It's eye-opening about how misdirecting one of my titles is, too. I do not write "domestic discipline spanking" books but clearly there is something about my book that is making the wrong people look at it. Got to change that. 
New genre for you?
No, just a purple prose title that--after four years!--I now see is costing me money by attracting the wrong sort of potential audience. Those people click and then read my blurb copy and do not buy.
That's the other part of the data that is fascinating. I suppose the prior iteration of information on these ads had much the same detail, but seeing the actual words people are using to search for a book, who then buy mine or don't buy mine, makes it that much more real.
I've been thinking about changing that purple prose book title, anyway. I've also been thinking about unpublishing it and the whole series, rebranding them all with a new series title and a new cover design, using a new pen name, and doing some selective revising of some of the books, too. The only things stopping me are 1) Chris Fox's advice that some series aren't worth the effort, 2) no time, 3) no budget for a big overhaul, and 4) no idea which cover designer to use.
But I added a batch of negative keywords to my ad, each one copied from the search terms, and that should make my book invisible to the spanking fans.
