Does social bookmarking really work?

Hello, I'm ghdfans2010. I'm back now. Last post I tell you about the traffic of our website. This problem still doesn't solved. There are another problem. As you may hear, there are many SEO experts saying that social_bookmarking can bring lots of traffic to your website. However, I have keeping updating the social_bookmarking websites such as Myspace and Blogger for about two weeks. Everyday I will update a new article to all the blog.There are not any traffic to our website. What's the reason? Does social_bookmarking really work? Or our site inherent problem? Who can help me? Why do we have any orders for about two month'optimization? I need your help?
Looking forward to your reply.

get top bookmarks sites and put your link on this sites

Don't post duplicate content and use facebook for traffic.

it's useful

Submit your sites to the bookmarking sites whose traffic is higher enough. If you use blogger, then do some tweets about that.

Yes social bookmarking really works.
with the help of social bookmarking you can easily increase your site traffic.

Sure it works, but you should post regularly and your posting should have good quality to drive traffic.

Definitely, but not all book marking site. Digg, diigo, stumble, reddit, and delicious are most important sites which provides traffic.

First of all you have to understand one thing, myspace and blogger are NOT social bookmarks sites, those are social networks & blogging sites. You have to have more traffic to your blog inorder to drive traffic from the blog to your site.

As well as, it is better to apply all the available ways to get backlinks to your site rather sticking with only few methods.
