Sites like digg.com, reddit.com, stumbleupon.com etc can bring you a LOT of traffic. How about getting 20,000 and more visitors a day when your listing hits the front page?
Getting to the front page of these sites is not as difficult as it seems. I have been successful with digg and del.icio.us multiple times and have thus compiled a list of steps that have helped me succeed:
1.Build a top-profile
2. Pay attention to your Headlines
3. Write a meaningful & short description
4. Make it easy for others to vote / bookmark your site
5. Submit to the right category
6.Do not use automated submitters
Hope this will help you friends...
