Click tracking is not visible to visitors since the entire process takes up around 6 milliseconds making it invisible to the naked eye.
Your customers will not notice the redirect to your landing page that happens after tracking is completed. A tech-savvy visitor who is monitoring web traffic will be able to register both ClickGUARD’s and Google’s own tracking, by using software. However this is not the behavior of a vast majority of Internet users.
With parallel tracking in Google Ads ClickGUARD's tracking is not visible even to machines.
