Short answer
Put the point in the first line, write the way you talk, cut every word that doesn't earn its place, use one idea per post, and add an image or a specific detail people can react to.
Key takeaways
- The first 60 to 80 characters decide whether people keep reading.
- Specific details (numbers, names, places) beat general claims.
- Threads for steps and stories, single posts for opinions and news.
Most posts on X are skimmed in under two seconds. Good writing on X isn't fancy; it's fast to understand. These are the rules we come back to when drafting.
What makes a post readable in the timeline?
A strong first line, short sentences, and white space.
- Lead with the point. The first line shows in full in every timeline; make it carry the post. "We cut our signup form from 7 fields to 2" beats "Some thoughts on onboarding".
- Write like you talk. If you wouldn't say it out loud, rewrite it.
- Use line breaks. Two or three short paragraphs are easier to read than a block.
- One idea per post. Two ideas compete; save the second for another post.
How do I make people care?
Be specific, show something, and give them a reason to reply.
- Use concrete details. Numbers, names, places, prices. "Our café used 40% less milk after switching to 8 oz cups" earns attention that "We cut waste" doesn't.
- Add an image when it carries information: a chart, a screenshot, a before-and-after. Decorative stock photos add nothing.
- Ask a real question when you want replies, one you'd want to read answers to.
- Have an opinion. Hedged posts get scrolled past.
When should I thread or write a long post?
Thread for steps, stories and lists; long post (Premium) for a single argument; single post for everything else.
- Number threads (1/6) so readers know the length, and make post 1 work on its own. Our character counter splits long text at sentence breaks.
- Long posts get cut at about 280 characters with Show more. The opening has to earn the click.
What should I avoid?
Filler openings, hashtag piles and begging for engagement.
- Skip "Thread 🧵👇" with no content. Say what the thread is about.
- Don't end with "Like and repost!" It rarely helps and reads as needy. End with your strongest line, or a question.
Before you post, read it once on your phone. If you wouldn't stop scrolling for it, edit. X Premium users can edit within an hour; everyone else can't, so the read-through matters. Mock up important posts first in the generator to see how they look in the feed.
Questions people ask
What's the ideal length for an X post?
There isn't one magic number. Many high-performing posts are under 150 characters, but a well-written 270-character post beats a vague short one. Long posts suit Premium users writing essays.
Should I post links in the main post?
X has been observed to favor posts that keep people on the platform. Many writers put the key point in the post and the link in a reply. Test both for your account.
How often should I post?
Consistency beats volume. A few good posts a day, or even a week, outperform a stream of filler.
