With Brax, you can set up your tracking once and apply it by default when you create new campaigns and ad groups.
To start, click on your username, then click tracking.
You'll see all your connected sources on this page. Click on any of the lines to show all supported macros for that network.
*Remember that Yahoo Gemini Campaign Tracking is entered at the Ad Level
When you're finished, hit save. Brax will apply your tags to all new Campaigns and Ads moving forward. Keep in mind they will not be retroactively added to existing campaigns and ads!
