We all know .com — the most popular domain on the internet. A .com.ru domain is the same thing, but localized with .ru, the country domain for Russia. If your business wants to have a presence in Russia, then a .com.ru domain is a perfect fit. Not only do you get the internationally known .com, but the local addition of .ru. Is .com.ru the perfect domain for you? Maybe. You'll have to make that call yourself.
