I like that we can easily create our own campaigns for marketing purposes (we've recently started doing this).
Also it's easy when using Google Analytics or other tools to add custom metrics into the platform as well! We are looking forward having more options with regards to targeting ads through Upchannel when choosing between PPC and CPC in order to reach specific audiences by offering the best value per impression/click. Currently not much because still new at upchannel but what i do know is how great they have been helping us improve ROI on all ad formats - so far no complaints from my side :) Have used them mainly for their CPA management service where we pay only if someone clicks an advertisement instead of paying each time one visits one of Upchannel's websites.
