If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
You may decide to create free videos as extra content for your blog, and not sell them at all. If this is the case then you can still make money from these videos by selling advertising space on them (in the same way as discussed for monetizing podcasts).

Use website’s like Izea to help you connect with companies willing to pay to advertise on your blog.

As long as the affiliate has done her homework and chosen a trustworthy affiliate program, she needn’t worry about non-payment.
