Sofia wants to find new audiences that have similar attributes to her existing customers. Which targeting method would she use?

Lookalike Audiences are the correct choice because they allow advertisers to reach new users who share characteristics with their existing customer base. LinkedIn's algorithm analyzes the attributes of a source audience (e.g., website visitors, customer lists) and then identifies a broader audience with similar professional traits, skills, and interests. This expands reach while maintaining relevance. Audience Attributes, while a targeting option, refers to selecting specific demographic or professional characteristics (like job title, industry, or seniority) directly, rather than finding new users based on the similarity to an existing group.
