A URL shortener is an easy tool that reduces the character length of a long URL by creating a much shorter one. This shortened URL redirects back to the original URL.
Other names for a URL shortener are link shrinker, link shortener, small link maker, and URL condenser. All of them refer to the same thing. The main purpose is to save characters and to make your links “look better” and easier to share and manage.
People use URL shortening services all the time, especially on social media platforms. When Twitter hit the scene, the character limit for Tweets was only 140 characters. This was problematic when people wanted to share a long link to a web page. The link could easily eat up ¾ of Twitter’s character limit. This problem could be solved with a URL shortener.
URL shorteners also allow users to mask their web addresses. Affiliate marketers like this capability so they don’t have to show their Affiliate ID in their marketing campaigns.
