Your first line is the whole post
On X, your first line decides whether anyone reads the second, so write it before anything else.
Picture your post in someone’s feed: a thumb moving fast, your words sliding past between a meme and a hot take. Nobody reads your third sentence if the first one didn’t make them stop. That’s not cynicism. It’s how you scroll too.
X’s open-sourced feed code says as much. Its ranking model tries to predict whether a viewer will dwell on a post, and it lists “not dwelled” among its negative signals, right next to mutes, blocks and reports. In an October 2026 update, X said its retrieval model is now also trained to surface posts people read all the way through. The code changes often, so don’t treat it as a formula. But the direction is clear: the system is built around whether people actually stop and read.
So write the first line before the rest. Lead with the result, the surprise or the specific number, then explain. Cut warm-ups like “So I’ve been thinking” and “Quick update.” If your first line only makes sense after reading the rest, flip the post upside down.
The example
- Instead of
- “So I’ve been thinking a lot about pricing lately and wanted to share a few thoughts on what we learned.”
- Try
- “I raised prices 40% and lost 2 of 180 customers. Here’s the exact email I sent.”
Before you flush
Rewrite the first line of your last three posts so each could stand alone as the entire post. Use the best version on your next post.
