Hello all, This is my first post here and I'm pretty new to all of this so any help would be really appreciated. I am using direct links on my website (with propeller ads) and I'm using a variety of traffic exchanges to send traffic using a shortened google link for tracking purposes. I've already geo-targeted my traffic to match the highest CPM rate countries that propeller ads showed on the revenue breakdown page. My question is this: does the referrer website have an impact on CPM rate? So, would it make a difference to the CPM rate if the majority of my traffic was direct, from search engines or social media for example... Any help or advice is much appreciated. Cheers!
