So I have found a nice 10 year old domain in my niche that was dropped. Link profile was nothing extraordinary, about 100 linking domains, couple PR1s and PR2s, but in archive.org I saw it had lots of real high quality content so I registered it. About a week after it was indexed I saw the homepage pagerank jump to 5. I was like wtf? Checked link profile again but couldn't find the source of the juice. So I thought maybe somebody was trying to auction it before it expired and faked the pagerank. The next PR update should sort it out. Now this is the weird part. Yesterday there was a PR update. The PR5 homepage remained PR5, but all the inner pages are PR N/A just like before the update. My confusion: If there is an active redirect pointing to the domain, the inner pages should have picked up pagerank. Same if it's genuine PageRank. If there was a redirect that has already been removed, then the homepage Pagerank should have dropped. I am not fixated on pagerank, this is just something that doesn't make sense to me logically. Any ideas?
