<b>Save rate predicts 7-day reach with r=0.71; like rate predicts almost nothing</b>

<b>Save rate predicts 7-day reach with r=0.71; like rate predicts almost nothing</b>
We ran correlations between each engagement signal and downstream reach. The hierarchy is clear.

— Saves → 7-day reach: r=0.71 (strongest)
— Shares/sends: r=0.64
— Comments: r=0.38
— Likes: r=0.11 (statistically near-noise)

Likes are a vanity signal the algorithm has largely discounted. Optimize content for the save and the send: reference-value posts (lists, frameworks, how-tos) and tag-a-friend hooks beat aesthetic likeable posts on distribution.
