Are Amazon Ads Worth It For KDP ?

Hello everyone, I'm new to this group but I've been on KDP since 2020. Here's my Amazon ADS performance of all time (good but not the best I know). My strategy was always low budget low ACOS but I'm changing it in the last few months that's what explains the ACOS that's going up and I'm aiming for long time results. If you have any questions about Amazon Ads feel free to ask.
