PPC is becoming a bigger part of my business, and I'm starting to realize some merchants track things in ways that make it difficult to measure PPC effectivenes and ROI. From what I've seen most merchants fal into three broad categories.
Subscrption based merchants count a sale within a few hours of it being completed. Other than diffrent systems using GMT, EST and PST this is pretty easy to measure. Most merchants report the sale when the item shipped. So the $50 you spent on clicks today may be reported as sales over the next 1-5 days, this is harder to measure. Some merchants only update once a week. This makes it really hard to test a new PPC campaign, as you could go through money really quickly without having an idea if it working or not. I'm looking for sugggestions on how to more effectively manage, track, and measure ROI for some of the longer time frame merchants. Any Ideas?
