X (Twitter)
How the X (Twitter) algorithm works
X (Twitter) rewards posts that get replies fast. Threads beat single posts. Skip URLs in the body. Keep hashtags to 0-1.

Where these numbers come from. This profile was built from the sources listed on this page, which include statements the platform made publicly.
- Published source codeThe 2024 X algorithm release, which set out the ranking weights and the reach cost of a link in the body
- Third-party studyHootsuite 2025 engagement study
We never present an estimate as something a platform announced. Where we are the source, this page says so.
How the feed is assembled
The signals X (Twitter) weighs when it decides who sees a post, strongest first. Weights are shown against a like, which is the unit everybody has an intuition for.
- Shares and reposts5x a like
- Comments3x a like
- Saves1.5x a like
- Likes1x a like
The first-hour cliff
The single most actionable fact on most networks, and the one almost nobody explains concretely.

Signals that matter most in that window
If a X (Twitter) post has not reached 40% of your own median engagement by minute 30, it rarely recovers. That is why the window matters more than the day: a post published into a dead hour has already lost before anybody decides whether it was any good.
Best posting windows
Every hour of the week, as a multiple of a median X (Twitter) hour. On Pro and above we rank your posting slots against this curve and your own posting history; on Free and Starter the queue uses our regional best-time table without the personalised ranking.

Where we place your link
Content Drifter publishes the post without the link and posts the link as the first comment, rewriting the body so it still reads as a whole. Most schedulers attach a first comment and leave the URL in the body, which keeps the full penalty. How the first comment works.
Posting cadence and cooldowns
Posting more is not posting better. These are the ceilings the queue applies when it assigns slots, counted against your own calendar rather than UTC.

Format mechanics
What X (Twitter) accepts, and which formats carry a reach advantage over a plain post.
Reach by format
- Thread+70%
- Video+50%
- Poll+30%
- Single image+20%
- Standard post0%
Hard limits
- Ideal length
- 71 to 100 characters
- Platform limit (enforced)
- 280 characters
- Hashtags for reach
- 1 ideal, 2 before it costs you, end of post
- Hashtags allowed
- 5 by the platform
- Images per post
- 4
- Video
- up to 140s, 512MB
- Image formats
- jpeg, png, gif, webp
More than 2 hashtags reduces reach measurably (2024 leak).
How Content Drifter applies this to your X (Twitter) posts
Each row pairs a number from this page with the thing the product does about it. This is the same record, not a marketing restatement of it.
A link in the body costs about 40% of X (Twitter) reach.
We publish the post without the link and post the link as the first comment, rewriting the body so it still reads as a whole.
Link in the first commentX (Twitter) engagement peaks around 08:00 to 10:00 UTC on Monday, roughly 2.52x a median hour.
Add a post to the queue without picking a time and it takes the next open peak slot in your timezone, skipping slots already full. On Pro and above those slots are ranked against this curve and your own posting history.
Gold Slot schedulingThread outperforms a plain post by about 70% on X (Twitter).
Generation targets the formats that carry a lift on the network you are posting to, rather than producing one body and cross-posting it everywhere.
Per-platform publishingX (Twitter) rewards engagement in the first 30 minutes, and a post that starts flat rarely recovers.
On Agency plans with the boost engine switched on, we check the post at the 30 minute mark against your own median, so a stall is something you find out about while it can still be acted on.
The algorithm-aware enginePosting more than 8 times a day, or inside 1 hour of your last post, works against you on X (Twitter).
The queue honours that spacing when it assigns slots, counting posts you already published as well as ones you have queued, so a bulk import or a busy week cannot bunch your posts together.
The queueX (Twitter) posts land best between 71 and 100 characters, against a platform limit of 280.
The pre-publish check reads the post against these rules and tells you which one it breaks, rather than handing you a score.

Recent X (Twitter) algorithm changes
Changes we have recorded and reviewed. Nothing appears here automatically.
We have not published a recorded change for X (Twitter) since our last check. Our canary compares engagement across our whole user base against a 28-day baseline every day, and a shift is reviewed by a person before it appears here, because saying in public that X (Twitter) changed something is a claim about somebody else’s product.
X (Twitter) algorithm questions
What is the best time to post on X (Twitter)?
Our strongest window is 08:00 to 10:00 UTC on Monday, which runs about 2.52x a median hour, followed by 09:00 UTC on Tuesday. Those are UTC. Content Drifter converts them to your timezone and schedules into them for you, so the number you are reading is the one it acts on.
What does the X (Twitter) algorithm reward most?
shares and reposts carry the most weight, about 5x a like in our model, then comments at 3x. X (Twitter) rewards posts that get replies fast. Threads beat single posts. Skip URLs in the body. Keep hashtags to 0-1.
Do links hurt reach on X (Twitter)?
Yes. We model a body link as costing about 40% of reach, and we place links in the first comment instead. Content Drifter does that automatically and rewrites the body so the post still reads properly without the URL in it.
How often should I post on X (Twitter)?
We cap at 8 posts a day and 35 a week, with at least 1 hour between posts. The queue applies these when it assigns slots, using your own calendar day rather than UTC, and counts what you have already published as well as what is queued.
Which post format performs best on X (Twitter)?
Thread carries the largest lift in our model, roughly 70% above a plain post. Generation targets the format that wins on the network you are publishing to.
How long should a X (Twitter) post be?
Between 71 and 100 characters. X (Twitter) allows up to 280, which is what we stop you at. Hashtags work best at 1 and start costing you reach above 2, well below the 5 the platform permits.
