I don’t often jump into the world of SEO advice–there are plenty of excellent blogs that do that–but when Google’s Matt Cutts confirms that 301 redirects do, in fact, lose PageRank, well, that’s worth sharing.
Eric Enge gets the scoop–boy, is he gonna get a lot of backlinks from this–getting Matt Cutts to confirm something that I have suspected and cautioned clients for many years: 301′ing from an old domain to another, does result in PageRank decay. Here’s the quote:
I can certainly see how there could be some loss of PageRank. I am not 100 percent sure whether the crawling and indexing team has implemented that sort of natural PageRank decay, so I will have to go and check on that specific case. (Note: in a follow on email, Matt confirmed that this is in fact the case. There is some loss of PR through a 301).
So now you know. But, don’t stop there, read the rest of the interview, you may just learn some other propaganda SEO tips.
