If you are generating a QR Code, most of the times you want to redirect the user to a website, e.g.:
http://www.youtube.com/watch?v=D1R-jKKp3NA. This URL is called the target URL.
If you create a dynamic QR Code, the target URL is shortened by default to a random URL e.g.
http://qrd.by/0j6nte. This is called a shortened URL. With qrd°by you are able to customize such a shortened URL. Instead of
0j6nte you can set a human readable name e.g.
speech-steve-jobs. Such URLs are called custom shortened URLs or Vanity URLs.
What is the benefit of a custom shortened URL?
People who are scanning your QR Code will now see
https://qrd.by/speech-steve-jobs when the QR Code is decoded in the scanning app. This will give them a better idea of where the QR Code leads them to. Moreover a shortened URL encoded in a QR Code allows printing the QR Code in a smaller size, since fewer characters are encoded in the QR Code (See also Minimum size of a QR Code). Using shortened URLs also allow you to track who is scanning your QR Codes. So you can measure how succesful a QR Code campaign is performing. Read more about tracking QR Codes.
Custom shortened URL + Custom Domain
With the White Label QR Code Manager you can even set a custom domain for a dynamic QR Code. For example instead of
qrd.by you may use the custom domain
my.domain. The QR Code will then have the custom URL
http://my.domain/speech-steve-jobs encoded. With a custom domain you can keep your brand and your corporate identity without exposing that you are using our QR Code platform.
