Spaces in the media code are not recommended. It is better to use an underscore "_".

Special characters should be omitted. Media codes that contain an asterisk * will not be tracked, a plus "+" could be interpreted as space, etc.

The following characters are always removed:

  • <
  • >
  • "
  • '
  • \

In addition, we recommend writing the media codes completely in small letters, as this is less prone to error. The background is that Mapp Intelligence is always case-sensitive. So if a media code with uppercase letters has been deposited in the automatic advertising media recording and somebody accidentally writes everything in lowercase letters, then this advertising material would not be tracked by Mapp Intelligence.

Furthermore, there are also general conditions for characters in a URL: , section 2.2.

We also recommend creating a fallback channel.
