Exactly this.
I have particularly noticed lately a high incidence of seeing items from brands I have recently purchased from–even if it’s not the brand I have most often purchased for that/similar item, and without my giving product reviews or Seller feedback.
Now, I am me, and I finagle my shopping searches to workaround Amazon prioritizing those brands, but I was still wondering why the heck Amazon thinks I’m all in on some rando brand I bought once (maybe on a deal) versus the brands I have bought from consistently over the years.
And it’s right there in About You: “Brands”.
When you click, you get brands (with arrows to orders) that AI thinks you “choose,” “select,” “prefer,” or “favor.” But…no. Buying a single product one time is not a meaningful data point and should not now be gumming up searches based on my so-called “preferences”.
But that’s what we’re up against now as Sellers: Amazon limiting Buyers’ views of (allegedly) non-preferred brands in search and featured screen time based on very faulty AI extrapolation.
