Efficiency of StumbleUpon advertising ?
jreposa: In our experience, we received a high bounce rate of 80+% and about a 20 second time spent on page. This is definitely some of the worst traffic you can get. Some days you'll get much worse results, like 95% bounce and 8 seconds on page.Keep in mind that once you put the money in, you can't get it out. So, even if you do test, put the minimum amount of money in.
