I'm thinking of trying something in terms of helping the fb algo quickly learn how new audiences work.
When seasoning a pixel, can you change the pixel being optimised for in the same campaign - or do you create a new campaign and change the pixel that way? This is using CBO by the way.
I.e)
Directly change the pixel even in each adSet that meets optimisation rules.
Campaign 1: Targeting VC Pixel (When optimised (50+ events) -> edit the Adset and rotate the pixel to Add To Cart (Wait for 25-50 events) -> edit again and rotate to Initiate Checkout Pixel for 25 events -> finally rotate to Purchase pixel?
Or
Duplicate at campaign level and rotate the pixel event
Campaign 1: Target VC Pixel (wait for optimisation) then duplicate:
Campaign 1 (Duplicated): Now targeting Add to Cart - wait for optimisation and duplicate
Campaign 1 (Add to Cart Duplicated) - etc. etc.
OR
Duplicate the AdSet and in the new AdSet change pixel event, keeping it all within the same campaign.
Campaign 1: Adset 1 Target VC Event (wait for optimisation), then duplicate AdSet 1 within the campaign and rotate the pixel to Add to Cart etc. etc.
