I am currently in the process of setting up a Search Portfolio. I have two main objectives (leads and revenue) and all the campaigns lead to both those objectives. Should all those campaigns be in 1 Portfolio? Or should I restructure my campaigns so there is 1 clear objective for the campaigns?
At the most basic level, I am asking if its better to have more campaigns in a Portfolio or less? Also, is it recommended that I have only 1 metric in the Objective?
