i am just wondering if one of the following ways of using keywords in a url is better for serp's than the other. the scenario is; i am selling leather dog leads and wanting to reach customers searching for "dog leads leather" there are two possible ways of structuring my domain to include the keywords into the url. option 1> url/www.dogs.com/leads/leather.htm domain = dogs directory = leads page = leather option 2> url/www.dogs.com/leads-leather.htm domain = dogs page = leads-leather which of the above if any would perform better in search engine results? does a domain/directory/page rank perform any better or worse than domain/page?
