Search Essentials and Spam Policies
Google's published documentation setting out the technical requirements, the prohibited practices, and the recommended approaches for appearing in search.
Analogy Mental model
The exam regulations and the criminal code in one document. You do not need to memorise it, but the lines that end your eligibility must be known by heart.
In practice What you actually do
The old webmaster guidelines have been reorganised into technical requirements, spam policies, and best practices. When anyone offers a shortcut, open the spam policies and check the technique against them; anything listed there is disqualified regardless of what the case study claims.
