Google Analytics Blocker Detection

Learn how Umbraco Engage handles visitors who use blocker detection.

When a visitor runs an Adblocker or cookieblocker the visitor is likely not tracked in Google Analytics. With Umbraco Engage you can still track this visitor.

This is made possible by a JavaScript file that you can include before the closing body-tag in your HTML:

<script src="/Assets/Umbraco.Engage/Scripts/umbracoEngage.analytics.blockerdetection.js"></script>

The following Google Analytics blocker detection script loading types are currently not supported: "async" or "defer".

If you include the script one of the following events is sent:

• If Google Analytics is blocked in the browser of the visitor: umbEngage("send", "event", "Tracking", "Blocked", "Google Analytics");

• Otherwise, the following event is sent: umbEngage("send", "event", "Tracking", "Allowed", "Google Analytics");

To see the statistics of this event go to the Analytics section of Umbraco Engage and open the 'Events' report. Look for the category with the name 'Tracking'.
