Tracking 404 Pages

You can not tell if a page did load or showed 404 just by viewing the visited pages list.

You might want to know if users land on a page that renders your 404 content.

To get better insights, we can:

1. Create a 404 Tag, so we can easily filter those sessions.

2. Create a 404 Event, so we can see which page triggered the 404 error.

Include this JavaScript snippet in your 404 page template.

File: 404.html

<!-- After the tracker is included -->
<script>
UST.addTag('404-page-not-found');
UST.addEvent({
    category: 'ERROR',
    action: '404_NOT_FOUND',
});
</script>

The end result will be something like this:
