In this exercise let’s practice finding campaigns with a high CPC. It’ll help us to identify campaigns that don’t perform well and should be carefully observed and maybe even shut down.
In the previous lesson we saw how easy it is to calculate CPC for a campaign on a certain day. Let’s piggyback on that and find what campaign historically had the highest ever CPC on any day.
Type in the utm_campaign of the campaign that had the highest CPC on any day.
