Just for example, let's say my niche is lose weight now
if I end up only being able to find a domain name by the name
losebellyfatnow.com or lose-belly-fat-now.com does it matter? Is one better then the other? Yes I know without the hyphens it looks more professional but results wise, how do you know which one is better?
I really need someone to go into seo when it comes to domain name, thanks guys!
