All the alternatives work only if your website or blog is high with traffic. Sadly, these options also work well in countries where the ads are relevant. I will tell you one truth that from where I am, Southern Africa, I get a lot of Google Adsense clicks that would have earned me lots of money if I was in the USA or elsewhere, yet a majority pay $0.00.

What has worked for us, I'm sure it would work for others from other parts of the world where such ads may be less relvant, is freelancing. I have earned lots of money in dollars through fiverr.
