Method
ARPDE is the whole score. Keep it boring.
When installs exist
ARPDE = revenue_usd / installs.
When installs are missing
We fall back to revenue per 1,000 impressions. That path is Assumed. Prefer install-attributed rows.
Spread
Top ARPDE minus bottom ARPDE. Large spread means you are leaving money on a weak slot.
Assumed realloc hint
Move 20% of the bottom slot's impressions to the top slot. Hold conversion rates constant. Report Assumed revenue lift. It is a planning number for the live-ops note, not a guarantee.
What this is not
Not a bid strategy for Unity Ads Source Level Bidding. Not a mediation optimizer. Owned inventory only.
