Clickbooth allows third party pixel tracking on over 90% of our campaigns. The ability to place pixels will depend on the Advertiser's technical system. To find out if a specific campaign allows for third party pixel placement, click on the campaign link and in the basic info tab you'll be able to view whether or not pixels can be placed.
At Clickbooth, we provide publishers the option to upload image, frame, and script pixels directly through the publisher interface. On the campaign details page, click on the Testing and Tracking tab and paste your pixel directly into the form, and click, "Save"
