I'm assuming you need paypal?
It's a system that puts ads on a site. The site then makes money every time the ad gets clicked. People trying to sell certain stuff will post their ad with Google so it can show up on other sites. It's a pretty common way for places to make money all around actually. Google makes money because people pay to put their ads up. The people with the ads make money for the clicks, and the people trying to sell stuff usually reach a large enough audience to do so :)
Copied from their own page: Google AdSense is a free, simple way for website publishers of all sizes to earn money by displaying targeted Google ads on their websites. AdSense also lets you provide Google search to your site users, while earning money by displaying Google ads on the search results pages. http://funadvice.com/r/3kvcancqpj You don't need PayPal - they offer payments by cheque, EFT, and Western Union
For what part of it? Using Adsense on your site? Not sure. That seems like a logical way for Google to pay you though, so I would assume either that or an address for them to mail a check to you. Checks are out of date though, so I'd guess Paypal. That's how I get paid for everything I do :)
I was reading about it on "my settings" and it says you get paid. Lol DO you need paypal for it?
Damn, I can't write a howto and get paid then . Lol
