Ad Server Advertiser

YouTube only certifies the following platforms: Desktop, Mobile Web, and Mobile App. We will investigate discrepancies for certified platforms only. For uncertified platforms, Google will have no liability for a discrepancy between Google's impression and click counts and those of the third-party. YouTube does not offer credits if reporting discrepancies occur with research vendors. Credits and/or make-goods are never offered for research studies other than Standard Ad Serving Vendors providing a 3rd-party impression-tracking pixel.

All vendors must complete a certification process. At its sole discretion, Google reserves the right to change this vendor list at any time.
