Yesterday, I wrote about how to redirect www URL to non-www URL (and vice versa). Today, I am going to write about the next natural question: which URL format is better? Should you use www URLs or non-www URLs? Which one of these is better from the SEO point of view? And what exactly is the difference between www and non-www URLs? These are questions that come up in every new webmaster’s mind. Let’s dig a bit deeper and gain understanding of this www vs non-www business!
Let me be straight to the point in the beginning. Both www and non-www URL formats are equal. Neither is better than the other. So, you can use either of the format, it’s totally your personal choice. But it is highly recommended that you use only one format. Either stick to www or consistently use non-www format. Google Webmaster tools allow you to set your preferred domain (http://www.example.com or ). And therefore Google states that it does not care which one you use.
There are two distinct aspects of this issue. One is SEO aspect and the other is technical (DNS stuff). Let’s examine them further.
I know you still want to ask, “ok, all that is fine, but still which format is really better?” Well, as I said, it all depends on personal preference. All I can do is to tell you a few more bits of important information. Then you can decide for yourself.
www URL format is better because most people remember URLs that way. “www” is etched in people’s memory and most people who are not tech-savvy, often speak and write URLs beginning with www. Therefore, www format has a mnemonic advantage over non-www.
non-www format is shorter. So, it requires less efforts and occupies less space. Honestly, for me typing three Ws is irritating. Therefore, I love to use non-www format! Yes, it is as simple as that!
If your website is small (that would include websites with millions of pageviews per month) then there is no problem. But if your website is massive (millions of pageviews per day) then you may require to deploy redundant hosts. Redundant hosts are computer servers that all keep a copy of your website. If one of these machines gets overloaded with traffic, the traffic is automatically redirected to the other machine in the array.
These redundant hosts are defined using CNAME records. But because non-www domain can not have a CNAME record, you will not be able to set it all up!
All this technical superiority of www format will arise only when your website will become a mega website. Until then you can be rest assured that www vs non-www issue does not affect your website’s performance or ranking.
“What? Canonicalization? What on the earth is that?!”
Most newbies ask this question! The word indeed sounds weird. I had to practice it to be able to pronounce it correct. And still I hardly can speak this tongue-twister. Anyway, canonicalization is the process through which a search engine decides which URL to select and keep in its index. As Matt Cutts has explained it, if there are several URLs, all pointing to the same resource, canonicalization process decides which one of these URLs is best. For example, all of the following URLs may point to the same resource:
How does Google decides which URL to pick? Only Google knows! But one thing is certain, Google does give a lot of importance to the most consistent format. That is why consistency in URL format is important.
Two important tools can help you in achieving the said consistency. One is, of course, Google Webmasters Tools. Here you can select preferred domain for your website. Just log into Google Webmaster Tools and then go to Site Settings by clicking on the wheel icon:
In Site Settings, you can make your choice of preferred domain.
If you are running a self hosted WordPress website, the second tool which can make you life easier is WordPress SEO by Yoast. This superb plugin allows you to setup a preferred domain name and then output all the URLs only in that chosen format.
If you have been using non-www format and now want to change it to the www one; you should setup a 301 redirect so that your links remain valid.
Do not panic! Either of the format is equally good. Even Twitter uses the non-www format (naked domain). So not worry and just focus on producing good stuff for your website or blog. And you’ll be all fine!
