Plays per post is the typical number of views a creator's videos reach, based on the actual view counts that TikTok publishes.
influData uses the median rather than the mean, so a single viral hit does not inflate the value — the median shows the reach a brand can realistically expect from an average video.
In the app this value also appears as Expected Audience per Post: an estimate of how many users a single post will reach, which is exactly what matters when you plan a collaboration. Reach is usually more decisive for the success of a campaign than the follower count. Keep in mind that plays often vary strongly between videos, and sponsored posts frequently reach a smaller audience than organic posts, so treat the value as a rough guide rather than a guarantee.
