Estimate Instagram Stories Ad Revenue | Dataford Interview Questions

Company Context

Meta operates one of the largest global ads businesses, with Instagram as a core consumer surface and monetization engine. Instagram Stories is a high-frequency, full-screen format with broad adoption across creators, everyday users, and advertisers, but monetization must be balanced against user experience and creator engagement.

Problem

You are the PM for Instagram Stories monetization. Leadership wants a bottom-up estimate of annual ad revenue from Instagram Stories and a recommendation on what product levers to prioritize next. You do not have exact internal numbers, so you must build a reasonable estimate using explicit assumptions and show how product decisions affect revenue.

Assume Stories has strong global usage, ads appear between organic Stories, and revenue depends on a combination of inventory, fill rate, pricing, and engagement quality. Your estimate should distinguish between user value and advertiser value rather than treating Stories as pure ad supply.

Deliverables

Build a back-of-the-envelope model to estimate annual Instagram Stories ad revenue, clearly stating assumptions and formulas.
Identify the most important user segments and Jobs-to-be-Done that make Stories valuable enough to monetize.
Recommend 2-3 product or monetization levers Meta should prioritize to grow Stories revenue over the next 12 months.
Define success metrics and guardrails to ensure revenue growth does not degrade the Stories experience.
Explain the key trade-offs in increasing ad load, targeting quality, and creator/user retention.

Constraints

You cannot use exact internal Meta data; use directional assumptions and sanity checks.
Your recommendation should be realistic for a 12-month roadmap, not a multi-year platform rewrite.
Any proposed changes must preserve the fast, lightweight, immersive nature of Instagram Stories.
Assume increased monetization that materially hurts user retention or Story creation would be considered a failed outcome.
