The X (Twitter) algorithm in 2026: what decides your reach?

What ranks the feed?

X's "For You" feed isn't chronological — an estimated engagement probability is calculated for each tweet and it's ranked accordingly. The core signals the model looks at: the replies/retweets/likes a tweet gets in its first minutes, time spent on the content, and especially replies. A reply weighs far more than a like because it's a genuine conversation signal.

• +The first 30 minutes are critical: early engagement determines whether the tweet is shown to a wider audience.
• +Reply > retweet > like: that's the weighting order. Content that pushes people to respond wins.
• +Time spent on the profile and opening/reading the tweet are positive signals too.

Penalized patterns

The algorithm penalizes some patterns by lowering reach. Most of these are in the "engagement bait" class:

• +"RT this", "like and follow", "👇 thread" and other overt engagement begging.
• +Many hashtags per tweet (1–2 is enough; 3+ is a spam signal).
• +External links: X wants you to stay on its platform, so a tweet with a link is somewhat suppressed — putting the link in the first reply is a common workaround.

How to write in practice

• +The first line is the hook: open with a specific claim, number, or tension — avoid generic sentences that stick to every day like "AI is everywhere."
• +Invite a reply, but not with a tacked-on generic question — create a genuine difference of opinion that arises from the content.
• +One clear idea: instead of cramming three ideas into 280 characters, say one idea sharply.
