- Referrer URL limitations

CODE Marketing cloud uses a referrer URL (document.referrer) in the following functions.

• Targeting via “Traffic source type”
• Targeting via “Referrer URL”
• Start trigger with a “Not displayed when moving within the same domain” option when “Return” is selected

However, there are the following restrictions for obtaining the referrer URL in each OS, browser, site and source communication protocols.

• According to our original research. Note that there may be some differences according to OS and browser versions.

For end users in an environment where it is not possible to obtain the referrer URL, web customer service operates in the following way on CODE Marketing cloud.

• For campaigns implemented using “Traffic source type” targeting
  • The traffic source type is identified as “Direct traffic” and operates as such. (See Traffic source type identification rules)
• For campaigns implemented using “Referrer URL” targeting
  • Because the referrer URL cannot be obtained, it is not a match for targeting.
• For creatives that use a start trigger with a “Not displayed when moving within the same domain” option when “Return” is selected
• When the referrer URL cannot be obtained, that creative will not be displayed.
