Script 993: SBA Campaign Pacing Meta

Purpose

Python script that allocates budgets to campaigns based on various factors such as remaining budget, weekdays in the month, historical spend, and minimum daily budget.

To Elaborate

The Python script solves the problem of allocating budgets to campaigns in an efficient and optimized manner. It takes into account the remaining budget for each Salesforce Item ID Budget Group, the number of weekdays in the month, historical spend and spend potential, campaigns with spend in the lookback period, and the minimum daily budget. By considering these factors, the script ensures that budgets are allocated in a way that maximizes the impact and minimizes the lost impression share due to budget constraints.

Walking Through the Code

  1. The script starts by defining a configurable parameter for the minimum daily budget.
  2. It then checks if the code is running on a server or locally and initializes the necessary data sources accordingly.
  3. The script defines various column constants and imports the required libraries.
  4. It sets the outputDf same as the inputDf and sets up the client timezone.
  5. The script performs some data preprocessing tasks such as changing data types and coercing the Program End Date into a Date type.
  6. It groups the input data by the Salesforce Item ID Strategy and calculates the full-potential spend by adjusting the historical spend based on the lost impression share due to budget.
  7. The script removes date segmentation and calculates the MTD spend for each campaign.
  8. It excludes campaigns that are not active, have no spend in the lookback period, or have a program end date in the past.
  9. The script calculates the budget allocation ratio by capping the full-potential spend and comparing it to the total spend within the same Salesforce Item ID budget group.
  10. It calculates the remaining budget for each Salesforce Item ID budget group by subtracting the MTD spend from the SBA monthly budget.
  11. The script allocates the remaining budget to each campaign according to the allocation ratio.
  12. It calculates the next day’s daily budget by dividing the allocated budget by the number of business days left in the current month.
  13. The script applies a minimum rule to bump the allocated budget above the minimum daily budget.
  14. It handles traffic budgets separately by copying over the budgets and blanking out the budget for non-traffic campaigns.
  15. The script calculates the Salesforce Item ID-level pacing compliance percentage.
  16. It checks for changes in the allocated budgets and constructs the outputDf with the changed campaigns.
  17. If no changes are detected, it returns an empty dataframe as the output.
