I have never considered CTR to be relevant.. In fact, I actually use my banners/spots to filter out traffic and begin pitch continuity. The only thing that matters to me is EPC.
Blows my mind watching some of these larger buyers only focus on tracking and click performance. Granted, rotating offers to align processing with X country is extremely important.. But huge (and I mean absolutely huge) money is left on the table by ad buyers who sling terrible generic landers/front ends with zero pitch/branding continuity through to join (trust building at a glance).
But I'm grateful.. It's exactly these oversights that allow me (a smedium buyer) to compete
Thommy,
While I don't agree with you politically.. You've made some very estute business related posts. Although I mainly buy us-geo, I'll have to give Traffic Fabrik a look
Clicked traffic is a personal favorite.
