I wanted to understand what KPI's can I promise to a prospect. Like, I've never run google ads so I don't know how much CTR, Conv. Rate etc I can expect. And I bellieve I will need that knowledge to convince a prospect to work with me. So, let's if the CPC's in a niche are from $5 - $20. What are the average KPI's I can expect and will need to be profitable if I do a decent job at google ads.
