Advanced Setup: Not Found Page Title

The GTM Variable “RegExp Title Page not found” must contain a text that is part of the Not Found page title. You will find the Variable in the “WAS – Setup” folder.

The default value is “404|page not found”.


  • In regular expressions the character “|” works as “OR“.
  • “404” is the error code which is part of the page title very often does not matter the language.

Typically, if you page title is in other language than English, you must change the value.

E.g., for Spanish Amazon it should be “Documento no encontrado”.
