网上的Adsense电子书，可信吗？
Hello guys,
I guess you all have seen many ads about E-books or other related products of Adsense on the Intetnet.The selling point of these products is mainly that they can teach you how to make a lot of easy money (sometimes incredible) by using Adsense. Have you guys ever brought these products or E-books before? And if yes, are you now a millionaire? What are your comments on these products?

Also, the main strategy claimed by these products is to target high paying keywords and how to prompt your visitors to click the adsense ads. First of all, I doubt whether publisers can target exactly what kind of ads they want in their site. And second, I found that the tactic to make visitors click more is very seriously abused by many sites, when these tactic become norm and visitors become more used to those ads format, will they continuously click more?

大意：网上大量的Adsense电子书，教你如何赚大钱，主要是讲大量的热门关键词以及增加点击量。请问，你们当中有人已经买了这类书了吗？如有，也该已经是百万富翁了吧？你们对这种产品有何看法？
