Look-alike
Look-alike is a type of audience in digital marketing that is formed based on an existing user database and includes people who are maximally similar to it in terms of behavior, interests, and characteristics.
What is Look-alike?
Look-alike is a technology for selecting a new audience that resembles current customers or users in its attributes. Advertising systems analyze the original base (seed audience) and find users with similar behavioral patterns.
Such audiences are actively used in targeted advertising and performance marketing.
How is a Look-alike Audience Formed?
- Selecting the Source Audience: This could include:
- customers;
- leads;
- website visitors;
- users who have completed a targeted action.
- Data Analysis: The system analyzes demographics, interests, behavior, and user actions.
- Finding Similar Users: Algorithms select a new audience with maximum similarity.
Where is Look-alike Used?
- in targeted advertising;
- when scaling advertising campaigns;
- for attracting new customers;
- on social networks and advertising platforms;
- in performance marketing.
Advantages of Look-alike
- rapid scaling of traffic;

Factors Affecting the Quality of Look-alike

Limitations of Look-alike
