What each platform says it uses
| Platform | Main signals it names |
|---|---|
| Your activity, the post's popularity, your history with the poster | |
| TikTok | Your interactions, video details like captions and sounds, device settings |
| YouTube | Viewing behavior, likes, dislikes, satisfaction surveys |
| Predictions of how likely you are to engage |
What they have in common
- They rank each post for each person, not for everyone.
- Early reactions shape how far a post travels.
- Watching, sharing and saving count more than a quick scroll.
- Platforms show low-quality or recycled content less.
TikTok states that follower count does not directly decide For You reach. Instagram says it shows low-resolution, watermarked and reposted reels less.
How to adapt when things change
- WatchTrack reach and watch time for a few weeks.
- CompareSee which formats gained or lost.
- TestTry small changes to hooks and length.
- KeepHold on to what still brings messages.
Avoid chasing every rumor about secret rules. Platforms publish what they value, and it rarely changes overnight.
Good example. A gym notices Reels reach dropped after an update. It tests shorter hooks and member stories, and reach recovers within a month.
Bad example. A gym hears that posting at 7:13 a.m. beats the algorithm. It changes nothing else, and reach keeps falling.
