A typical post picks up 34 interactions against 201K followers, an engagement rate of 0.017%. Measured over 15 original posts, its engagement rate beats 30% 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 5.1K times each, and 0.672% of those impressions turn into an interaction. That is about 2.52% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.9 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 15:00 UTC, and Wednesday is the busiest day of the week. Of the 15 posts sampled, 7% are part of a thread and 73% link out. The account's strongest tracked post pulled 957 interactions, about 28x its own typical post.

Compared with accounts its own size

David Roberts's engagement rate beats 30% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 9 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 33% 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 0.017%, David Roberts sits above the 10th percentile of the 205,261 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 205,261 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 15:00 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.

Engagement by hour posted, UTCTwenty-four bars, one per UTC hour. Each bar shows how posts published in that hour compare with their own authors' median engagement. Bars above the centre line ran higher than the median, bars below ran lower. A marker flags Busiest hour: 15:00 UTC.

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 video0% of posts+111%+108% to +115%34K
Outbound link73% of posts-41%-42% to -40%32K
Typical length-no effect-2% to -1%42K
  • 0% 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.
  • 73% 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 253 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.

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.

    God, this is so, so good. It should make everyone in America's decadent media establishment -- and everyone on this deranged website, marinating in Musk's algorithm -- feel bad about themselves. But of course it won't. https://t.co/POpZE0HqOc

    Here's what I think about when I think back on 9/11. The attack happened on the watch of a Republican president who had been warned, repeatedly & explicitly, that an attack was coming. He dismissed those warnings.

    Politically speaking, the US clean energy industry is a pathetic, cringing weakling, practically begging to have sand kicked in its face. If you doubt, read this piece in @monthly. “We’re in the business of making friends, not making enemies.” 🤮 https://t.co/fpvcXLd5rS

    Today on Volts: an epic conversation with @JaneAFlegal. We talk industrial policy, what IRA got right & wrong, the role of philanthropy, data centers & the grid, permitting reform, & so much more. Jane is one of the sharpest analysts out there, could listen to her talk forever. https://t.co/MxPdaqulMQ

    Today on Volts: disinformation about clean energy is everywhere these days -- online, in local siting meetings, in regulatory dockets. The folks at GoodPower are fighting back with a rapid-response team, an army of local influencers, & new tools to identify bots & fakes. https://t.co/haHm23NSQi

    Today on Volts: Home batteries are useful, but not everyone can afford a Powerwall, or wants to deal with an electrician. A company called @PilaEnergy is selling small (1.6kWh) batteries that can plug into a normal wall outlet and back up appliances or pair with rooftop solar. I talk with the CEO. https://t.co/LdR6QlJXyK

    Today on Volts: in lithium-ion batteries, the cathode has been evolving for 30 years, but the anode has remained stubbornly graphite. Now silicon anodes, which promise 5X the energy density & charging speeds, are finally reaching commercial viability. I talk with a silicon-anode pioneer. https://t.co/pDMClZwFvm

    Today on Volts: Verrus wants to build data centers that use very little water, run quietly, & rely on giant batteries rather than diesel or natgas generators, which can make them grid assets that help reduce power prices. It hasn't overcome local opposition. I talk with the CEO. https://t.co/19UIiH0NRo

Reading these numbers

A typical post picks up 34 interactions against 201K followers, an engagement rate of 0.017%. Measured over 15 original posts, its engagement rate beats 30% 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 5.1K times each, and 0.672% of those impressions turn into an interaction. That is about 2.52% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.9 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 15:00 UTC, and Wednesday is the busiest day of the week. Of the 15 posts sampled, 7% are part of a thread and 73% link out. The account's strongest tracked post pulled 957 interactions, about 28x its own typical post.

What is David Roberts's engagement rate on X?
David Roberts (@drvolts) has an engagement rate of 0.017%, based on the median interactions across 15 original posts from the last 30 days against 200,755 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
Is that a good engagement rate?
At 0.017%, David Roberts sits above the 10th percentile of the 205,261 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 @drvolts have real engagement?
Its engagement rate beats 30% 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 @drvolts post?
Most posts go out around 15:00 UTC, and Wednesday is its busiest day, at roughly 0.9 posts per day across the measured window.
