Buy underpriced used books. Outfit a phone with an ISBN reading app, scan the ISBN numbers of books at used bookstores and thrift shops, and compare the asking prices with what the books are selling for on a site like Amazon. Whenever you get a good hit (which won’t be often but, since the process is fast, won’t take long, either), buy the book and resell it online. Be discreet about this, as the store managers probably won’t like what you’re doing.
When describing whatever it is your promoting, share your experience! If you can throw in some data or graphs to go along with it, even better. Back when I was more actively writing about eHow, I promoted an ebook that I read which helped quadruple my earnings per article. I created a graph that showed how much I earned before I read the book versus how much I earned after. To this date, that ebook has been one of the most successful affiliate promotions I’ve done on this blog.

Robo-advisors are diversified investment accounts that are automatically managed by a computer algorithm (as opposed to a human money manager). If you want to invest, but don’t have the money, or don’t want to invest with a money manager, robo-advisors are for you! Robo-advisors make investing easier—and cheaper—so they’re perfect for new investors.
