Since 2010, Twitter discreetly shortens all shared links using their own t.co short URL service. So if you tweet a link that is 100 characters long, Twitter only counts 20-23 against your 140 characters, which is great. Sharing links on Twitter has been easier in recent years than it used to be.
Last week we finally disabled AddToAny’s default link shortening to Twitter using Bitly’s j.mp service. Bitly had a good run on AddToAny’s platform since 2009, and Bitly will remain as a URL shortening & link tracking option for publishers.
