Do you use StumbleUpon for free traffic? I just read that last week, StumbleUpon released a new app for iPad and iPhone that is optimized for the "iPad experience". So far, it’s received a lot of really good feedback, and as we all already know, the iPad market represents a great opportunity for fresh traffic.

Top that off with Statcounter showing that StumbleUpon topped Facebook as the #1 source of social media traffic in the U.S. with 43% compared to Facebook’s 38% (see graph).

So what can we do to take advantage of this? Here are a few tips that may help:
1. Create content that people are likely to find entertaining, interesting, important, or just plain cool.
2. Build a network of StumbleUpon friends.
3. Don’t just stumble your own stuff (though I personally don’t think it hurts to do it sometimes). I wouldn’t do everything you create though.
4. Find things that haven’t been submitted to StumbleUpon yet, but you think others will find interesting, entertaining, important or cool, and submit them.
5. “Like” things that have already been submitted that you find interesting, entertaining, important or cool.
6. Use as many relevant topic categories as makes sense when submitting something. This should help target it to the right crowds.
7. Reviews are optional, but it can’t hurt to write them.
8. Making content visually appealing with use of pictures or videos can lead to more stumbles.
9 . Use the Stumble button on your content
10. Promote your own StumbleUpon presence.
11. Use StumbleUpon’s paid options.

Are you working with StumbleUpon traffic? If yes, I would love to hear your stories on what you did and how it resulted for you.
