Script 813: SBA Campaign Pacing with Rec. Budget and Current Budget

Purpose

The Python script optimizes budget allocation for marketing campaigns to minimize lost impression share due to budget constraints.

To Elaborate

The script addresses the challenge of efficiently allocating marketing budgets across various campaigns to minimize lost impression share due to budget limitations. It considers several factors, including the remaining budget for each Salesforce Item ID Budget Group, the number of weekdays left in the month, historical spending patterns, and the potential for future spending. The script also ensures that only active campaigns with recent spending are considered for budget allocation. It calculates the full potential spend for each campaign, caps it at twice the historical spend, and allocates the remaining budget based on this potential. The script also calculates the recommended daily budget for each campaign, ensuring it meets a minimum threshold, and adjusts the budget pacing to align with the overall strategy. This process helps in maintaining an optimal budget distribution across campaigns, ensuring efficient use of resources and maximizing campaign performance.

Walking Through the Code

  1. Initialization and Setup
    • The script begins by setting a configurable parameter, MINIMUM_DAILY_BUDGET, which users can adjust to set the minimum daily budget for campaigns.
    • It checks if the script is running on a server or locally, loading data from a pickle file if running locally.
  2. Data Preparation
    • The script imports necessary libraries and sets up the input data frame (inputDf) from the loaded data.
    • It converts certain columns to appropriate data types and sets the index for grouping operations.
  3. Spend Calculation
    • The script calculates the full potential spend for each campaign by adjusting historical spend based on lost impression share due to budget constraints.
    • It aggregates data to calculate month-to-date (MTD) spend and prepares for budget allocation.
  4. Campaign Filtering
    • Campaigns that are inactive, have no recent spend, or have expired program dates are excluded from budget allocation.
  5. Budget Allocation
    • The script calculates the budget allocation ratio, capping full potential spend at twice the historical spend.
    • It computes the remaining budget for each SBA Strategy budget group and allocates it to campaigns based on the calculated ratio.
  6. Daily Budget Calculation
    • The script calculates the recommended daily budget by dividing the allocated budget by the number of remaining weekdays in the month.
    • It ensures that the recommended daily budget meets the minimum daily budget requirement.
  7. Output Preparation
    • The script identifies campaigns with changes in budget recommendations and prepares the output data frame with updated budget values.
    • It outputs the results, showing only the campaigns with changes, ensuring efficient budget management.
