What is the Relevance metric and how is it calculated? 

Relevance is a proprietary Winnin metric that measures how much a piece of content is consumed compared to others.

To ensure a fair comparison between content of different ages, the index is calculated based on engagement on the 7th day after publication (called E7).

This engagement includes interactions like likes, comments, and shares, with variations by platform (on Twitch, for example, only views are counted). The index is displayed as a line graph showing how a topic relevance evolves over time. Importantly, it uses all videos within a given subject for the calculation, not just the most popular ones.
