Hello, I have a question and need a recommendation. I have an online shoe store and have been running my entire shopping feed for a long time. This means that in the shopping feed there are 16 examples of each shoe in each size. That's why I have a feed with 4000 products in it. I'm just about to rebuild my PMax after watching your video. Thanks for the valuable information.
My question is now is it more useful if I select my best selling shoes and then add only 1 size of these to the PMax so that I only have about 15 products in the feed or should I take all sizes in the feed which means that I have 240 products in the feed.
