Success factors
Why the top posts worked. Your best posts (top 25 all-time plus the top engagement decile) get auto-tagged with likely success factors; confirm the ones that fit and add any that were missed. Confirmed factors drive the “what works” correlation on Insights — AI suggestions never do until you confirm them.
