Instagram Reels Ad Load Decision: Testing One Ad per Five Organic Videos

You are a product manager at Meta working on Instagram Reels. The team proposes showing an "Ad Reel", a sponsored video in the Reels stream, after every fifth Reel a person watches. Explain how you would decide whether Instagram can introduce this. ```hint Weigh now against later Extra ad slots can raise revenue right away while lowering engagement more slowly. Decide which effects on viewers, creators and advertisers you would measure, and over what period, before you make the call. ``` ### Clarifying Questions - Does Reels already show ads at a lower or variable frequency, or would this be the first ad placement in Reels? - Would the slot be fixed at every fifth Reel for everyone, or could the frequency vary by user, session or market? - Is the main aim more revenue, or more video inventory to meet advertiser demand? - Can viewers swipe past an Ad Reel immediately, as they can with an organic Reel? ### What a Strong Answer Covers - The goal behind the proposal and the trade-off being decided: ad revenue and advertiser value against the experience of viewers and creators. - Business, counter and guardrail metrics for each stakeholder, fixed before any test runs. - An experiment design that captures long-term effects on usage and ad attention, including the randomization unit, duration and holdouts. - Segment-level reading of results (new versus established users, heavy versus light viewers, markets) and how ad prices may change at full scale. - A clear decision rule, a rollout plan, and alternatives to a fixed every-fifth slot. ### Follow-up Questions - The test shows Instagram ad revenue up but fewer daily Reels sessions among new users. Do you launch? - How would you check whether the extra inventory lowers ad prices or advertiser results once it is live for everyone? - Would you prefer a model that chooses when to show each ad over a fixed rule? What new risks does that bring?
