What is the primary algorithmic factor, beyond page views, that dramatically influences an IMDb Starmeter ranking?

The primary algorithmic factor beyond page views that significantly influences an IMDb Starmeter ranking is the frequency and recency of being added to IMDb user watchlists. While page views reflect general interest, inclusion on watchlists indicates a higher level of engagement and intent to follow an actor's or filmmaker's career closely. The more frequently and recently an individual is added to watchlists, the greater the positive impact on their Starmeter ranking. This signals to the algorithm that the individual is not only being viewed but is also considered someone to actively track and receive updates on, signifying a higher level of fan engagement and industry attention than just casual browsing. Therefore, an increase in watchlist additions typically leads to a more pronounced improvement in Starmeter ranking compared to a similar increase in page views alone.
