About similar audiences for Search
Remarketing allows you to reach people who have already visited your site and connect with an audience that's already interested in your products or services. You probably also want to find new visitors for your site, which you can do by finding people who have similar search behavior to your existing remarketing list members.
- Find and target people similar to your site’s visitors
- Simplify finding audiences to target
- Get new potential customers
How it works
Google Ads looks at the search activity in a short time frame around when visitors are added to your remarketing list to understand aggregate search behavior of visitors in your list. Based on this information, the system automatically finds new potential customers whose search behavior is similar to that of people in your remarketing list.
Say you've created a remarketing list of people who bought running shoes from your sporting goods site. Instead of helping you reach broad groups of people interested in "running," similar audiences will identify that people on this list tended to search for "triathlon training" and "buy lightweight running shoes" before coming to your site and making a purchase. Based on this, similar audiences will then find other people with similar search behavior, such as people who searched for 'buy lightweight running shoes'.
Your similar audiences lists will automatically get updated as the original list evolves and people change their search activity. So, you don't need to update the similar audience list after it gets created.
Qualifying for similar audiences
To find similar audiences, Google Ads looks at the millions of people searching on Google. The system will automatically identify which of your remarketing lists qualify for similar audiences based on a variety of factors, including but not limited to the following:
- The number of visitors on the original list
- How recently these people joined the original list
- The similarity of these visitors’ search behavior
- Any adjustments made to the original list
A similar audiences list is created from a remarketing list with at least 1,000 cookies with enough similarity in search behavior to create a corresponding similar audience. Learn more about how Google Ads collects user information here.
Only website tag and rule-based remarketing lists can be used to generate similar audiences. If these sources don't have enough information, you may have to wait for more interactions and search activities. In these cases, the list may appear as "Incompatible" in the Shared Library's Audience manager.
Keep in mind
People who don't want to be included in similar audiences are able to opt out through their Ads Settings.
