Let me show you an example without any further ado:
Rule-of-the-week-budget

The idea is pretty simple: if an ad set spent over 80% of its daily budget today and performs really well then the rule would increase its budget by 25% to give it more time today to bring you additional conversions.

This rule might come in handy for any type of campaign goal basically, whether it is purchases, leadgen, link clikcs, etc. Just pick the metric that you use for campaigns optimization in the first condition. The second condition is universal and it's built using our metric comparison feature.

So if this idea seems interesting don't hesitate to give it a try yourself.
