Kim is seeing significant performance from her Google Display remarketing campaign, and wants to expand upon it. Which targeting option should she choose to accomplish this?

Similar Audiences is the best choice because it allows Kim to reach new users who share characteristics with her existing remarketing audience. This expands her reach beyond those who have already interacted with her business, leveraging the success of her current campaign to find new, high-potential customers. In-Market audiences target users actively researching products or services, which is broader than expanding on an existing remarketing list. Demographic targeting focuses on age, gender, and parental status, which doesn't directly leverage the behavior of her remarketing audience. Custom Intent audiences target users based on specific keywords or URLs, which is a different strategy than finding lookalikes of her current successful audience.
