I quickly realized that StumbleUpon is the coolest and hottest social bookmarking service nobody has heard of.  I love it but I don’t nearly use it enough: either as a stumbler or as a marketer. I found this on Blog Marketing Journal and thought I would open it up to you:

In case you are not familiar with the concept, StumbleUpon allows you to pay for visitors to your pages, five cents per visitor or click. The question is, do you consider this to be a simple form of paid advertising, or paid social bookmarking.

I have done some experiments with paid Stumbling and what BMJ says is true:

If you set a limit of $20 per day, you will get 400 visitors. They may stay on your page or they may spend five seconds and disappear. Where the situations changes is when they thumbs up your page. That’s a stumble and can lead to more than just the 400 visitors.

So, in this case, content is key, and good content will result in conversions and interest.  If you just throw money at it without thinking your content or strategy through, you will be disappointed with the results, especially since there’s nobody on the planet more savvy than the gang from StumbleUpon — these are earl-adopters and are just the people you want to love you but these are the worse people to piss off. Just because you’re paying to have your content promoted doesn’t mean that people are prevented from digging the content down (thumbs-down) or writing scathing comments.

Either way, I encourage you to install the Firefox or Internet Explorer plugin and start playing with it — you need to register first, of course. I also encourage you to throw some money at the pay-to-play paid StumbleUpon advertising scheme — it is amazing fun and if you have any cool content at all, it is so much more rewarding that trying to game digg or even organically start StumbleLove — if you’re not really into Stumbling (I have friends who actually spend their evenings Stumbling in lieu of TV) then paying to get started is a very good idea and worth a test — you can check out the FAQ first:
