I feel the term “SEO” is completely overused, however, there are a few things you want to do besides just having great content. One is make sure your site url is consistent. chrisbitting.com is different from http://www.chrisbitting.com. 

Google Analytics will provide you a suggestion to fix this if you’re experiencing traffic from multiple hostnames. Something like:

Property http://www.yourdomain.com is receiving data from redundant hostnames. Some of the redundant hostnames are:

• yourdomain.com
• http://www.yourdomain.com

This is easy to fix using your Global.asax page. Just add this to your code, replacing “yourdomain” with your actual domain. The Application_BeginRequest will catch and redirect to the altered url, also issuing a 301 to help search engines.

void Application_BeginRequest(object sender, EventArgs e)
    {
        

        if (HttpContext.Current.Request.Url.ToString().ToLower().Contains(

            "http://yourdomain.com"))
        {

            HttpContext.Current.Response.Status = "301 Moved Permanently";

            HttpContext.Current.Response.AddHeader("Location",

                HttpContext.Current.Request.Url.AbsoluteUri.ToString().ToLower().Replace(

                    "http://yourdomain.com", "http://www.yourdomain.com"));

            HttpContext.Current.Response.End();
        }
    }

You could do this using web.config + rewrite, but I enjoy this method more.
