When you buy a piece of real estate, you make arrangements to pay for it, and you become the owner. You are the owner until you decide to sell it. In the online realm, your domain is your virtual estate, identified by the exact wording of the name. For example, on domains.com, godaddy.com, bluehost.com, wealthy affiliates.com and other sites the words matter and so does the suffix.
cleanwater.com
ourcleanwater.com
cleanwater.net
cleanwater.org
....are all different domain names
The question is always "Do I have the right name?". The answer comes with careful thought about the intention of buying a name, and the possible scope of your business. You never want to buy a name that is too narrow, should you decide to expand.
Now that you have decided on and purchased a name, with or without privacy settings, is that all you need to know about domain names ?
No .You are not done yet.
I tried the sites you mentioned but struggled to find a valuation section in all but one of them.
Will send you a PM on the off chance you can help. If not - no problem.
Cheers
