When running a performance campaign we have split up the campaign into multiple line items. We give each line item a different weighting of the total campaign budget. With the daily budget on campaign level being mandatory how would this affect the split of budget we set for the line items?
Total budget = $1000, daily budget = $100, 10 day campaign
3 Line Items:
LineItemA: 60% of total budget - $600 total budget
LineItemB: 30% of total budget - $300 total budget
LineItemC: 10% of total budget - $100 total budget
The 3 line items may pace slightly different over a particular day due to different targeting. Collectively their total daily spend will hit $100 and the campaign will stop serving for that day due to the $100 daily spend limit.
Are we guaranteed that by the end of the campaign, each line item would have spent in total the proportional amount of 60%, 30% and 10% of the total budget?
