Definition: Userrank is a measure based on user engagement that evaluates social media performance for brands, with a focus on how well they reach and engage their audience. It helps to determine the effectiveness of a brand's social media strategy in terms of acquiring, retaining, and driving new followers. The word comes from Greek "user" meaning "person," and "rank" is a measure or ranking system, usually based on activity (e.g., likes, comments) that an individual receives or posts on social media platforms.
