Engagement
A typical post picks up 30 interactions against 217K followers, an engagement rate of 0.014%. Measured over 96 original posts, its engagement rate beats 25% of 15,823 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 8.1K times each, and 0.369% of those impressions turn into an interaction. That is about 3.74% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.4 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 20:00 UTC, and Thursday is the busiest day of the week. Of the 96 posts sampled, 56% carry an image or video. The account's strongest tracked post pulled 2.5K interactions, about 85x its own typical post.

Compared with accounts its own size
Antonio Costa's engagement rate beats 25% of the tracked X accounts closest to it in follower count (15,823 accounts, accounts of similar size (decile 8 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 21% 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 0.014%, Antonio Costa sits above the 10th percentile of the 160,730 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.022%.

Posting timing
This account posts most often around 20:00 UTC, and Thursday 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 | 56% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 3% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | -3% | -3% to -2% | 54K |
- 56% 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.
- 3% 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 133 characters, which falls in the 80 - 180 characters band. Across the catalog, posts of 80 to 180 characters run 3% below 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.

I have filed a 13D on SSM on behalf of Alpine Fox Capital LLC and Alpine Fox LP. Via my entities, I now control 21.5% of the shares outstanding. Chris Kelly's new company Sports One is intriguing and I am bullish on tokenized sports equity (NFL, NBA, MLB, NHL). https://t.co/PXbrWwN0uy

Dearest followers, I would like once again to remind everyone, that I don't have any TELEGRAM, Facebook, Threads or Instagram account. Scam artists are using my Twitter profile photo on a daily basis to create fake profiles and then trying to trick people into promoting its scam products. Please be aware of these schemes going around. I've been verified on Twitter for over 4 months. I don't send private Twitter messages promoting services nor ask you for money. Thank you very much to all of you that everyday report these scam artists bc they block me first to avoid being found. I really appreciate your help.

Good morning everyone !! The oversold condition of $NIO shares is getting so ridiculous that we’ll soon have a session that rallies 15–20% in a single day. A sharp bounce is more than likely. I’m all in !! Perfect chart setup for bargain hunters !!

- What is Antonio Costa's engagement rate on X?
- Antonio Costa (@ACInvestorBlog) has an engagement rate of 0.014%, based on the median interactions across 96 original posts from the last 30 days against 217,122 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.014%, Antonio Costa sits above the 10th percentile of the 160,730 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 @ACInvestorBlog have real engagement?
- Its engagement rate beats 25% of the tracked X accounts closest to it in follower count (15,823 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 @ACInvestorBlog post?
- Most posts go out around 20:00 UTC, and Thursday is its busiest day, at roughly 3.43 posts per day across the measured window.
