1. Lookup canonicalization to get a better understanding of how Google and others see your site. Even though one is www and one doesn't have that...Google will probably see it as two sites. There are many fixes so that you don't have to really worry about that anymore. 2. What was number 1? Your site name, or a keyword? Let us know what domain you are talking about, and maybe we can help
*create a permanent redirection to non-www to www version so that SE recognize it as one.. IBL can also be different.. *as long as the site is index its not ban..
