Is the ROAS bid strategy not applicable to shopping campaigns? I can´t make it work in the accounts I´ve tested, the system just won´t let me apply it, saying I can´t apply it to that campaign. The campaign has over 100 conversions last 30 days.
This help file seems to suggest it is possible... https://support.google.com/ds/answer/6047252?hl=en
Or is it only applicable for product groups, not as a campaign config and not for ad groups??
Re: roas shopping
As conversion optimizer is not supported with Shopping Campaigns, ROAS too isn't supported.
The article you have referred is for DoubleClick by the way, it might work differently. Never tested it with DoubleClick.
Hope it helps.
