How rare is a 10x post?
About 1 in 30. A 10x post is a genuine outlier, not a fluke.
Posteriks finds posts that beat their own account baseline in your niche and helps you build your own version — not a copy. Check your own post free →
The baseline multiple — a post's engagement divided by your page's median — turns "it did well" into a number you can rank. Here's how rare each level is across our study of 19,624 posts:
| Result | Share of posts | Roughly |
|---|---|---|
| 5× baseline | 7.5% | 1 in 13 |
| 10× baseline | 3.4% | 1 in 30 |
| 20× baseline | 1.5% | 1 in 67 |
| 50× baseline | 0.5% | 1 in 200 |
So a 10x post isn't luck-of-the-draw noise — it cleared a bar only about 3% of posts reach. Don't let it disappear: figure out why it broke out and rebuild the pattern into new posts.

FAQ
Is a 10x post just luck?
Only about 3.4% of posts reach 10x their baseline, so it's a real outlier, not noise. It's worth studying why it worked and rebuilding the pattern.
What's the difference between 5x and 10x?
5x happens to roughly 1 in 13 posts; 10x to about 1 in 30. Each step up the multiple is sharply rarer.
