Electronic book : Search Engine Optimization Starter Guide

This document fist began as an effrt to help teams within Google,
but we thought it'd be just as useful to webmasters that are new to
the topic of search engine optimization and wish to improve their
sites' interaction with both users and search engines. Although this
guide won't tell you any secrets that'll automatically rank your site
first for queries in Google (sorry!), following the best practices
outlined below will make it easier for search engines to crawl, index
and understand your content.
