Would google combine a subdomain name and domain name for keywords in a search or would it treat them completely separate? For example, If my keywords were "coca" "cola" and cocacola.com was not available but I instead bought cola.com and used coca as a subdomain so it was coca.cola.com. Would google give that more value than cola.com/coca? Would you be better off just finding a domain name that worked like mycocacola.com? Just adding a word to your domain to make sure you get both words in the main domain name?
Hopefully that makes sense. I have a feeling getting both keywords in the main domain will be given much more value than one as the subdomain but just curious to what everyone thinks.
Ps. I'm not actually trying to rank for the keywords coca cola. Just happen to be sipping from one as I wrote this :p
