    Bitly Review - Amazing Experience.

    Bitly is a URL shortening service and a link management platform. The company Bitly, Inc., was established in 2008. It is privately held and based in New York City. Bitly shortens 600 million links per month, for social networking, SMS, and email. Bitly makes money by charging for access to aggregate data created because of many people using the shortened URLs.

    The Bitly URL shortening service became popular on Twitter after it became the default URL shortening service on the website on May 6, 2009. It was subsequently replaced by Twitter's own t.co service.

    The company uses HTTP 301 redirects for its links. The shortcuts are intended to be permanent and cannot be changed once they are created. URLs that are shortened with the bitly service use the bit.ly domain or any other generic domain that the service offers.
