Some people swear by this little money spinner. They have a free course so you can find out how to use it.
If you believe the hype, Google Adsense could be just the little money earner you need to help pay a few bills while you get your web site running.
Google certainly has no shortage of Mums, Dads and small business people who are happy with what Adsense has done for them (though keep in mind, some of these people get quite a lot of traffic to their web sites).
If you've never used AdSense, right now Google is running a free 10-week online course - you can sign up for the course here.
The site says the course is aimed at people who are new to Adsense or if you've been using it for years.
