Social bookmarking and earning

[shyampc]

I had bookmarked my websites to 100 social bookmarking websites, and after this I could notice a huge difference in traffic for many days. This also helped me in conversions at those days.
I had hired an experienced person to do the job of submission, and the amount spent on this was really worth.
Now I want to do this again. But, are there any ways to submit the same websites to those social bookmarking websites and get the traffic and conversions again and again? Are there any suggestions to do this?
I am planning to create blogs and display products there. Then I will be able to submit those blogs to these websites. Will this help?
