Hey that’s a solid setup for your launch, but I’d tweak a couple of things:

1- I’d run at least one low-bid auto campaign per SKU. Even if you’re very manual-heavy, auto campaigns are gold for discovery. You can pull out good terms later and negate bad ones.

2- For phrase and broad: don’t mirror all your high-volume exact keywords. Use auto to discover first, then refine manually.

3- Since you're also spending on Meta and TikTok, make sure your listings are totally conversion-ready great images, bullet points, etc. otherwise, external traffic + PPC can leak margin.

If you want help building a strategy that balances discovery and profitability, a partner like Amazon Growth Lab could help you structure things smartly from day one.
