Short Video: Reels, TikTok, ShortsLesson 1 of 5

What the algorithm actually “likes”

The algorithm isn’t a fan — it’s a counter

The algorithm doesn’t “like” you personally. It maximizes the odds that the next viewer won’t swipe and will do something.

It maximises the odds the next viewer doesn’t swipe away — and actually does something.

Signals that beat the myths

By priority
  1. 1Retention — how far they watched, where they dropped
  2. 2Rewatches
  3. 3Saves / shares / comments (not likes alone)
  4. 4Watching the key early seconds
  5. 5How similar the video is to what already worked for that person

What usually isn’t a cheat code

  • A secret hashtag
  • Posting “only at 6:03 p.m.”
  • The same sound as a millionaire account, with no meaning of your own
  • Buying views

Platform differences (very rough)

TikTok
from zero

Often easier to break through from zero

Reels
living profile

Leans harder on an already-alive profile + recommendations

Shorts
retention

Its own ecosystem; retention and clickability matter

The main signal

Takeaway: make a video people finish. Everything else is secondary.
