Great post, Sean! I have been using Adsense for the most part for two years now and each year, due to great content, my income has doubled. Thanks for all the great content, and this is sure to open my eyes a bit more to the likes of Amazon, which, I will admit, I have been ignoring due to the way they treat their affiliates. But, maybe it’s just me being a turd….
There are so many sites available on the web. Some of them look identical, some other aren't even worth a mention. Wonder why? That's always a good idea to learn from the example of the most impressive and successful web designs. There must be something in their designs that attract the target audiences and makes their websites stand out from the competition.
I would like to add that for information products, a lot of the time it’s pretty easy to rank for “information product review”. I recently did a review of a popular ebook that is a month long discipline program. I went about it by doing the actual program and documenting everything. At the end of the month I wrote up a 2700 word article summing up the whole experience.
