Ad Budget Allocator

Enter CPC + conversion rate per channel. We split the budget toward channels with the best conversions-per-dollar, using a sqrt-weighted model so allocations aren’t winner-take-all.

Model caveats: assumes linear conversion rate (no saturation), independent channels (no halo effect), and stable auctions. Treat as a starting point, then rebalance monthly on actual blended CPA/ROAS.
