Search Inside Feature
I suggest signing up for the free “Search Inside” Feature with Amazon. You just have to contact them and then follow their directions to send a pdf file of your book. They were very prompt activating "search inside". I know that many people want to check out the first chapter before buying. Send pdf files instead of a physical book to be scanned -- it takes less time to activate it. The dust jacket needs to be a jpeg, and the text needs to be one pdf file. Both files need to be named with the ISBN number and zipped together into a single zip file.
All I did was click on the link beneath my book image (it is addressed to publishers, but that's okay). I gave my name, the title, the ISBN and told them I owned all the rights to the book and wanted to sign up. Within a day or so, they sent me instructions. You can send 2 copies of your book to them, or you can send a pdf file. If you want to send a file, you have to let them know, so they set up an account.

Create some Listmania Lists on Amazon. Include lots of books on your topic. Maybe someone will view your list and buy somebody else's book. But when I did it, my goal was to get my book seen in a group with other books on that topic. I figured that being included on Listmania increased its visibility. If I get one sale out a 100 views of that List, it was good money value, 'cause it was free advertising.
