I would hope that domain/key-word would rate as well as key-word.com etc. , it seems like they should, but it also seems like a lot of peopel think they are not.
I kind of buy into the key-word.com being a bonus if for no other reason than it's a form of anchor text keywording on all incoming links. That makes sense to me, but that does not mean it's correct.
I have also read the subdomains do not inherit the same magic as root domains on google, but you know what they say about opinions, and if its primarily a function of the key word being included in all links then domain - subdomain should not matter .
I was hoping someone had tried an experiement, I guess we will see what others say.
As to monkey fighting, it's the direct replacement to MMA, so don't nock it until you have tried it! ( for the humorless readers this is a joke, I do not sponsor, participate in, or condone cruelty to animals )
