Google restricts TrueView video ad rotation settings to “Optimize for views” only

Optimize for conversions and Rotate evenly options are no longer supported for TrueView ads. If you’re running video campaigns on Google properties and have set ad rotations to Optimize for conversions or to Rotate evenly, you’ll want to take note that Google will be switching your rotation setting to Optimize for views — if it hasn’t already. Advertisers are seeing a notice in AdWords that Optimize for views is now the only ad rotation setting available for video campaigns and that all campaigns will be automatically changed to that setting in January.
