Big updates have come to the Budget estimate tool. For starters, there are new options available: you can now get separate estimates for mobile impressions, forecast your weekly expenditures, and choose the currency used in calculations.
Additionally, the implementation of a new algorithm has further increased the tool's accuracy. Previously, the system focused on the specific conditions "here and now" and general statistics when making calculations. Now, it uses statistics for the selected period. It takes real data from the equivalent season and considers the positions, bids, number of impressions, CPC and click count for your chosen keyword, at different times of days and different days of the week. Along with prices, it also calculates potential reach in different positions.
