And I found Rick's BKLINK tool to be great for finding out what categories Amazon has stuffed my books into. It would take a lot of hours of checking each book section for your book, and BKLINK does it in seconds.
For me, the site just confirms what I already knew.
But what would be truly useful, is displaying the actual rank of the book in every category.
Picking off the 3 displayed on the product page is easy. But searching out the ranks outside the top 100s - that is information I truly WANT.
Not sure what you're asking. I see it's showing Lacey & Alex in six categories, with the rankings, and also showing the overall ranking. (90,359)
Lacey & Alex: The Dagger of Ill Repute: A Fantasy Adventure with a bit of romance. by Tapscott, V.R. (Author) (B08BX23YC8)

It IS showing rankings for some categories and not others, perhaps it won't show rankings if the rank is over - 10,000? 20,000?
Maybe Rick will chime in.
Along that line, it seems unlikely you'll get useful information from someone by yelling at them that they're dead wrong and having a big thumbs down. He's providing a useful application - for FREE - and I'm sure he's interested in having it be as useful as possible. Perhaps we could work with him with suggestions for improvements rather than bad tempered imprecations.
