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 behaviour to your existing remarketing list members.
If you use Customer Match, using similar segments may benefit you to help expand the reach of your lists to more users for the purpose of new customer acquisition or expansion of your advertising campaigns.
Benefits
- 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 recent search activity of the visitors in your remarketing list to help aggregate search behaviour of the visitors in your list. Based on this information, the system automatically finds new potential customers whose search behaviour 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 segments 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 segments will then find other people with similar search behaviour, such as people who searched for 'buy lightweight running shoes'.
Your similar segments 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 segment list after it gets created.
Qualifying for similar segments
To find similar segments, Google Ads looks at the millions of people searching on Google. The system will automatically identify which of your remarketing lists qualify for similar segments 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 behaviour
- Any adjustments made to the original list
A similar segments list is created from a remarketing list or Customer Match list with at least 1,000 cookies with enough similarity in search behaviour to create a corresponding similar segment. Learn more about how Google Ads collects user information
Website tag and rule-based remarketing lists, as well as Customer Match lists built from email addresses, mailing addresses and/or phone numbers, can be used to generate similar segments. 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 Audience manager.
Bear in mind
Similar segments do not use sensitive information, such as search activities based on race, religion, sexual orientation or health. Learn more about our Personalised advertising policy
People who don't want to be included in similar segments are able to opt out through their Ads Settings.
