A domain name helps a lot in online marketing. But .com or .net domains are costly. You can’t afford to register 100 .com or .net doamins. Also most of the short domain names are already registered and hence not avaialble for registration. Some nice .info doamins are still available but .info domains are no less costly than .com or .net. Also if you don’t have an way to spend money online then registering a paid doamin is not possible for you.
Fortunately you have a good option to register free domain names. Obviously this is not .com or .net doamin. I am talking about free dot tk domains. Dot Tk allows to register unlimited domain names for completely free. Your web page will be shon in a Frame. No ad is shown.
