As a best practice, it is recommended to check spending, delivery, and performance throughout the week. Why this this a best practice?

Regularly checking spending, delivery, and performance throughout the week is a best practice because it allows you to identify and address potential issues or capitalize on opportunities promptly. For example, if an ad set is underperforming or overspending, early detection enables you to pause or adjust it before significant budget is wasted. Conversely, if an ad set is performing exceptionally well, you can allocate more budget to it to maximize results. This proactive management helps optimize campaign efficiency and effectiveness. It doesn't guarantee better performance, as many factors influence results, nor does it guarantee better auction pricing or that you'll never overspend, though it significantly reduces the risk of the latter.
