Question by : Created an account with eHow to make money writing articles, is there a catch to affiliate with google adsense?
I know that becoming affiliated with google, amazon, eBay, etc. is the only way to get paid because they supply the ads that people earn you money, but is there some sort of catch to this? Writing online article to make extra money without having to pay for anything like membership seems a little too easy and too good to be true. Is there anyone on here that is already doing this who knows anything?
Oh ok cool. So it is completely safe to give them my account information so it gets deposited automatically when I earn money?

No catch at all. The way that it works is that other companies pay for a google counterpart service which is called “Ad Words”. This service allows them to show up at the top of search results, this is the money that you’re getting, so basically, google is not giving out any money for free.

Google Adsense <--> Google Adwords
they balance each other out.
