OrganicSEO.org started in 2005 to create an electronic book detailing Search Engine Optimization (SEO) strategies.
Organic SEO: The Organic Book of Search Engine Optimization is itself an organic book. Content is written and updated on a regular basis -- the most recent version is always available on http://organicseo.org.
The original version of the Organic SEO book was in wiki format; however after many painful hours of deleting spam from the wiki, I decided to switch to a custom e-Book format and retain control over the content that appears in the book.
I'm excited about this new project and have great expectations for OrganicSEO.org.
