What is it?
Thanks to Performance MAX insights, you can see more information about the performance of the PMAX campaign. For example, you can see where the campaign is showing and how it's doing there. So if you see that the campaign is not doing well in Google purchases, you can decide whether to edit the campaign or perhaps make a new one.
You can also see which assets are performing well and which are not. Thanks to this, you can, for example, change the text of the ad, or add images that didn't perform well and see if the performance will improve.
Where is it located?
