Last week, I made a prediction that StumbleUpon was on the way up again as a useful tool in the online marketing arsenal. Now, they just did themselves one better with a feature called “Explore.” Currently, the only option for discovering new pages is to choose a general category such as parenting or marketing. With Explore, you can drill down to a specific keyword like “strollers” or “email marketing software.” The problem with StumbleUpon traffic is that it’s never been highly targeted so it results in a large number of junk hits.
