When you’re out there in the search engine optimisation trenches conscientiously building backlinks for your website; which domain variation are you using? Here are the 4 possible choices:
When either one of these is typed into an Internet browser they will all take you to the same place – straight to your homepage; therefore does it really matter which one you use in your backlink? Well not really. But whatever one you decide to use, you want to stick with it.
The next time that Google comes along to update the pagerank of your homepage you want to make sure that the majority of your backlinks are pointing to only one variation of your domain name so that you aren’t sharing your pagerank between all 4 variations.
For example, if you use all the above variations in your backlinks you might find that you have this problem:
* www.yoursite.com (PR1)
* yoursite.com (PR2)
* www.yoursite.com/index.html (PR1)
* yoursite.com/index.html (PR1)
When what you really want is this:
* www.yoursite.com (PR0)
* yoursite.com (PR4)
* www.yoursite.com/index.html (PR0)
* yoursite.com/index.html (PR0)
Whatever variation you decide to go with, you want to stick with it so that you can funnel all your pagerank to just one variation of your domain name.
To you and me, all 4 look the same in the browser, but to the search engine spiders they are 4 completely different web pages; so when evaluating the PR they look at each variation individually.
So the answer is that it doesn’t matter which variation you use in your backlinks – but choose one and stick with it so that you can get the PR of your homepage as high as possible.
