Engagement
Early reading. We have captured 1 original post for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 137 interactions against 2.2M followers, an engagement rate of 0.006%. Measured over 1 original post, its engagement rate beats 21% of tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 14K times each, and 0.983% of those impressions turn into an interaction. That is about 0.627% of the follower count, which is the gap between an audience on paper and an audience in a timeline.
Measured over 1 original post from a 30-day window, last computed on September 5, 2026.
