A lot of people got in touch with us in the past and asked: What is actually the difference between having “bit.ly” and “j.mp” links when Tweeting? The short answer to this question:
None, they are both the same.
Both shorteners are coming from the link shortening service Bit.ly. So if you want to track your links with the service Bit.ly it doesn’t make any difference if you are using j.mp or bit.ly.
The only difference is that links with “j.mp” are 2 characters shorter than “bit.ly” as you can obviously see. So if you are giving the option to squeeze 2 more characters in from using j.mp.
That’s all really, I hope it helps as a quick clarification. So if you are a Buffer user, you can now choose between bit.ly and j.mp. Both analytics results from Buffer are delivered from Bit.ly and whichever shortener (j.mp or bit.ly) you pick, the results are the same.
