Google Shopping ROAS bidding
Seems to be working reasonably well in most cases so far…
Here’s one example :-
This is a campaign that is somewhat seasonal, and it would usually make more sense to compare to ‘previous year’ rather than ‘previous period’, but I couldn’t in this particular case. At any rate it is still a bigger improvement than another shopping campaign in this account that has using enhanced CPC bidding during the same periods.
