## A post with an active reply thread reaches more non-followers than one with plenty of likes but no conversation.
The key window is the first 30 to 60 minutes. If your post earns replies, reposts, and profile visits in that window, X treats it as worth showing and pushes it further.
### Reply velocity matters most.
- Block 30 minutes after you post.
- Ask a follow-up instead of only marking the reply.
- Even accounts under 500 followers can pick up reach by seeding a conversation early.

## The first line decides whether anyone reads the rest.
Posts around 110 characters tend to earn more engagement. Stick to one or two relevant hashtags per post.
### Four hook types consistently beat generic openers.
- A surprising stat.
- A bold opinion.
- A before and after.
