Can anyone explain why our featured offer % is 43%, when each of our Active products is "√ featured offer" on the inventory page, pricing health says: "Show 0 offers not eligible to be the Featured Offer", and a spot check of products shows us with the Buy Box on every one? Account health is perfect, and we're sole sellers of our branded products, which account for +/- 98% of our inventory on any given day.
We've been seeing this behavior for years ... individual products retain the buy box, but our buy box % is all over the map. I can clearly correlate actual sales with this rate, though. When this number drops, sales dry up, and when it gets near 100%, our sales are excellent. It feels more like a measure of whether our products are being surfaced than whether they're being bought. Is it possible that you can "have the buy box" but that certain classes of customers do not see that (and instead see the message that, basically, "this seller sux").
