Question

Designing an "Effective Read" Metric for a Newsfeed

Scenario

You are tasked with defining and measuring an "effective read" for posts in a social newsfeed that includes text, images, videos, and link posts. The metric will be used both to report user value and as a potential label/feature for ranking.

Question

How would you define and measure an "effective read" on a newsfeed? Specify:

The operational definition and component signals (e.g., time-on-screen, viewport coverage, interactions).
Concrete thresholds or normalization rules across content types.
The core metrics you would report (e.g., rates, distributions, guardrails).
Validation and experimentation you would run to ensure the definition reflects true user value and is robust to gaming.

Consider duration, screen coverage, engagement follow-ups, baseline rates, and A/B tests to prove business impact.
