The best reason to use a URL shortener  is s that you have access to the data on what people do when they see your click. If you post a regular, cut and pasted URL you won’t be able to track real-time engagement with it or clicks, but when you shorten a URL you’ll be able to track click-through rates and even track where they are clicking from.

For example, if 80 people click on a URL in a funny post promoting your blog post but only 20 people click on a URL in a more serious post, this knowledge can be applied to future posts. In other words, URL click data can be used to increase the chances of your followers clicking a link.
