Some many extensions, which one is the best?

A. There is no best extension. Try to get the extension that fits your domain best and if available also get the .com. Some more popular extensions are .com, .net, .us, and .info. There are many country code extensions. Recently there have been a lot of new extensions being released. Some domain registration companies give out free domains for for new extensions to gain interest in them. When it comes to domain extensions .com is the most popular and most known. Followed by the .com are .net, .us, .info, and country code extensions. For example: game.com is worth more than game.info, or cash.net is worth more than cash.tv. Some newer extensions are pretty much worthless due to lack of interest unless you have a top keyword. Make sure to do your research.
