Early reading. We have captured 2 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 310 interactions against 4.4M followers, an engagement rate of 0.007%. Measured over 2 original posts, its engagement rate beats 12% 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 324K times each, and 0.096% of those impressions turn into an interaction. That is about 7.34% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.1 posts a day over the last 30 days, though only 7% of days saw any activity at all. Most posts go out around 13:00 UTC, and Tuesday is the busiest day of the week. Of the 2 posts sampled, 50% carry an image or video, 50% are part of a thread and 50% link out. The account's strongest tracked post pulled 39K interactions, about 125x its own typical post. Only 2 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.

Engagement rate as a share of followers, across the 36,261 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 107,137 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 13:00 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.

    Jersey City + BDS. Antisemitism isn’t abstract. It’s real, it’s rising in NY and NJ, and it demands leadership - not silence or equivocation. I’ve dealt with this directly as Mayor of Jersey City, and I’ll be just as vocal as I step into my role as CEO of the Partnership for NYC later this month.

    Today, we dosed the first participant in VESPER-5, our second Phase 3 obesity study in just a few months. At least ten pivotal studies are planned for our lead investigational treatment this year, with more than 20 across our ambitious pipeline. We said we'd move fast after acquiring Metsera. We meant it.

What is Albert Bourla's engagement rate on X?
Albert Bourla (@AlbertBourla) has an engagement rate of 0.007%, based on the median interactions across 2 original posts from the last 30 days against 4,413,358 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.007%, Albert Bourla sits above the 10th percentile of the 36,261 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
Does @AlbertBourla have real engagement?
Its engagement rate beats 12% of the tracked X accounts closest to it in follower count, which puts it in the bottom quarter for its size group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
When does @AlbertBourla post?
Most posts go out around 13:00 UTC, and Tuesday is its busiest day, at roughly 0.1 posts per day across the measured window.
