Maximize conversions automatically sets bids to help get the most conversions for your campaign while spending your budget. It uses advanced machine learning to automatically optimize bids and offers auction-time bidding capabilities that tailor bids for each and every auction. This article explains how Maximize conversions works.
Bid adjustments and Maximize conversions
Bid adjustments allow you to show your ads more or less frequently based on where, when, and how people search. Because Maximize conversions helps optimize your bids based on real-time data, your existing bid adjustments are not used. There is one exception: You can still set mobile bid adjustments to -100%.
Note: If you switch to Maximize conversions bidding, you don’t need to remove existing bid adjustments, because they won’t be used.

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 your average daily budget amount. Maximize conversions will try to fully spend your average 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 install (CPI), target cost-per-action (CPA), or return on ad spend (ROAS), you may want to switch to a Target CPI, 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 CPI, CPA, or ROAS target you set, rather than spending your full budget to maximize conversions.
