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.
Under campaign settings for video campaigns, Optimize for conversions and Rotate evenly options are listed as no longer supported.
Google actually started making the switch this month, as noted on the AdWords support page about ad rotation settings: Note: To simplify ad serving and campaign management, ad rotation settings will no longer be available for video campaigns starting in December 2016. Instead, all video campaigns will be optimized for views by default.
The change is significant for performance advertisers that run video campaigns with a goal of generating conversion actions, not just views, and those who have been using Rotate evenly for A/B testing ads for outcomes other than views.
A video view is counted when a user watches 30 seconds of a video ad — or the full video if it’s shorter than 30 seconds — or engages with a video ad in some way.
