How to make money online search

I did a search on Google for the phrase "how to make money online by blogging". A plethora of websites come up in my search. I randomly clicked through these sites to see what they have. Most of these sites seem to claim that their blogs exist to teach people how to make money. Most of them have similar web layouts and the categories are almost identical on some of them. It never fails when I notice on the upper right hand corner of these sites is an email subscription box asking the readers to subscribe to some form of ebook. Scattering among the text are several hypertext links of Google "friendly" keywords. Whenever I hover my mouse pointer over these links, an ad would pop up. If you clicked on one of these ads, it will take you to the advertisers' homepage where the products can be purchased. If you bought products from these websites, the sites that led you to the advertiser's page will receive a commission on those purchases. There are several other ways of making money being discussed from these sites, but I will have to defer that to another post.
