The URLs of your pages are available in the "Event URL" property.
By default, this property is fed with the information transmitted in the request's header. This information is dependent on the browsers, and in particular on the Referrer-Policy in place. Based on the configurations, it is possible that only the global domain is transmitted, making the URLs available in the tool imprecise.
- From Tag Composer, edit your site configuration to add the advanced options: "Querystring added to the property containing the URl of the page" AND "Automatic detection of a property containing the URL of the page".
Note: these options are available from version 5.27 of Smarttag. If you do not see them, you will need to update the library first.
