A URL shortener is a tool that can take a long, complicated URL and turn it into a shorter, simpler one. It’s useful when sharing links on social media or in situations where URL space is limited.
URL shorteners work by assigning a unique code to each long URL. When someone clicks on a shortened link, the URL shortener service redirects them to the original, long URL.
Marketers also use URL shorteners to track how many people click on a particular link.
There are many different URL shorteners, but Bitly is the most popular.
