Quick Theoretical question: Site A has a PR rank of 6 and a SERP rank of 1 and an age of 6. Site B is brand fu~king new. both site A and site B has same keywords in the domain. ALL ELSE EQUAL (i.e. SAME IDENTICAL BLs, articles pushing etc.) If I were cancel the domain on site A and host the pages on site B with an age of zero, how long do you think it would take to get site B to rank in PR and SERPs? I am not going to do this so I don;t care if it's a good or bad idea, I just wanted to get your input on goog's weight of site age alone in regards to issuing PR and SERP results all content and offsite SEO being equal.
