Save your money. The reason people sell ebooks is to make money. There is nothing in any ebook that can't be found trawling decent forums (like this). I keep seeing an adwords ad for "I pay my mortgage with adsense -buy my ebook find out how...". People cash in on other people's desire for easy money. That's a sales hook. I earn slightly more than my mortgage with a site that is 12 months old. How? Through content growth and link building, not through "get rich quick schemes". But by patience and learning from cleverer people than me who drop tips in forums like these. Learn a a little HTML, learn a little SEO, get lots of fresh content - providing your niche is not too competitive you should do OK. And don't pay anyone for the advice - its out there!!
Ewen Chia is from my country... He once log in "live" in front of us from his clickbank account and at least shown $300,000 for 2007 earning from ONE of his profitable program
JC states at one of his latest videos he earns $500 per day average from adsense... I know a few guys making 2, 3 or 4 times that and guess what? THEY DON'T SELL BOOKS!
Oh no no no... Look at the big picture.. Say his ebook is 10$ but if 10000 people buy it you know how much money he will make.. Thats the strategy..
Why would you buy it when you can get all the info you need here at DP? Why would you call it "Adsense Secrets" when you can buy it for just a few bucks? It should be called "Adsense Public Secrets" I think Joel Comm is a genius! He knows most people are lazy and greed.
