"A rose by any other name would smell as sweet
This is a popular reference to William Shakespeare’s play Romeo and Juliet, what is special about a name? The thing we call a rose would be just as sweet-smelling if it were called something else.
I want to say there is nothing in domain name.Any name of domain will work effectively only if it has contents relevent to business.
“Search engine optimization simply has to support the business decision. You decide on domain name EXAMPLE.COM and then you work to promote it. Any competent SEO strategist can take a non-descript, generic domain name and build traffic for it in any set of keywords. The search engines don’t care. The search optimization process doesn’t care.
We pick domain names because we like them because we believe in them because we trust them. There is no SEO reason to use domain name ALPHA over domain name GAMMA.
So changing a domain name, or adding a subdomain, these actions don’t really affect your SEO. These are business decisions and your SEO supports them. That is no fine and subtle distinction — it’s an axiom. It just does not get any simpler than that.”

QUOTE: “How do I move from one domain to another domain and try to preserve the rankings as best as possible?…do a 301 permanent redirect to the new location.” Matt Cutts, Google
Many years ago, the domain name was having a massive impact on the rankings of the website. However, now Google has modified their core algorithm to reflect an abuse of exact match keyword domain names.
The approach to SEO has certainly changed, but the goal is still the same. Websites should be able to provide quality contents to visitors. But the fact is that domains do not hold the same power they once had. The ranking of the website now does not depend on the keywords of the domain
I conclude that what William Shakespeare said is true.what is special about a name, NOTHING. But of course, the value lies in Brand name.So the domain name should be relevant to your business, does not matter if it has keywords or not, It will look into the contents, relevant to business.
