Some websites make it easy to shorten URLs and track how many people clicked on those shortened URL links. Using a URL shortener takes just a few seconds. Simply copy the URL that you want to shorten and paste it into the appropriate text box on the URL shortener website that you choose. Click a button, and a shortened URL is provided to you, which could be as few as ten characters in length.
URL shorteners offer another benefit to webmasters, authors or bloggers. Sometimes URLs change. If a URL that you share via Twitter changes, the URL you publish in your tweet won't work. Using a URL shortener often fixes that problem. After you create a shortened URL, it should always lead people who click it to your original linked page.
URL shortening is a technique on the World Wide Web in which a Uniform Resource Locator (URL) may be made substantially shorter and still direct to the required page. This is achieved by using a redirect which links to the web page that has a long URL.
Often the redirect domain name is shorter than the original one. A friendly URL may be desired for messaging technologies that limit the number of characters in a message (for example SMS), for reducing the amount of typing required if the reader is copying a URL from a print source, for making it easier for a person to remember, or for the intention of a permalink.
Other uses of URL shortening are to "beautify" a link, track clicks, or disguise the underlying address. Although disguising of the underlying address may be desired for legitimate business or personal reasons, it is open to abuse. Some URL shortening service providers have found themselves on spam blacklists, because of the use of their redirect services by sites trying to bypass those very same blacklists. Some websites prevent short, redirected URLs from being posted.
