Set target CPAs for ad groups

Google Ads offers an automated bid strategy that automatically sets bids to help you get as many conversions as possible within your budget: target CPA bidding. To use target CPA, you set a target cost-per-action (CPA) that is then used to automatically optimise bids for all campaigns and ad groups using your bid strategy.

To give you more control over your target CPA bid strategy, you can set an ad group target CPA that overrides the target CPA of the overall bid strategy. This article shows you how to set an ad group target CPA.

Before you begin

If you haven't set up a target CPA bid strategy, read about target CPA bidding first. 


  1. Sign in to your Google Ads account.
  2. From the page menu on the left, click Ad groups.
  3. Find an ad group that uses a target CPA bid strategy.
  4. Click the number in the 'Target CPA' column.
  5. In the dialogue box that appears, enter your desired ad group target CPA.
  6. Click Save.

Bear in mind

Setting an ad group target CPA might affect the overall performance of your target CPA bid strategy. While an ad group target CPA gives you more control over the performance of one ad group, it might impact the ability of your bid strategy to meet its overall target CPA.

Ad group target CPAs persist even when you change the strategy target CPA. Changing the target CPA of the whole bid strategy will not change any ad group target CPA you may have already set within that strategy. To change an ad group’s target CPA back to the bid strategy default, you’ll have to remove it manually.
