Acos went from 34% to 100%

Hi, Has anyone else had their main keywords Acos skyrocket? I was getting 34% Acos for the same campaign August-October, and steadily in November it’s tripled. I just spoke with Amazon and they say there’s nothing they can do. I’m just trading money now.

Naturally with the amount of traffic coming in on these dates, you’re going to see a high number of clicks but a lower conversion rate.

Black friday was great for me at an ACOS of 20%.
The key is to do KW research everyday and make sure you’re campaigns are filled with KWs that convert consistently.
