How I make $400 a month in Passive Income by Self-Publishing
Its quite amazing how much money you can make with self-published books. For example I wrote a book about Decoding CAPTCHA's. I have the top ranking post on most search engines for this which is the only marketing channel.I collect about $35 a month from it without spending any additional time marketing. Not very much but such a small niche it really surprised me.Oddly enough the main reason for writing the book was to deflect all the emails I used to get about the subject. Not only did it achieve this aim it supplies beer money for me every month.
