Open-source X algorithm · decoded

Your reach dies in the first 30 minutes.
We tell you why.

Replying to your own repliers is weighted 150× more than a like in X's ranking. Most creators never do it. ReachBleed catches every signal you're missing — and emails you the one fix that recovers the most.

The problem

You're posting into the void.

X's algorithm is not random. Every post is judged in its first 30 minutes — a tight scoring window the vast majority of creators don't even know exists. If your velocity signal is dead, your post never escapes to non-followers. You don't get a second chance.

How it works

Three steps. One email. No dashboards.

ReachBleed runs in the background. You post. We watch. Every week you get the one thing to fix — ranked by impact.

  1. Connect your X account

    One click, read-only OAuth. We never post, never store your password. You're connected in under 20 seconds.

  2. We watch every post

    ReachBleed monitors the first 30 minutes of every post you publish — tracking velocity, engagement signals, link penalties, and reply coverage.

  3. You get the weekly fix

    Every week, one email: your Wasted Reach Index, your biggest leak, and the precise action that recovers the most reach. Nothing else.

The metric that matters

The Wasted Reach Index.
Every post has one.

X's algorithm scores each post against a theoretical maximum reach — how far it could have spread given your follower graph. The Wasted Reach Index is the gap: the percentage of that potential your post never captured.

A WRI of 0% means you extracted every signal available. A WRI of 70% — which is average — means seven tenths of your potential audience never saw your post.

We also track your Growth Deficit — the cumulative reach you've left unclaimed across all your posts this week. It compounds. Most creators don't realise how large the number is until they see it.

This week's fix

Reply to the 12 people who commented within the first 2 hours. That's 12 author-reply signals you're sitting on — at 150× weight each.

82% of your recoverable reach this week comes from this one action.

Signal detection

Every leak, caught.

The X ranking algorithm has a dozen levers most creators never touch. ReachBleed watches all of them — every post, every week.

  • Missed author replies

    Replying to your own repliers is the single highest-leverage signal in X's ranking — weighted ~150× a like. We track every reply you miss in the critical window.

    Highest impact
  • Dead first-30-minute velocity

    If your post doesn't hit the engagement threshold in its first half hour, X's algorithm caps its distribution to your follower graph and never promotes it further.

    High impact
  • External link suppression

    Posts with links to off-platform URLs receive a documented out-of-network penalty. We flag these and suggest threading strategies that preserve reach.

    Moderate impact
  • Low quote/repost amplification

    Secondary amplification signals extend your reach to the graphs of your amplifiers. Posts that miss their quote/repost window lose a compounding growth lever.

    Moderate impact
  • Off-peak scheduling

    Your follower graph has a peak attention window. We identify it from your own engagement history — not generic "best time to post" advice.

    Recoverable
  • Weak thread structure

    Thread post #1 sets the ceiling for the whole thread. A soft opener — even with strong follow-ups — limits total impressions across every post in the chain.
