YouTube announced the start of a Beta test for a feature called Top Fans — a set of tools to help YouTube creators identify, understand, and interact with their most engaged and influential viewers. This feature is available to all creators worldwide with at least 500 subscribers.
So, how does this Top Fans feature work? First, you’ll want to hit up the Community tab in the YouTube dashboard. From there, you’ll see a table that lists your most engaged fans. This list is updated daily, and you can sort it by any number of metrics, comments, likes and shares.
