The dashboard can be weird. I spent some time today changing bids on keywords, and several times I suddenly was back at a different page. At least the changes I made held.
As to why I made these changes, it's very simple: Amazon hasn't been spending my ad budget. It spent only $1.50 yesterday. That's pathetic, with nonexistent sales and page reads to match. It's certainly proof that one must advertise to get any attention on Amazon.
So I reactivated a ton of keywords, added more, hiked all the apparently nonperforming bids, added another negative keyword, and upped the daily ad budget. This is on my series opener that has sold steadily for four years and for nearly three years with this ad. I don't really want to change the ad itself or do a new one; that involves a lot of pain in copywriting. Some aspects of marketing just never get easier.
