Advice Needed: Making Money using Google Adsense for Facebook

Does anyone have experience using Google Adsense on Facebook? Good/Bad?

I figured out how to do it using a website, however I am trying to do it with my Facebook pages I have.

I have close 3000 readers on my Coupon FB Page and 1600 on my other FB page.

I could build a website, however I’m not sure I’d have as many viwers, as on FB now.

Any advice is appreciated. Thanks!
