Dofollow Social Bookmarking Sites

What is the purpose of dofollow bookmarking sites? How these sites will help us to increase traffic? Will they improve pagerank?
Any idea,Please reply.
Thanks

 

dofollow bookmarking site will page link juice. If linking is done properly, with proper anchor text, it will help gain serp. Yes, it will improve pagerank, but i wouldnt bother with page rank, as long as you got serp.

As for traffic, any site, dowfollow or not, can improve traffic by referral, but the whole idea of dofollow site is to improve your serp.

 

I don't beleive that only dofollow links improves SERP. Maybe only dofollow links affect PR, but they can help for rankings.

 

Dofollow means the sites that let Google index their content. So if you bookmark your website with many social bookmarking sites this is only to increase the number of backlinks and is likely to gain you better attention among search engines (SERPs).

 

where can i find dofollow social bookmarking sites? all that i use use no-follow.

 

Thank you very much for all the replies.
