I want to refresh my knowledge of SEO in a very efficient and organized way. I figure the best way of doing it would be reading a book on SEO which was recently published and takes into account all the recent changes.
The problems with such books is 90 percent of them aren't worth anything and contain only basic information. User reviews on sites like Amazon also do not help much - it looks like most of the reviewers had some sort of deal with the author or publisher of those books, that's why they say that the book is "the beautiful and most trustworthy thing after the Bible".
So I am kindly asking to recommend me something that is rally worth reading. I take it folks around here can be trusted.
