What do you need before creating a lookalike audience in Campaign Manager?

To create a lookalike audience in Campaign Manager, having a contact list or website audience is essential. This requirement stems from the core concept of lookalike audiences, which are designed to mirror the characteristics of an existing audience. By providing a contact list or a website audience, you enable LinkedIn to analyze the traits and behaviors of this initial group. The platform can then leverage its data to identify and target new individuals who share similar demographics, interests, and professional behaviors, increasing the potential effectiveness of your ad campaigns.

The other choices, while important for different aspects of marketing and advertising efforts, do not specifically facilitate the creation of lookalike audiences. Ad performance data may help you refine existing campaigns but does not provide the necessary foundation for building a new lookalike audience. A social media followers list lacks the required granularity that contact lists or website audiences have, as those lists directly feed into the matching process. Lastly, budget confirmation is necessary for launching campaigns but is not relevant to the audience-building process itself.
