Measured over 8 original posts from a 30-day window, last computed on October 25, 2026.
Engagement
A typical post picks up 84 interactions against 4.9M followers, an engagement rate of 0.002%. Measured over 8 original posts, its engagement rate beats 15% of 20,444 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 58K times each, and 0.145% of those impressions turn into an interaction. That is about 1.18% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.53 post a day over the last 30 days, though only 30% of days saw any activity at all. Most posts go out around 19:00 UTC, and Wednesday is the busiest day of the week. Of the 8 posts sampled, 50% carry an image or video, 13% are part of a thread and 38% link out. The account's strongest tracked post pulled 39K interactions, about 444x its own typical post. Recurring topics include #standuptojewishhate, #standuptohate.

Compared with accounts its own size
Albert Bourla's engagement rate beats 15% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 10% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 19:00 UTC, and Wednesday 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.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 50% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 38% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 50% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 38% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 380 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

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 0.002%, based on the median interactions across 8 original posts from the last 30 days against 4,921,672 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.002%, Albert Bourla sits below the 10th percentile of the 204,694 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 15% of the tracked X accounts closest to it in follower count (20,444 accounts), 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 19:00 UTC, and Wednesday is its busiest day, at roughly 0.53 posts per day across the measured window.
