My website is running a lot of test pages for specific purposes. Problem is I don't want to count these session and page views in Google Analytics, because we will have lots of false traffic. So I need to block these traffic data in Google Analytics.
Notice 1: Exclude IP filter won't work. We use VPN for these test pages. We also test it anywhere.
Notice 2: Custom Reports or Segment or anything are not recommended here. I know how to do this but don't want to do.
Notice 3: Website is Wordpress but I can't access to edit htaccess or to remove GA analytics.js.
Notice 4: I am able to use Google Tag Manager. Any Tag Manager tips are welcomed.
Thank you.
