Google Discovery Ads Campaign Powered By Custom Intent Audience Targeting

Discovery ads use your audiences to target ads across the Google display network, including Google’s Discover feed, YouTube, and Gmail. This campaign type uses automated bid strategies to drive transactions at the lowest possible cost, and can be useful especially for retargeting and in-market, and custom intent audiences. 

A custom intent audience combines several targeting factors, such as search queries and competitor URLs, to find people who are relevant to your business. Think about pulling a search terms report and add in any relevant themes, together with relevant competitors to ensure maximum relevancy.
