Nevery says that monthly budgeting would likely be best for "companies that see a large
fluctuation in search volume and do not want to miss opportunities by being capped by a daily campaign budget limit."
Still, advertisers should be cautious when choosing the monthly budget option, particularly when using the accelerated delivery option. "With accelerated delivery your ads will be shown as often as possible immediately, meaning that you could completely spend your entire monthly budget in a very short time," Nevery says.
