The metarefresh function is used to prevent the referrer URL's of your traffic from being forwarded to your destination URL's / offer links. It is commonly used to prevent affiliate networks or advertisers to see where you buy your traffic.
By default, TrackingDesk hides the referrer URL's, thus showing the affiliate network only a one of TrackingDesk tracking internal domains.
How to verify that the referrer URL's are not passing.
- Create a campaign in which the offer link is a web-site where you have an analytics software script installed i.e. Google Analytics
- Add the campaign URL on a web-site and click the URL.
- Go to your Google Analytics dashboard and check your referrer stats.
