Enhanced Lookalike Audience Capability

Gemini now provides you with an enhanced Lookalike capability in the UI for greater control and insight of your lookalike audience campaigns.

Using Lookalike audiences, you can target a group of users who have similar web browsing or buying habits as your current customers.

You navigate to Shared Library > Custom audiences > Get started and select Lookalike audience as your objective.

How It Works

Once you enter the Audience name you want to reach your customers, you’ll be able to specify the source for your custom audience, as well as its size.

Hovering over the source, you’ll be able to view the seed size for your Lookalike audience.

Important

If the source has a seed size less than 1,000, you won’t be able to create a Lookalike campaign. The Gemini UI includes a new guard rail that ensures you’ll have enough sample data when modeling the output.
