Well, when you search for some “damn” thing, the first result that view in Google would be from Wikipedia. How did Wikipedia grow this much ?
The answer lies on various things. The first and foremost is the PageRank of Wikipedia (its 9 !). But there are various other things which make it rank better than other sites. The next important criteria is the number of inbound links.
Inbound links are always good, when you use it in a right way. Inbound links should be handled carefully. Wikipedia has done that excellently. For all the Wikipedia pages you should view atleast 20+ inbound links to Wikipedia’s other pages. This makes the user and Google interlink the concepts.
Well because of these things Wikipedia always ranks better !
