I'm going to buy an PR 4 + aged domain & then re-direct it to my affiliate site. So, i have a few 'straight to the point' questions 1) If the domain is already active( NOT EXPIRED ) so when i buy it it's good to enable whois privacy? If the domain is expired & i purchase it is there any use? 2) If the domain has content ( but irrelevant ) should i change the content to relevant ones ( should i add the relevant ones OR delete the irrelevant ones & start adding from new ?) If the domain has no content can i add anything to it OR should i look up archive.org & add that content ? 3) Its goo that i re-direct immediately or hold on for a while, add content, build back links & then re-direct it? 4) Does the back links built to it must be of the anchor text used for the affiliate site? or any different anchor profile? thank you very much for taking the care to answer this. field experiences will be appreciated very very much.
