If you have given a chance to buy domain name, which extension will you like to buy?

The priority must be given to .com, .net, .org, .info, .biz. You must understand the value of each extension. Most of the company or blog will tend to misuse the .com extension. Previously the .com extension can be used only to company but since the value is supe high if compared to the other extension, people likes to buy the .com and develop it.

I made mistakes of buying the .biz extension while I know that .com value is high. My website on .biz extension received around 3,000 to 5,000 unique visitors monthly but no resale value because of the domain on .biz extension.

So please make sure that you buy the .com extension rather than .net or .biz
