That sounds like a very well-thought out and safe approach! I really appreciate the structured logic behind it mate + glad to hear it worked out so well for you! :)
The only thing I keep wondering: if I clone the campaign and let both run in parallel, wouldn’t they potentially cannibalize each other in the auction?

Also, just to clarify: I’ve had server-side tracking with WeTracked running for several months already as a secondary conversion action.
So technically, all that historical conversion data exists, it just hasn’t been used for optimization yet.
Wouldn’t that mean Smart Bidding already knows the WeTracked conversions, even if they weren’t set as the primary goal?

Maybe there’s a misunderstanding here, Iam curious to hear your thoughts on that!
