There are no where can share pagerank to you, you must to building backlinks to increase your pagerank.
Definitely - As soon as I Post new articles I will automatically Facebook and Twitter post them - then I will also post the link on the facebook fan page, Ive been doing this since April, and I've seen a 20% rise in traffic month on month.
Most of bookmarking sites have a high page rank and also great traffic. getting backlink to your site can boost your Google and other search engine.
Social Bookmarking will not distribute any page rank to your websites rather than good presence with in the web. Social book marking sites acts as index columns in our book shelf.
Yes it is good but from the point of view of traffic not necessarily for back links. Well all the main social sites have higher PR but not passing link juice to your web because most from them links your web with no-follow attribute and this type of property of a link restrict to spider to crawl on them. Not necessary that doing this will help to increases PR. Pr is the only concern with the more and more do-follow back links from some PR pages of a web site.
yes, as the social bookmarking sites themselves have good PR, A link coming from that Site into Your Site, will increase ur PR too. Cheers.
Not all backlinks are created equal. Only backlinks that transfer link juice to your site will help increase your PR.
PR juice extraction from Social Bookmarking is a hard task... only top links with low-bounce rate can get PageRank any how but these days only possible through Link Baiting Process
Social book marking alone not bring you page rank. you need to work in a versatile manner like article, directory, social network and all.
Here's a hint. Go to your favorite social bookmarking site and look at the source code. Once you have the source code open search for the phrase, "nofollow". if you find it applied to the whole page, or to the outbound link which is the main focus of the page, then you will not get an increase in PR by posting on that site. If, however, you do not find "nofollow" in the above context, then you might get PR (assuming that Google hasn't blacklisted the site as a reference for PR credit".
Most of bookmarking sites have a high page rank and crawl by daily basis.. if you submit your site in social bookmarking site who give dofollow links then sure PR flow and you got advantage.. thank's
