Amazon Ads Are Getting Traffic, But Shoppers Aren't Clicking – Need Help Fixing It

I sell products with several variations, and lately I've been dealing with two completely different problems. Some campaigns barely get impressions, while others get plenty of visibility but people just aren't clicking. It's frustrating because I'm spending time and money without understanding where the disconnect is. I don't necessarily need someone to rebuild everything from scratch. I'd rather work with someone who can look at what's already there and explain: - Why some campaigns aren't getting traffic - Why others aren't converting impressions into clicks - Whether variation setup is affecting performance - If the listings themselves are hurting CTR - What should be fixed first If you've worked with variation-heavy products and understand Amazon PPC beyond simply raising bids, I'd love to hear your thoughts.
