Just a few weeks ago, people started noticing that the Yahoo Directory lost Google PageRank. Well, not the home page of the Yahoo Directory, but the inside directory listing pages. The pages that link to your site and, in the past, past PageRank and link juice.
I am skimming through the pages, even the pages closest to the top of the directory are showing nothing in terms of Google PageRank. For example, the arts section or the WebmasterWorld thread it might be due to how the URLs are set up.
It seems to me that the Yahoo directory is grey barred because its got no pagerank, because the links from the home page http://dir.yahoo.com/ are all via non-search engine friendly redirects like: http://us.rd.yahoo.com/dir/home/cats/*http://dir.yahoo.com/Recreation/Travel/
But that doesn't completely jive with me. I know I have personally linked to many of the non-redirected linked versions of the directory pages. Some of those pages should have PageRank, no?
So is the Yahoo Directory still passing value? I assume many would say yes. What is up with the zero PageRank score for all the internal pages?
Forum discussion at WebmasterWorld.
Update: I have posted an update named Google Says, Yahoo Directory Does Have PageRank.
