There can be a few reasons for this:
1) Make sure that you are not testing the page visit while logged into Mautic. Mautic ignores user generated activity so use an anonymous session, another browser, or logout of Mautic.
2) At this time, point actions are tracked once per contact. This means that subsequent visits will not re-trigger the action if already triggered once.
3) Ensure that the URL defined either matches exactly the URL visited or use a wildcard (note that the URL can include the schema, host/domain, path, query parameters, and/or fragment).
For example, if you have a URL of
http://domain.com and the page hit registers as
http://domain.com/index.php?foo=bar, the action will not be recognized. However, if you use
http://domain.com* as the URL, it'll match and thus trigger.
