¿Cuál es el principal beneficio de crear una audiencia similar?

Creating a lookalike audience primarily benefits advertisers by expanding their original audience with similar users within Mercado Libre. This leverages machine learning algorithms to identify new potential customers who share behaviors, interests, and purchasing patterns with an existing high-value customer base (e.g., past buyers or frequent visitors). This strategic expansion helps scale campaign reach by finding qualified prospects who, despite not yet knowing the brand, have a high probability of conversion due to their statistical similarity to the advertiser's best customers within the platform. "Impactar exclusivamente a personas que ya compraron" is incorrect because lookalike audiences aim to find new users, not just re-engage existing ones. "Limitar el alcance para campañas de performance" is incorrect as lookalikes are designed to expand reach efficiently for performance campaigns. "Unificar datos de distintas campañas" is incorrect; while data is used, the primary benefit is audience expansion, not data unification across campaigns.
