Key word in domian name?

[seosean]

Typically I go with the one without a hyphen - Google should be suffocated enough to distinguish between them.

For short names, i.e. 3 words or less, I think it is best to go without the hyphens. It makes it easy for a person to enter and the hyphens don't seem to add anything.

If I were you I would avoid dashes.

keyword in domain name is best for SEO

domain-name.com is more better

[besteast]

I think domain-name.com is better, use hyphens in your domain name rather than spaces or underline.
I think using keyword in domain name is benefit to website rankings. Make sure that your domain name can be easily accepted and remembered by customers and visitors.

paces or underline

According to the ICANN rules you are not allowed such symbols in the domain names

My experience is that it has made a difference in the overall ranking. If used correctly both will work. But, that said I ill always try and go without hyphens. I purchase and publish a minimum of 5 new URLs a month.
