There's a reason your "best" video and your "most viral" video are never the same.
Creators optimize for one metric. Usually views. Sometimes engagement. Rarely saves. Almost never shares specifically.
But these three signals are driven by completely different emotions. The content people save for later is not the content they send to friends, which is not the content the algorithm pushes to strangers.
We measured all three across 1,800+ videos. The leaderboards barely overlap.
Three metrics, three different winners
REACH: Views per follower by emotion
SAVES: Save rate by emotion (saves ÷ views)
SHARES: Share rate by emotion (shares ÷ views)
Look at those three charts. Different winners in each one.
The pattern
Reach (views per follower)
Winners: Outrage, Humor
Why: These emotions trigger comments and rewatches. The algorithm reads that as "push this further." Outrage makes people argue. Humor makes people replay. Both generate the signal the algorithm needs to distribute.
Saves (save rate)
Winners: Desire, Aspiration, Trust
Why: People save content they want to come back to. A recipe, a workout plan, a money tip, a tool recommendation. These aren't viral. They're useful. People bookmark them for later because the value isn't in the reaction, it's in the information.
Shares (share rate)
Winners: Fear, Outrage, Humor, Anger
Why: Sharing is an outward action. You send a video to someone because you need them to see it. "Look at this." "Can you believe this?" "This is so you." That requires an emotion strong enough to make you pull up someone else's name and hit send.
Why this matters
Most creators treat all engagement as the same thing. It's not.
If you want reach (the algorithm pushing your content to new people): lead with outrage or humor. These videos won't get saved much, but they'll get pushed to non-followers.
If you want saves (bookmarks, which signal long-term value to the algorithm): make desire and aspiration content. "Here's how to..." or "Here's the result of..." These are the videos people come back to.
If you want shares (people sending your video to friends): trigger fear, outrage, or humor. Shares are the most powerful distribution mechanism because they come with a personal endorsement.
The best content strategy rotates between all three. One outrage/humor video for reach. One desire/trust video for saves. One fear/surprise video for shares. Each one feeds a different part of the algorithm.
The biggest surprise in the data
Desire is the second most-used emotion (308 videos) but it ranks 9th for reach. Creators pile into desire content ("showing the result," "the lifestyle," "what I bought") because it feels like good content. It is good content. For saves.
But desire content barely breaks out of the follower base. Median reach ratio of 0.059 means a typical desire video reaches about 6% of the follower count. Compare that to outrage at 0.186 (19% reach) and the gap is obvious.
You need desire content in your mix. But it shouldn't be the only thing you post. It'll build your save library while your outrage/humor content does the actual growth work.
The complete leaderboard
| Emotion | Reach Rank | Save Rank | Share Rank |
|---|---|---|---|
| Outrage | 1st | 10th | 2nd |
| Humor | 2nd | 9th | 3rd |
| Curiosity | 3rd | 6th | 7th |
| Fear | 8th | 4th | 1st |
| Desire | 7th | 1st | 6th |
| Aspiration | 10th | 2nd | 8th |
| Trust | 6th | 3rd | 5th |
| Inspiration | 12th | 8th | 10th |
Outrage ranks 1st for reach but 10th for saves. Desire ranks 1st for saves but 7th for reach. Fear ranks 1st for shares but 8th for reach.
No emotion wins all three. That's the entire point.
The rotation strategy
Post 2-3 outrage or humor videos per week for reach. These are your growth drivers.
Post 1-2 desire, aspiration, or trust videos per week for saves. These are your retention drivers.
Post 1 fear or surprise video per week for shares. These are your word-of-mouth drivers.
Don't lead with inspiration. It ranks bottom 3 in all three metrics.
Track saves and shares separately from views. They tell you different things about what's working.
Reach gets you found. Saves get you remembered. Shares get you recommended. You need all three.
