Amazon Using Category MetaData to Filter Rankings

UPDATE 1: Here is a spreadsheet of books denoting their catagory metadata along with whether the book has an amazon rank. If you are a gmail user, you can (I think) access the spreadsheet for sorting. If you aren’t a gmail user, here is a web page of the spreadsheet.

Additionally, there is a Change.org email campaign that you can join to trigger emails to be sent to Bezos and Amazon customer service.

At the suggestion of someone I looked up the category meta data provided by the publisher to Amazon.    I looked up over 40 books that had been deranked and filtered out of search engines.   It appears that all the content that was filtered out had either “gay”,   ”lesbian”,   ”transgender”, “erotic”   or “sex” metadata categories.   Playboy Centerfold books were categorized as “nude” and “erotic photography”, both categories that apparently weren’t included in the filter.   According to one source, the category metadata is filled in part by the publisher and in part by Amazon.   

Heather with Two Mommies included this category metadata:

Books > Subjects > Gay & Lesbian > Literature & Fiction > Fiction > General
Books > Subjects > Gay & Lesbian > Literature & Fiction > Fiction > General AAS
Books > Subjects > Gay & Lesbian > Parenting & Families
Books > Subjects > Gay & Lesbian > General AAS
Books > Subjects > Teens > Social Issues > Homosexuality > Fiction

A Parent’s Guide to Preventing Homosexuality had this category metadata (note the lack of any reference to gay & lesbian categories):

Books > Specialty Stores > Custom Stores > Qualifying Textbooks > General AAS
Books > Subjects > Nonfiction > Social Sciences > Sociology > Culture
Books > Subjects > Nonfiction > Social Sciences > Sociology > Marriage & Family
Books > Subjects > Parenting & Families > Parenting > General
Books > Subjects > Parenting & Families > Parenting > General AAS
Books > Subjects > Religion & Spirituality > Christianity > General
Books > Subjects > Religion & Spirituality > Christianity > General AAS
Books > Subjects > Religion & Spirituality > General
Books > Subjects > Religion & Spirituality > General AAS
Books > Refinements > Binding (binding) > Paperback
Books > Refinements > Format (feature_browse-bin) > Printed Books

Lady Chatterly’s Lover included this:

Books > Subjects > Literature & Fiction > Erotica > General
Books > Subjects > Literature & Fiction > Erotica > General AAS

As did Jaci Burton’s Riding on Instinct:

Books > Subjects > Literature & Fiction > Erotica > General
Books > Subjects > Literature & Fiction > Erotica > General AAS

But Burton’s first book in the series, Riding Wild, had only this for category metadata and thus was not deranked:

Books > Specialty Stores > Custom Stores > Qualifying Textbooks > General AAS
Books > Subjects > Romance > Contemporary > General
Books > Subjects > Romance > Contemporary > General AAS
Books > Subjects > Romance > General
Books > Subjects > Romance > General AAS
Books > Refinements > Binding (binding) > Paperback
Books > Refinements > Format (feature_browse-bin) > Printed Books

Anything Goes by John Barrowman in paperback has an Amazon sales rank of 7,155.

Books > Subjects > Biographies & Memoirs > Arts & Literature > Actors & Actresses
Books > Subjects > Biographies & Memoirs > Arts & Literature > Entertainers
Books > Subjects > Biographies & Memoirs > Arts & Literature > General
Books > Subjects > Biographies & Memoirs > Memoirs
Books > Subjects > Biographies & Memoirs > General
Books > Subjects > Biographies & Memoirs > General AAS
Books > Subjects > Entertainment > Music > General
Books > Subjects > Entertainment > Music > General AAS
Books > Subjects > Entertainment > General
Books > Refinements > Binding (binding) > Paperback
Books > Refinements > Format (feature_browse-bin) > Printed Books

But the same book in hardcover has no ranking but does include this in the metadata:

Books > Subjects > Gay & Lesbian > Biographies & Memoirs > General
Books > Subjects > Gay & Lesbian > Biographies & Memoirs > General AAS

The Filly by Mark Probst includes these entries (among others, of course):

Books > Subjects > Gay & Lesbian > Literature & Fiction > Fiction > Gay
Books > Subjects > Gay & Lesbian > Literature & Fiction > Fiction > Romance > Gay
Books > Subjects > Gay & Lesbian > Literature & Fiction > Literary Criticism

Thus, as a “glitch” it was a remarkably targeted one that seems to support the emails that Mark Probst and Craig Seymour received from Amazon which was gay and lesbian works were deemed “adult” content regardless of actual content. This evidence appears to indicate that it isn’t so much a glitch but a specific policy. The question is then who implemented the policy of marking GLBT books as adult and who knew of the implementation? What kind of supervisory person signed off on it?

Alternatively, you could argue that it was a lazy programmer that decided to filter out all adult content and included GLBT for the heck of it but that doesn’t really address the emails to Probst and Seymour. You could also argue that it was a hacker that went in over the past week and inserted an algorithm that filtered out GLBT/erotic/sex content. Obviously, why the filter was implemented in such a way is a question only Amazon can answer.
