If you’ve enabled the “auction time bidding” setting of SA360 the bid strategies are effectively the same as google ads bid strategies. They use the same algorithm and signals as google ads, but would be using your floodlight conversion data from SA360. If you don’t have “auction time bidding” enabled the SA360 bid strategies function as intra-day bidding in SA360.
If you’re paying for SA360 I’d recommend using one of the Auction Time Bidding strategies with your floodlight data. You’ll get the benefit of the google ads algorithms and true auction level bidding plus the additional feature set of SA360 layered on top including things like cross account portfolios. Let me know if you have any other questions!
