My question is this: Say you have a 100 page site. How are you going to target each of those pages in your domain name? As we all know, SE's rank pages, not sites, so keywords in your domain is only going to be relevant up to a point, right? So, if your site is dog-accessories.com, that should help on your "dog accessories" keyword optimized page, but not sure how much help its going to be on you "dog collar", "dog bed", "chew toys", "dog leash", or the 10-20-30 other pages that don't use the keyword "dog accessories".
