Optimize Amazon Campaign for Sales

My Amazon PPC has reached a plateau and I need a sharp optimisation to push unit sales noticeably higher. The priority is clear—Increase sales—so every tweak you make should move the needle on conversion rate and daily revenue. Here is what I expect: • Inside Seller Central: restructure or create Sponsored Products and Sponsored Brands campaigns, refine keyword targeting, adjust bids, and refresh ad copy where needed. • Tracking & proof: set up clear metrics (ACoS, TACoS, ROAS) and provide a concise before-and-after report explaining each change and the results it drives. I’ll supply full access to campaign history, search term reports, ASINs, and any creative assets you require. Please share examples of past Amazon Ads wins, the tools you rely on—Campaign Manager, Bulk Sheets, Helium 10, PPC Ninja, or similar—and your typical timeline for showing traction. Let’s turn this spend into measurable sales growth.
