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 service.

The company behind bitly launched a similar service, but for online videos, to determine what videos are the most popular on the web.

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 domain or any other generic domain that the service offers.

The company offers a paid solution called Bitly Enterprise that provides advanced branding features. Companies can use their own custom domains to generate shortened links; for example, The New York Times uses, and Pepsi uses This allows the company to push brand awareness on services such as Twitter but use the bitly engine to generate the shortened URLs and track marketing metrics. Bitly Enterprise also has advanced analytics features and uses bitly data to provide advanced social insight tools for companies and brands.
