Hiii Guys, Linking is a concept to get the good inbound links from different known websites. Google emphasise on good inbound links and calculate popularity of particular website. But now a days it is not necessory if you are having so much of inbound links with your site until unless you are having inbound links from popular sites because Google checks popularity of links with no. of backlinks you are having. In my knowledge linking is very much worthy for any site to get high ranking in any known search engine but links should be good and popular..
