OK - to answer some questions that haven't been getting answered or got shitty answers to them:
1. Google HAS been doing this for YEARS.
2. Yes, Google is & will pay you monthly.
3. I "was" getting anywhere from $400-900 per month doing this back in 2009-10.
4. IT IS as easy as it sounds (signing up that is) for those who think it sounds like a "scam" or think there's "more to it" - there's not.
5. It still takes a lot of work to get started, as mentioned already, you have to be internet savvy, a reasonably good or entertaining writer, & know how to build traffic FAST.
6. NO - the "clicker" or "reader" doesn't have to buy anything in order for YOU to be paid. Google pays you PER-CLICK not PER-SALE.
7. Reason Google does this? Do you have ANY websites bookmarked that you MIGHT buy something off of later in the future? Google is hoping you click an ad, you are interested, you either buy or you bookmark that site for later use. The company belonging to that site address that you were forwarded to pays Google for Google getting you. So in a sense, the only "pyramid" scheme going on is between you, Google, & the ad-site itself.
This is a great program offered by Google, I'm surprised not as many people have heard about it. Good luck, I will check your blog out & probably click a few ads for you on the way out.
