Question

Estimate Monthly Revenue for a New Shopping Tab (Organic Only)

Context

You are evaluating the potential monthly revenue impact of launching a new Shopping tab in a social photo app. Only organic surfaces are in scope (organic posts and in-app search). Exclude ads and any paid placements.

You have access to the following data from current organic experiences:

Organic impression counts (e.g., product tiles in feed, creator posts with product tags, organic search results)
Product detail page (PDP) views
Add-to-carts (ATC)
Purchases (in-app)
Average order value (AOV)

Assume purchases are on-platform and can be linked to prior organic exposures.

Task

Using the available data, estimate monthly potential revenue if the Shopping tab is launched to 100% of users. Provide:

(a) A clearly specified conversion funnel and algebraic formula for revenue.

(b) How you would obtain unbiased CTR/PDP rates from current organic entry points (given position/selection biases).

(c) How you would adjust for cannibalization of existing organic purchases.

(d) How you would scale from experiment traffic to the full population while accounting for heterogeneity.

(e) A sensitivity analysis on the key assumptions and parameters.
