Advertising online has to be my favorite type of 'make money at home' deal. All you need to do is set up a website or blog and there are numerous pay-per-click advertisers out there, you just have to pick the right program. Best part about it is, it's FREE. Sounds easy enough, right? It is. You just have to do a few things.

Setting up a blog

Go to Blogger at (or any other blog site you wish- I use Blogger, it's nice and easy)

Set up an account with Google (or sign in to Blogger with an already existing account).

Create a blog about whatever you want.

Set up Google Adsense and/or another advertising program.

And as long as you are constantly adding new content to gain traffic then you should see in increase in earnings. It helps to have lots of followers who will read you blog daily.
