The thing I didn't expect to care about this much is that it never touches the account without me saying yes. It shows up with a short list of proposed changes, I approve or skip, and everything gets logged with a before and after. When one batch pushed a couple of placement modifiers way harder than I liked, I could see exactly what changed and roll it back the same day. On the ads side it found where the spend was going sideways. Product-page placements were eating budget with almost nothing to show for it, and a pile of old campaigns on hats, mugs and gift boxes were running at ACoS numbers that made no sense. It flagged all of it, I paused the tail stuff and moved budget toward top of search, which was converting at roughly double our other placements. It also throttles spend on keywords where we already rank near the top so we're not paying to show up where we already show up. Images are the other big one. Instead of a redesign that swaps seven pictures at once, it tests one thing at a time, like a different headline callout on the main image or a couple of new secondary images, and it keeps the old set so I can go back. That's the first time I've felt comfortable testing images on a listing that's actually selling. Somewhere in the middle of all that our main Cloud Socks listing picked up the Best Seller badge in its subcategory. Conversion went up, organic orders jumped, and that let us ease off the ad spend a bit instead of chasing rank forever. I won't pretend one tool did that alone, but the cleanup and the image work were clearly part of why it happened. Review collected by and hosted on G2.com.
It's still a young product. Some of the newer features feel experimental and the UI doesn't always make it obvious what state a test is in (queued, live, measured). I've had a few image tests that didn't confirm cleanly on Amazon's side and needed a manual check. It also doesn't cover everything yet, so I still go into Seller Central for backend keywords and inventory. And it is strict about not acting on its own, which I like, but it does mean you have to actually show up and approve things or nothing happens. Review collected by and hosted on G2.com.
