But I have a question how does it helps to get high PR - I mean, how it is beneficial to SEO? A confusion develop in my mind that if I just register to a social site and bookmark my site but I do not have any friends in my social account - is it then helpful; bcz how others (as I have no friends in the list there) will got notified about the site that can generate traffics to my site?
I think I am able to make u understand my confusion. Please help me to get it clearly.
Social media sites will do little, if anything, for your search rankings. They won't get high PageRank. They won't pass much, if any, googlejuice. The reason for this is that Google will not pay them much attention as they're too easy to manipulate.
The reason for using social media sites is to get direct traffic from real people clicking on a link - not to improve your search position.
Any posts I write in Arial are on my mobile phone, so please excuse typos etc. Any posts I write in Verdana are on a PC, so feel free to berate me mercilessly for any mistakes
