Lindsay Buroker Tells you how to get your stuff into more categories with keywords.

Lindsey Buroker isn't a dedicated erotica writer (just wanted to get that out there since this is a blog on erotic writing and it's never a good idea to tie someone to a genre they may prefer not to be tied to.) but she has some great wisdom on keywords:

If you’ve published any ebooks through Amazon’s KDP dashboard, you know they allow you to select two categories (i.e. Fantasy/Epic or Science Fiction/Steampunk) for your work, and then they have a box where you can type in seven keywords, though they don’t really say if those keywords can be used to help you show up in the search results or what the deal is. They’re just… there.If you browse around Amazon, you may also have noticed that there are subcategories for ebooks that aren’t options in the dashboard (i.e. Science Fiction & Fantasy/Fantasy/Coming of Age or Romance/Paranormal/Witches & Wizards). Because some of these categories are so niched down (and because they’re not selectable on the dashboard), the competition can be low. It might only take a 50,000 sales ranking to appear in the Top 100.

It's a good article and you should go read it.

I'll add some of my own wisdom.  (that and five dollars will get you something called Coffee from Starbucks.)

Getting into multiple categories is one of the most important things yhou can do as an erotica writer...

IF your erotica is related to those categories.  If it isn't, if it's just a bog-standard erotica story that has a single raygun and is put into sci-fi, you will get Unhappy Readers.

Who will complain to Amazon.

You really want to avoid that.  So remember that keywords and categories, like anything else you do to boost your publicity, is part of attempting to create a long-term and loyal audience of fans, not simply getting someone to look at your book, feel deceived and return it, with or without a snarky review.
