As you know Stumbleupon can literally drive thousands of dailly uniques to your site. Here are soem tips to help you out:

1. Commit to making the effort to become part of the StumbleUpon community.

2. Don’t obsess over becoming a ‘power Stumbler’. Content is what matters most.

3. Become an active stumbler. Review and rate as many sites as you can.

4. Install the toolbar. Choose your subject preferences. Start stumbling sites that interest you.

5. Stumble your own stuff from time to time.

6. Don’t lead stumblers to your blog or website main page! Link deep to individual posts or articles.

7. Target your audience. Focus content to their interests.

8. Create longer posts with more links. Every thumbs up you get increases traffic.

9. Label and tag your submitted pages appropriately. Broad tagging helps. Go after keywords that are popular and often searched.

10. Don’t overwhelm your page with ads or distractions. Don’t ‘hard sell’ SU visitors.

11. It all happens ‘above the scroll’. Use a powerful title and visual cues to grab interest.

12. Build relationships on StumbleUpon. Don’t take a narrow, short term view.

13. Your StumbleUpon profile is important. Get more exposure/fans to your SU profile.

14. Link out to other bloggers who use StumbleUpon. Stumble the posts that link to you.

15. Thank people who stumble you. They’ll remember you - because not many do it.

16. Personalize your ‘About’ page. Plan what goes on it carefully.

17. Join the communities relating to your interests and your business.
