"If we have lets say same backlinks and same other seo stuff who would rank higher?" >> Depends on any other factors like OnPage-SEO, trust-factors (like age of backlinks, age of domain, etc) >> I guess the older domain will win. "Question #2: I am using a wordpress site for my movie site: I see many sites have domainname/watch-movies-online/ but in wordpress you have also the option to use url without the hyphens between the words. Which one is better for seo?" >> People say that phrases without hyphens are better rated. But that's just a slighly difference. In my opinion it's better to use hyphen, because it's much better readable.
