RADAAR has a built-in URL Shortener. If you have any URL in your content RADAAR automatically shorten it before publishing. So when your content is published, your URL will look more pleasing to the eye.
If you want, you can disable this feature by turning 'Shorten all URLs' option off. You can turn this option off while preparing your content. If the color of this option is green, it means on, and if it is white, it means off.
RADAAR remembers your last choice. So you only need to disable it once.
