Stock out of inventory for extended period. One of a kind item. Poor Ad Performance.

Hi All!

I have a business based off of a card game that I made. It’s brand registered so i’m the only listing on amazon. I went out of stock back in December of last year but due to a myriad of reasons I just recently got back in stock. My previously successful Amazon ads aren’t working like they used to. I’ve been tweaking the ads but my ad spend far exceeds my conversions.

I want to know what happens to a seller account when you have an extended absence? How can I fix my ranking or how can I hurry and get back on track.

What other general advice do you have for me?
