Where is this campaign losing money, and what would the fix bring?

One synthetic search campaign, last week: the report says which share of its eligible auctions it showed in, which share the budget kept it out of, and which share it was outbid in. Below that, a replay of last week’s auctions (the kind of estimate a bid or budget simulator makes) projects what a different bid or budget would have brought, and beside it is what next week’s auctions actually hold, in a world you choose. Move the bid and the budget, switch the world, and watch where the projection is honest and where it carries last week into a week that no longer exists. Synthetic data throughout.

Self-check: running…
