EQI: The Engagement Quality Index

The Missing Middle™ needed a number.

EQI, the Engagement Quality Index™, is that number.

EQI is Promobiley's proprietary composite metric for engagement quality. It synthesizes completion behavior, interaction depth, participation intensity, progression quality, sustained engagement, behavioral momentum, and consideration behavior into a single comparable signal.

Hub and spoke model where hub is Engagement Quality and spokes are signals: completion behavior, interaction depth, participation intensity, progression quality, sustained engagement, behavioral momentum, and consideration behavior.

Two campaigns can share a click-through rate and nothing else.

EQI is what tells them apart.

It lets an organization compare engagement quality across campaigns, audiences, channels, interaction formats, and creative environments.
Not just whether engagement happened, but how much it mattered.

Observed, not modeled.

EQI is generated from behavior captured inside environments Promobiley plans and builds.

It is not survey-based, self-reported, or modeled from probability. That's why it's defensible under scrutiny: the conditions producing it are standardized, so the score means the same thing campaign to campaign.

Not a vanity metric. Not an engagement rate.

Not a replacement for conversion metrics.

EQI is a diagnostic intelligence layer that quantifies the quality of audience engagement between exposure and conversion.

It doesn't replace downstream business metrics. It explains them.

Engagement quality is not soft brand activity.

It is observable behavioral intelligence that explains downstream outcomes.
