Lviv, Ukraine
We are developing a system (called “Bidder”) which recommends (or adjusts) Google Ads costs per click for specified campaigns using revenue forecasts, cost forecast and available capacity of time slots for commercial and residential HVAC, plumbing, electrical, and other field services.
The Bidder should compute Google Ads bid-values to maximize some target. The target function is synthetic profit based on the difference between forecasted totals which will be obtained in the future from customers and cost calculated as the number of forecasted clicks multiplied by the recommended cost per click (CPC). Totals are aligned to the Google Ads items clicked by customers.
