From now on we'll be trying to make video tips every week. So here is the first one:

And here it is on a screenshot:

When an ad set spends more than $100 in the last 3 days including today and it has a great ROAS this rule would remove ONE_HUNDRED$ from its name and add TWO_HUNDRED$ instead. The use of the name contains/doesn't contain filter is absolutely nessesary so that you don't keep adding something to the names, making them 400 charaters long. Watch the video for more details ;)

And if you have any doutbs over how to set a rule up please don't hesitate to ask. Cheers!
