch to a Target CPA or Target ROAS bid strategy. Like Maximise conversions, these strategies automatically set bids for each auction, but the goal will be to achieve the average CPA or ROAS target that you set, rather than spending your full budget to maximise conversions.
