I was considering eventually using it for a short domains sales site.
There are very few domain sale domains available --.
.
Is it just me, but I was under the impression that half the people here at some time have listed a domain name for sale with "I was thinking of using it as a domain name site," or, "it would make a great domain name site."
There may be very few good KEYWORD names left such as DomainNamesForSale.com. I might have missed something, but how is ShortBrands good for domain names except maybe for branding. Do many of your potential customers really search for "short brands" or "short brand names." Nice, "Short Brands" logo by the way.
If you are trying to do SEO on a popular term like "domain names" or "domain names" for sales, the big firms own the first few pages. I have tired, not too hard, but my site
www.seemly.com is about on the 10th PAGE (100th result) on the google search term "domain names." I have done better, like first or second page, on secondary search terms such as "domain name ideas."
See the previous appraisal threard titled "someone offered me $70" for many suggestions on what is a minimum prices for any domain name. Most people suggest asking for more than low $xxx and maybe settle for low $xxx.
