The Smart List in a Campaign gives 'Invalid URL' error for a valid URL (non-Marketo landing page URL).
To make sure non-Marketo landing page URL will show up in Smart List's filters, the following steps have to be done.
- Make sure the Marketo Munchkin Tracking code is implemented and placed within the non-Marketo webpages.
- The non-Marketo URLs would show in the filter if a known lead/person has visited the web page and tracked into the activity log. Therefore, make a lead/person and visit the webpage to allow Marketo to track and log that URL visit.
