A short URL link to a page on the web is definitely easier to share with people rather than very long URLs. For eg., The URL to our Netbook Buying Guide is http://digitizor.com/2009/02/21/digitizors-netbook-buying-guide-10-things-to-consider-before-buy-one/ but the same article can also be accessed using the short URL – http://bit.ly/BlUO9 and this short URL is definitely easier to share with others. This is what URL Shortening services do. You give them a URL they give you a much shorter and stripped down URL.
Techcrunch has released some interesting statistics about URL Shortening services like tinyurl.com, is.gd and, bit.ly with Tinyurl holding 3/4ths of the market share of URL shortening services. According to some math by Techcrunch, bit.ly has a $8 million pre-money valuation ($10 million post-money). Its market share of shortened links, as calculated by Tweetmeme, is only 13 percent. And by the same math, Tinyurl’s valuation was found out to be at least $46 million. So it is high time you start your own URL shortening service and see yourself earning millions in no time. via [Techcrunch]
