Changing ad/adset in FB

[AltGR]

Hey Tim,

Thank you for doing this.

Facebook collects data for optimization depending on the campaign or optimization objective.
I heard that it is gone if changes are made.
Is this true on an ad level? changing copy, picture headline makes it pretty reasonable, but how about changing the link?
On adset level, does it influence the facebook history if I change the targeting? or add placements etc?

It isnt fully gone when a change is made and it depends on the change. And yes basically no matter what you change there is going to be a new "test" facebooks algo will run. The algo does take into account though ads and adsets lifetime history that you have had with the same or similar headline, your URL, the image, your targeting etc.
