A typical post picks up 84 interactions against 405K followers, an engagement rate of 0.021%. Measured over 26 original posts, its engagement rate beats 45% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 11K times each, and 0.735% of those impressions turn into an interaction. That is about 2.81% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 70% of days. Most posts go out around 12:00 UTC, and Tuesday is the busiest day of the week. Of the 26 posts sampled, 88% carry an image or video, 12% are part of a thread and 69% link out. The account's strongest tracked post pulled 1.4K interactions, about 16x its own typical post. Recurring topics include #yellcornell, #constitutionday.

Compared with accounts its own size

Cornell University's engagement rate beats 45% 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 39% 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.

Where this sits in the catalog

At 0.021%, Cornell University sits above the 10th percentile of the 204,956 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

Engagement rate as a share of followers, across the 204,956 accounts we have scanned enough to measure. The axis is logarithmic, because the top and bottom of this population are about 22,894 times apart and a linear axis would flatten everything below the median into a single point.

Posting timing

This account posts most often around 12:00 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.

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.

This account's posting mix compared with catalog-wide effects
FormatThis accountCatalog effect95% intervalAccounts behind it
Image or video88% of posts+111%+108% to +115%34K
Outbound link69% of posts-41%-42% to -40%32K
Typical length-+15%+14% to +16%32K
  • 88% 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.
  • 69% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
  • Its average post runs 370 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.

    Researchers at Cornell have created an interactive map identifying 1.8 million individual trees in New York City, with a new approach that could optimize the placement of trees for cooling in cities around the world. In the study, researchers identify the types of trees using satellite imagery as well as on-the-ground datasets and 3D data collected with lidar, short for light detection and ranging. The approach was 82% accurate overall and higher for common types of New York City trees. It’s the first ā€œwall-to-wall,ā€ citywide map identifying trees in natural areas and other unsurveyed areas, which together constitute an estimated 65% of the city’s canopy and have not been accounted for on previous maps. The research team will use the map to determine which trees are best for cooling, and the data could inform a host of other planting decisions where the type of tree makes a difference, from reducing allergens to managing invasive pests.

    Scientists found a human genetic element in a poxvirus and discovered it was both an important gene for brain function and a jumping gene capable of moving and inserting itself in genomes. A study published Sept. 24 in Science reports that the gene, called BC200, combines a mix of characteristics that have never been seen before. Read more: https://t.co/6WMros5HnL.

    The biologic drug interferon-alpha can benefit patients with blood cancers called myeloproliferative neoplasms by forcing mutant blood stem cells to become shorter-lived white blood cells, according to a study by Weill Cornell Medicine investigators. Because the broad activity of interferon-alpha can induce significant side effects, developing new focused strategies based on these mechanistic findings could meet an important need in cancer therapy.

    This morning on the Arts Quad, Cornell Republicans and Cornell Democrats joined together to plant American flags in honor of lives lost in the attacks of September 11, 2001. Throughout the morning, the McGraw Tower chimes are tolling to mark when the planes crashed and towers fell, as our community pauses to honor and remember those killed. Our community is also invited to visit the memorial in the Anabel Taylor Hall rotunda dedicated to the 21 Cornell alumni who died on 9/11.

Reading these numbers

A typical post picks up 84 interactions against 405K followers, an engagement rate of 0.021%. Measured over 26 original posts, its engagement rate beats 45% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 11K times each, and 0.735% of those impressions turn into an interaction. That is about 2.81% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 70% of days. Most posts go out around 12:00 UTC, and Tuesday is the busiest day of the week. Of the 26 posts sampled, 88% carry an image or video, 12% are part of a thread and 69% link out. The account's strongest tracked post pulled 1.4K interactions, about 16x its own typical post. Recurring topics include #yellcornell, #constitutionday.

What is Cornell University's engagement rate on X?
Cornell University (@Cornell) has an engagement rate of 0.021%, based on the median interactions across 26 original posts from the last 30 days against 405,025 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.021%, Cornell University sits above the 10th percentile of the 204,956 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 @Cornell have real engagement?
Its engagement rate beats 45% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range 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 @Cornell post?
Most posts go out around 12:00 UTC, and Tuesday is its busiest day, at roughly 1.33 posts per day across the measured window.
