X's recommendation system updated in May 2026. If your impressions dropped after that, you are not imagining it.
The change was not a bug or a penalty aimed at specific accounts. It was a deliberate shift in what the algorithm rewards. The accounts that adapted are growing. The ones that did not are posting into silence.
Before the update, volume was a workable strategy. Post enough, reply enough, and the numbers would move in roughly the right direction. The algorithm was less discriminating about engagement quality.
That changed. The May 2026 update introduced heavier weighting on what X calls "attention quality." The system now distinguishes between an impression that generated dwell time, profile clicks, and follow-through versus one that got a quick scroll past. Low-attention impressions still count toward your total, but they do not trigger algorithmic expansion the way high-attention ones do.
For accounts that were growing on volume, the floor dropped. For accounts generating deep engagement, not much changed.
The practical effect is that generic replies are getting buried more than before. Not removed. Not flagged. Just buried.
A reply that reads like a template, any template, produces low dwell time. Readers see it and scroll. The algorithm reads that as a low signal and deprioritizes the reply within the thread. That same reply used to float. Now it sinks.
Writing better replies is not just about standing out to readers. It is about generating the behavioral signals the algorithm now requires to push your content further.
The harder thing to absorb is that great writing still does not save a badly placed reply.
The update also tightened the expansion window. X is now weighting reply velocity in the first burst of a post's lifecycle more heavily than before. A reply placed in the first 15 minutes after a post goes live generates more algorithmic weight than it did before May. A reply placed two hours later generates less.
Timing was always important. After this update, it is the primary variable. Good writing in the wrong thread still goes nowhere. Good writing in the right thread, posted early, now performs better than it ever did before.
The accounts winning after the May 2026 update are doing two things: writing replies that add specific, non-obvious value, and placing them inside the first 15 to 30 minutes of a post's lifecycle. Neither of those things requires more time on X. They require better targeting.
ReplyHunter shows you which posts are still in their expansion window so your replies land when the algorithm is actively pushing the thread, not after it has moved on.

What changed in X's algorithm in May 2026?
X's May 2026 update shifted the recommendation system toward "attention quality", a measure that weighs dwell time, profile clicks, and follow-through more heavily than raw like and repost counts. The algorithm now distinguishes between impressions that generated meaningful engagement and ones that got a quick scroll past. High-volume strategies that relied on quantity over quality saw a drop in reach. Accounts generating deep engagement per reply were largely unaffected.
Why are my X impressions dropping after the May 2026 update?
If your replies tend toward generic agreement or templated structure, the update likely reduced their algorithmic reach. The system now buries low-attention replies more aggressively than before, meaning the same reply that used to float in a thread now sinks. The fix is not more replies, it is replies with a specific angle, non-obvious insight, and a genuine question that keeps conversation going, posted early in a thread's lifecycle.
What is "attention quality" on X?
Attention quality is X's internal metric for how meaningfully people engage with content after they see it. A high-attention impression is one where the reader paused, read further, clicked a profile, or responded. A low-attention impression is a quick scroll-past. The May 2026 update increased the weight of attention quality in the algorithm's expansion decisions, meaning content that generates dwell time gets pushed further than content that generates the same raw view count without behavioral follow-through.
How do you write replies that the X algorithm rewards in 2026?
Focus on one specific angle of the post rather than addressing everything. Add something non-obvious, a counterpoint, a specific data point, a reframe. End with a genuine question that invites a response from the original poster. Keep it short enough to read on a phone mid-scroll. The goal is to produce a reply that makes the reader pause, re-read, or click your profile, those behaviors are exactly what the updated algorithm rewards.
Does the X algorithm still favor early replies after the May 2026 update?
More than before, yes. The update increased the weight X places on reply velocity in the first burst of a post's expansion phase. A reply placed in the first 15 minutes after a post goes live now carries more algorithmic weight than the same reply placed two hours later. The combination of quality writing and early placement performs significantly better post-update than either factor alone did before it.
