@Austin LeClear maan, thank you so much for taking the time! You have no idea how much I appreciate it! Yeah, it was really helpful :) Actually I've implemented this into an account with a lot of data in it already, and although it's been less than a week I'm seeing something interesting: Top sellers campaign: I put 5 categories (maybe too many?) Mid/Low Campaign: 4 categories + an asset group with all the rest of the categories (so it's a very general one) But here's the interesting thing: the general asset group works better than everything. It even outperforms the Top Campaign by a lot: 14-17 May, same budget, for both campaigns: - Top Campaign: 7 conversions - 2.95 ROAS - Mid Campaign: 20 conversions - 19.97 ROAS (all sales from the general asset group) Have you seen something like that happen to you? where actually not segmenting works better?
