Create a Lookalike audience based on a Custom audience in Meta

In order to profile your audiences in the SOPRISM platform, we strongly recommend that you create a lookalike from your custom audience.

There are two ways to access the lookalike creation menu:

You have just finished creating a Custom audience, and you have the option that appears directly in the pop-up menu
You select a previously created custom audience available in the list, the action button allows you to access the option

👉 Whatever your point of entry, the following steps are the same.

Select or make sure you have selected the right source for your Lookalike audience.
Choose a geolocation (you don't have the geolocation option?)
Choose a % to create a Lookalike to stay as close at possible from your Custom audience.

Once you have specified the geolocation and chosen the percentage, you have a view on the estimated size of the final audience.
✅ Make sure your audience is big enough to get meaningful insights.

Click on "Create Audience"

From now on, you can find your audience in your list.
Wait until it has finished populating and the size estimation shows a figure.

The next step is to import your Lookalike audience into the soprism platform to create a project based on first party data.
