Jane Copeland wrote an interesting blog post about StumbleUpon traffic. I like what she has to say and I didn’t know that StumbleUpon revisited a website more than once. That’s good to know.
While StumbleUpon doesn’t give Search Engine Optimization link juice, it can increase your chances of getting link juice if you play it right. What you want is to encourage others to link to you, but how do you do that? If people are always Stumbling and not linking then are you really getting any benefit? I guess the key is to appeal to people who have not yet discovered your site and might want to link to you because 1) they really like what you offer and 2) they are in the same niche as you.
I’ve found that the best way to ensure that you keep targeted traffic Stumbling your sites is to use StumbleUpon in conjunction with other networking sites. For instance, BlogCatalog has a great networking tool in its groups and there are several groups devoted to social media and StumbleUpon, in particular. But those are general groups. While you want to network through those groups, you also want to network with others who blog and own websites within your niche. By networking with people within your niche at Facebook, BlogCatalog, and other such networking sites and asking them to Stumble your website or blog, you increase your chances of getting extra Search Engine Optimization link juice. Those are the people most likely to not only Stumble you, but link to you from their blog and website as well.
