Some Big Websites Suck at Non-WWW to WWW Redirects

Alright, folks. Today we’re going to talk about PageRank. Oh, I know. It’s dying and/or dead. Ok. Awesome. But it’s still a metric that we can use… at least a little. Like in this post, which happens to be about people not correctly redirecting their homepage URL from the non-www to www version.

Alright, folks. Today we’re going to talk about PageRank. Oh, I know. It’s dying and/or dead. Ok. Awesome. But it’s still a metric that we can use… at least a little. Like in this post, which happens to be about people not correctly redirecting their homepage URL from the non-www to www version.

I’m going to assume you know the advantages of redirecting the non-www version of your site to the www version of the site. Across all pages. Or maybe you prefer to go the other way – swim up stream like I do with this site’s URLs – and redirect the www version to the non-www version. It’s all about eliminating duplicate content and making sure every link is most effectively attributed to the ‘official’ URL for your product pages, category pages, etc… Blah blah blah.

Here are some sites that do this very efficiently and effectively (and their respective PageRank values):

So fresh and so clean clean: Awesome examples of non-www to www via 301 redirects

It’s so nice to see this being done correctly. And these are some bigtime brands. Well done, big brand sites. Well, done.

In March 2010, Matt Cutts dropped some knowledge on us:

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 really, we shouldn’t think of this non-www to www redirect method as something that is going to pass all of our linkjuice and PageRank through to the final URL. It simply doesn’t work that way. However, it still passes some PageRank AND it helps reduce duplicate content. And that’s good enough for me.

So…the awesome examples were just the beginning of this post. Now we’re going to see some websites that are losing a lot of link juice from doing it all wrong.

First, let’s take a look at sites that do not use any type of non-www to www redirect. And again, these are some big brand names right here:

These sites need to join the party: Go ahead and 301 those non-www's already!

Wow! Sprint has the PR8. That’s impressive. But what would it be if you 301’d the 4,280 links that are currently pointing to the non-www homepage URL? If you wanted to go buy 4,280 links, that would be pretty expensive. You could pass all that linkjuice to the www version of your site – FOR FREE! How about that? That’s 4% of your total links to the non-www version of your site! And you could at least get some of that linkjuice. [BTW I got the external link numbers from SEOmoz’s Open Site Explorer tool.] The point is: Returning a 200OK for your non-www and www homepage URL isn’t terrible, but it’s not up-to-date with fundamental SEO principles.

Now here are some sites that are doing the non-www to www redirect, but these sites all share the honor of having used the dreaded 302 temporary redirect. In general, the 302 redirect is the ‘Voldemort’ of SEO. You really don’t want to be caught mentioning it – ever. The 302 has its place, but it certainly is not needed in this conversation. Mainly, we don’t want to use a 302 for this because it does not pass any linkjuice. So here are some big sites that are using a 302 redirect from the non-www to the www version of their sites:

I won't tell anyone. Just please change that to a 301 redirect. Already even!

Really, Apple? Really, Costo? Really, Walgreens? I’m just going to assume that you all have awesome SEOs who know what they are doing. Obviously there is a perfectly good reason for your sites to be using the 302 redirect for non-www to www. It’s probably classified. I’m going to give you the benefit of the doubt. Regardless, I still recommend that you update that redirect to a 301. It would make me happy. Because I’m an SEO nerd, and even more specifically – I want to see Apple at a PR10. I mean, maybe the linkjuice from another 114,524 links would help to get to PR10. I dunno. But it certainly wouldn’t hurt.

Let’s dive into some other sites that are really screwing the pooch. As you will see in the following screenshot, some websites prefer to use *double* redirects and, yes, even *triple* redirects to get from the non-www to the www version of the homepage URL:

Chain chain chain: Redirect chain of fools.
Chain chain chain: Redirect chain of fools.

To me, the double redirects and triple redirects look like a chain. Just imagine all the PageRank that is lost, siphoned off with each redirect. It’s terrible. Simply terrible. Verizon, I am a customer of yours. In general, I think you service is great. But it pains me to see a double 302 redirect on your homepage. Please fix that. Please. For the love… This is just depressing.

Finally, I found a website that is guilty of something that I can barely bring myself to discuss. From a usability standpoint, it makes my blood boil with the rage of 1,000 SuperBowl-week ice storms. This site does not load when you visit their non-www homepage URL:

The unforgivable sin of usability: homepage URL unreachable

Okay. Hahaha. Get your mind out of the gutter. BJ’s is a Fortune 500 company and a wholesale club. Now, redirecting the non-www to www is one thing. But in this case, basic web design and usability principles override SEO practices. It’s imperative that they at least get the non-www version of their homepage to return the actual homepage of their site, even if it is a 200OK. Even that would be better than the current scenario. I urge everyone to make sure this is not happening with your site. Please go check. You’ll feel better if you do. I promise.

Well, that’s pretty much it. In conclusion:

  • 301’s are good, and 302’s are generally bad
  • non-www to www redirects can help increase your homepage URL’s PageRank
  • double redirects and triple redirects are not good
  • bjs.com is a respectable Fortune 500 wholesale company

Now get out there and take a look at your .htaccess file(s)!

Cheers!
