Well this must be true in any case but I usually use boomarking to let visitor notice my site and somehow get some quality visitor who will stay for you every once in a while and not for keyword purposes.
nice posting and i have a social bookmarking site list i want sharing with every one social-bookmarking-sites-list.com/
Great list. Take advantage of those free and "dofollow" bookmarking sites, because that would help you in driving traffic to your website,combined with other organic link building strategies.
It seems like everyone just keep saying what a great list is. Guys HELLO! Most of them are waste of your time. They don't exist!
There are a wide range of lists available, but I suggest focus on your niche and get quality backlinks. It really helps shoot you up to top of Google.
