Categories and Tags
In order to use Stumbleupon effectively, you need to know all the categories and tags on the website. As far as your tags are concerned, you have to aim it towards the right audience. Don’t go overboard and become too general. It’s better to stick to a certain category or niche in order to drive home relevant traffic.
Target Like-Minded People
It’s also important to target people who have similar interests. Avoid falling into the cliché of general or blatant advertising. There are two ways of doing so. Either you could observe people who appreciate your submissions and vote for them, and include them in your Stumbleupon friend's list, or you could try to find other Stumblers by doing a keyword search using “Stumblers”.
