301 Redirects Do Not Pass Full PageRank & Link Value

Eric Enge interviewed Matt Cutts of Google and uncovered a few interesting tidbits about Google, but the most significant piece of information was that 301 redirects do not fully pass the PageRank from the redirect. Let me quote you the interview from that piece:

Eric Enge: Let’s say you move from one domain to another and you write yourself a nice little statement that basically instructs the search engine and, any user agent on how to remap from one domain to the other. In a scenario like this, is there some loss in PageRank that can take place simply because the user who originally implemented a link to the site didn't link to it on the new domain?

Matt Cutts: That's a good question, and I am not 100 percent sure about the answer. 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).

Whenever you move a URL or a domain name, we are told by Google to use a 301 redirect, if we cannot keep the existing domain or URL. We were also told that a 301 redirect would pass the PageRank. But that is not fully true. As you can see from the interview above. Some of the PageRank from the redirected URL will be lost. How much exactly? That is hard to say but some is lost.

I personally never like changing URLs but sometimes you don't have a choice.

MarsEdit 4

I've been using MarsEdit for just over seven years. I started with version 2, and then upgraded to version 3 in 2010.Now, in 2018, I just upgraded to version 4. This is my first post with the upgrade and I'll report on it in a little while as I get used to the new version.Here is what Daniel of Red Sweater Software has to say about his product:Browser-based interfaces are slow, clumsy, and require you to be online just to use them. Browsers are perfect for reading web content, but not ideal for creating it. If you're serious about writing for the web, you need a desktop blog editor.

Resistance Is Futile

Some of the trains that run from London Kings Cross to Cambridge divide at Cambridge. Part of the train goes on to Kings Lynn and the rest stops at Cambridge and does the run back to London. Perhaps it picks up other carriages coming from somewhere else, I don’t know but it seems likely.When you get on the train and before it sets off, there’s a public announcement announcing how the train divides. It explains that the train is composed of eight carriages and that passengers wanting to travel beyond Cambridge should ensure that they are in the front four carriages.The rear four carriages are of course nearest the barrier, so we choose to sit in one of those carriages if for no other reason than that we don’t have to walk so far to find a seat.So there we are and the voice comes over with the announcement. And then there is a pause and then a voice tells you what carriage you are in. So we hear ‘Six of Eight’ or ‘Seven of Eight’ – and every time I hear it I think of Star Trek, ‘Three o…

Business For Britain Is Concerned With Business For Britain

This report in the New York Times today


LONDON — Is British business fretting about the risks of the country drifting out of the European Union? Or does it crave a looser relationship with Continental allies, one free from meddlesome regulation?
The answer to that question remained unclear Monday after a newly formed group of business leaders argued for a renegotiation of Britain’s membership terms — echoing the policy of Prime Minister David Cameron, who in January promised voters a referendum on whether the country would remain in the Union.
The new group, called Business for Britain, is intended to counter the intervention of pro-E.U. business leaders who have warned of the dangers of Britain slipping out of the 27-nation bloc and its single market of 500 million people. A statement released Monday to announce the group’s formation was signed by about 500 executives.
I think this opinion in the New York Times article is interesting:

Never much attracted to the idea of European unity,…
