I need to get my head straight. I know my category keywords, but I'm confused about how to set up campaigns, assign budgets, track data, and optimize based on performance.

I see competitors running two campaigns for the same keyword – why? I also see people using "down only" bidding but no clear explanation of why.

I want a detailed, practical guide – not fluff or paid courses. I'm happy to pay for real value.

Here's my situation:

  • We do private label, mostly non‑standard products, some standard ones. Price range $10‑40.

  • We've launched 10 products, all successful (top 10k main category, two BSRs, all profitable). But I feel our ad efficiency is poor – high ad cost, thin margins. Some products could be BSR but aren't.

  • I want to run a product myself to see if the issue is product development or advertising.

Looking for:

  1. Which campaigns to open when a new product launches (auto? manual exact? broad? phrase? product targeting? SB? SD?)

  2. How to set initial budgets (concrete numbers or formulas)

  3. What data to track daily/weekly (spreadsheet templates welcome)

  4. How to optimize based on that data (when to raise/lower bids, pause, add negatives, adjust placement multipliers)

  5. Any AI ad tools worth trying (and which ones are overhyped)

Thanks in advance.
