There is a lot of debate over whether the singular of a domain name is preferable to the plural. The answer is – it depends! Depends on the word, depends on the context.
Speaking specifically about a couple of our domains, we believe that our bonusdeals.com and krazydeals.com are best in their plural form. They then refer to more than one. As well, this is the proper usage of these two “deals” terms. No one would enter a store and say “I want bonus deal,” he would say, “I want bonus deals!” Absolutely! Don’t sell yourself short, don’t be limited. In many cases, plural all the way!
