Dose getting my articles on my site submitted to social bookmarking sites help with page rank? What are the benefits to social bookmarking
If the site is a dofollow and you anchor your links well, this can help with SERPs rankings and can possibly help with PR depending on the sb site's authority. Yeah, do what teampower said and have a look around the forums also for more info.
Social bookmarking can increase your traffic but when it comes to SERP it depends on the quality of bookmarking site.
