These things are Flippin awesome. You can practically have your own domain name. My favorite is GG.GG. It’s best if you created an account. This way you can take a long URL pasted in click the button that says customize then make up your own name then hit enter. Now you got what used to be a 46 million strand URL turned into GG got GG/whatever you decide.
And if you’d like your shortened URL but you want to change the actual long URL to something different you just go into your links section and make the changes I am. It’s a done deal and that’s my two cents peace! out, cub scout. lol
