Just in 3 months ... example -Trust factor of the domain // Yea it is the main factor to get the best .. its (( Content )) by it we will get trust of google -How many times your link has been mentioned and hundreds more than just PR .. yea Sure ^^ .. So I don’t prefer to buy links just build links in famous sites for ever ^^ Note : If you get more and more trust of google ,,as we say by (( Content )) You can get the best .. Good luck
I have tested it, DP link is follow. The folllow link only applicable to profile homepage URL. Tools I tested: 1. yahoo site explorer (I found link back on my site) 2. Firefox seobook plugin.
Sorry, I not really get your question, I am a bit blur. If you are mention about search engine need to be login to see the profile (you have to be a logged in user to see user profiles), why yahoo site explorere show those links back? Sorry, if I missunderstanding your explaination.
