bitly.pro
I just spent a few minutes signing up for bitly.pro. It’s an easy way to create short urls specific to your domain of choice. After way too much consideration & deliberation I registered twa.lt and tied it to my pro account. If you’re having trouble deciding what to register, be sure to check out this list of possible domain extensions. From there, you’ll have some minor DNS changes to make via bit.ly’s setting panel before you’re off to the races. Happy linking!
