After 9M views, she read X's open-source algo to crack its ranking
dunkhippo33 · x · 2026-10-14
Creator @0xJuliechen got 9M views in 3 months, then read X's open-source algorithm code after major changes:
- Weights: copy-link share 20; reply/quote/DM share 5; follow 4; repost 1; like 0.5. Likes barely move the score—write things people copy the link to, argue with, or send to friends.
- Timing: first 2 hours decide everything; posts drop out of For You after 48 hours.
- Mutual follows: replying to a mutual inside your own thread gets +15, matching a copy-link share.
- Misc: use edit instead of delete-and-repost; images aren't penalized but info-carrying ones (screenshots, real scenes) perform better.
