RedTrack allows you to send your traffic directly to your landing pages or own offers without using any redirect link while still tracking everything.

Each Сampaign generates both links - Campaign Click URL (redirect link) and Direct traffic script:
If you want to see the Direct traffic script on a Campaign level, just switch it on in your Traffic Source settings:
The no-redirect script is tied to the precise campaign by the Campaign ID. It means no-redirect tracking option does not allow to use the same Lander for different Campaigns when the no-redirect script has already added to the Landing page code.
