What’s one practical application for YouTube Analytics for Artists?

The correct answer is understanding which of an artist’s songs are fan favorites to include them on a tour setlist. YouTube Analytics for Artists provides data on song performance, including audience engagement and popularity, which directly informs setlist decisions for live performances. The other options are less direct or practical applications: Running ad campaigns for fan-favorite videos is possible but not the primary, most practical application of identifying fan favorites for an artist's strategic planning. While understanding search terms is useful for optimizing video metadata, it's a broader SEO strategy rather than a direct application of identifying "fan-favorite songs" for performance. Estimating new video performance based on general YouTube trends is speculative and doesn't utilize the artist-specific fan favorite song data provided by YouTube Analytics for Artists.
