Pfizer Inc. engagement report
@pfizer - 469K followers on X
Measured over 7 original posts from a 30-day window, last computed on August 29, 2026.
Engagement
Early reading. We have captured 7 original posts 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 38 interactions against 469K followers, an engagement rate of 0.008%. Posts are seen about 6.9K times each, and 0.549% of those impressions turn into an interaction. That is about 1.47% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.27 posts a day over the last 30 days, though only 27% of days saw any activity at all. Most posts go out around 19:00 UTC, and Tuesday is the busiest day of the week. Of the 7 posts sampled, 100% carry an image or video and 86% link out. The account's strongest tracked post pulled 86 interactions, about 2.3x its own typical post. Recurring topics include #esccongress, #globalhealth, #hormonehealth. Only 7 original posts have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 19:00 UTC, and Tuesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.
