Limitations of less common website suffixes like .biz, .us, or .info
Common people expect you to have .COM domain, and also there is a saying “ if .COM domain is not available then probably name is trade mark” , genuine buyers avoid domain names with trade mark associated with it. For example think about registering MICROSOFT.BIZ and doing business with it….
If the name you choose is not registered as an intellectual property of others, you can use any names .info or .biz, remember many of them try your website initially with .com then realize and use the actual.
Country specific names will still have a chance in every country .co.uk, .ae, .in or .qa have better scope than using a .biz
