I do about $60K a month on Amazon. Last month I spent just shy of $8K on sponsored ads, with a 3.55 ROAS. I hired a freelancer work on refining my ads for me. I'm considering stepping it up and having an agency do the same. They're more expensive, but I'm hoping they can help me get to that next level.
I'm wondering what others experience is with professional management of Amazon Ads. Did they outperform your own efforts? Did you find it worth it?
