Half of this is a book published as blog posts, with the chapter numbers still attached and the chapters arriving out of sequence, so you will meet chapter eleven before chapter three. Once you know that, it becomes readable.
The material is a plain search optimisation course. How the crawlers pull keywords out of your text. Why a blog attached to a site keeps that site fresh enough to keep being indexed. How article directories work and what they demand before they will publish anything.
The other half covers direct marketing rather than search: two words that change how a piece of mail lands, a two step approach to selling instead of asking immediately, and three ways to build an email list that does not look like everybody else's. One post covers postcards specifically, which almost nobody writes about now.
Ten posts. Find the earliest chapter you can and read the course in order, then take the direct marketing pieces separately.
