One of your line items has low performance but high delivery.How should you adjust your budget to optimize a campaign for better performance and delivery?

When a line item has low performance but high delivery, it means it's spending its budget but not achieving desired results (e.g., sales, clicks, ROAS). To optimize the campaign, you should reallocate the budget from this underperforming line item to others that are demonstrating higher performance. This strategy ensures that your budget is spent more efficiently on line items that are contributing positively to your campaign goals. Not changing the budget would allow the underperforming line item to continue consuming resources without improving overall campaign effectiveness.
