It's incredibly easy to create shortened links. Among business owners, it's a well-known and respected link shortener (even though it does so much more than that), so even if you don't have a custom domain, it's not frowned upon if you're using a bit.ly link instead of your own. The free version does that for you, but there are paid options for more analytics. Review collected by and hosted on G2.com.

The pricing is a bit high if all you're looking for is link shortening, which is my intended use case. I don't want to have to pay for a bunch of other unrelated (to me) services. There should be a cheaper middle-ground option. Review collected by and hosted on G2.com.
