In order to avoid confusion with tracking, for example, zero tracks or for the loss of some tracks, we recommend using the following simple rules below:
1. Please use WD _wd_t tracking or utm_source Google tags. You can learn more about this in the special section of the WD user manual.
2. It is recommended (but not required) to use English letters and no Roman Numerals for tracking.
3. We recommend using tracks that do not exceed 255 characters.
