I was looking at buying a few old domains that have decent PR already in order to help another site gain PR. For example I might buy A.com (which has, say, PR4 already) in order to give B.com some PR. I was going to simply put a link to B.com from A.com (with keywords in the anchor text), and so pass on the PR in the standard way. However I was wondering if I instead put a 301 redirect from A.com to B.com, would the backlinks that give A.com its PR then give B.com the same PR, or does it not work that way? This would help with traffic too if A is in a similar field to B. Thanks.
Well I could put new content on A.com to make it related to B.com I guess, since with most domains it is hard to tell from just the domain name what the site is about. Although I guess Google would know from its cache what it was before... But I have wondered about this "related sites" aspect before. The thing is that this would mean that even if you got a direct link from Google's home page to your site it would not get much PR (unless your site is search engine related)? Or maybe it would get some, just not as much as if you were also running a search engine..? Has anyone bought an unrelated domain for its PR a few months ago and seen their PR rise accordingly in the latest update?
