Is there any common wisdom on how important it is to have the same domain name and site name? I've realized I need to make a change, and I came up with domain name that is going to help me greatly with SEO, but it will be different than my site name. If I use my site name the same as my domain name it will take me a lot longer to reach the top of google for my keywords so I want to go with this other name.
Any thoughts? Do people see a problem in going this route?
