Does social bookmarking really work?

I advise to use onlywire for submission. Relevant keywords to your site in the title. After that you ping all that social sites. You can use pingomatic or pingler. Do this and will see some traffic.

I agree with Julcash, don't forget to ping all the social sites, I use pingomatic.

yes, social bookmarking is work really hard.
it is a best way to get high PR and increase website traffic..

Yes, social bookmarking still work but you need also to mix with other techniques and not just depending only to one strategy.

Submit your post in the social bookmarking site which is having a page rank and then tell me the result of your keywords..It really worked for me..

Ofcourse social bookmarking works, if it didn't not many people would be flocking to it

Yes, it does bring in a good amount of traffic. One thing to remember is this traffic might not always convert well.

SEO manual submission is the ideal and the most convenient way to get you site indexed on popular search engines.
