You want to reach people based on their interests using your Google video campaign, but you're not looking to build or refresh audiences manually. What audience solution should you use?

Analysis of Correct Answer(s)

• Infinite taxonomy audiences is the correct solution. This term describes Google's comprehensive and automatically generated catalog of audience segments. These audiences are dynamically created and updated by Google's systems based on a massive range of user signals and interests. This allows you to tap into relevant, interest-based audiences without any manual effort to build or refresh them, directly addressing the core requirements of the question.

Analysis of Incorrect Options

• Custom audiences: This is incorrect because it is the primary solution for manually building an audience. You define a custom audience by inputting specific keywords, URLs, and apps that represent your target user's interests, which is the exact opposite of what the scenario asks for.

• Life events: This option targets users based on major milestones like graduating, moving, or getting married. While automated, it focuses on specific life stages rather than the broader, general interests specified in the question.

• Affinity audiences: While these are pre-defined, interest-based audiences (e.g., "foodies" or "sports fans"), the term "Infinite taxonomy audiences" better represents the full, ever-expanding, and automated nature of Google's entire audience system that you can access without manual creation.
