301 URL redirect at script | SEO Practices | DinoRiese.com
Creating a URL redirect with a 301 redirect will allow your website to be accessed without placing the "www" in front of your domain name in an address bar raw search. By doing this you recycle all the user data that would have went to the link without the "www' in the address bar & vice versa.
This is important for measuring your user data and getting extreme accuracy. Once you have done this, you will then start fresh with your analytics account, and get better results for accurate user traffic.
