What are some free ways I can advertise a book that I have recently self-published?

Forums that have the same subject as your book. For example, if your book is about how to get rid of acne, you will want to find forums about skin care, acne cures, etc.

You can check for any forum by going to Google and insert:

forum + acne

into the search box.

Post an internet blog, that way, when someone searchs for a book with your key words, it will come up in your blog and you can freely promote it their.

Craigslist, ebay, clickbank and possibly Amazon.
