"High engagement rate means high earnings" is a measurement artifact

Engagement rate is sold as a monetization proxy. Its relationship to revenue is weaker and more perverse than assumed.

Context. Engagement rate is typically interactions divided by followers — a ratio whose denominator shrinks the metric as accounts grow.

Findings. Because the ratio is mechanically inflated at small account sizes, cross-creator engagement comparisons are mostly noise. Studies linking engagement to brand-deal outcomes through 2025 find weak correlation with conversion once audience size and niche are controlled. Brands increasingly price off cost-per-acquisition and view-through, where high "engagement" (likes, vanity comments) shows near-zero predictive value for sales.

Caveats. Engagement does predict some things — algorithmic distribution, saves, and shares carry real signal. The failure is treating one composite ratio as a revenue indicator. Self-reported brand outcome data is also thin and confidential.

Implication. Optimizing engagement rate can mean optimizing for small audiences and vanity interactions. Saves, shares, and downstream conversion matter for revenue; the headline ratio largely doesn't.

What we still don't know: no public dataset connects creator engagement metrics to verified per-campaign sales.
