Hello all ! We have ever seen page rank of each site .Lowest rank is zero and highest is ten.But can any one tell that which algorithm Google is following to decide a page rank for a site. Thank you !
Google has a set algorithm for determining PR and updates it few times a year. Next it will be updated on 30th January. Best wishes.
I think one of the important factors is backlinks.Google checks the number of backlinks and the quality of those backlinks.
