Narrowly focusing on one problem can lead to many more failures than you might have initially had to solve. Peter J. Meyers (aka Dr. Pete) believes the majority of SEO problems occur because people rarely consider the entire project.
Pete writes that 80% of bad SEO boils down to missing the big picture -- whether trying to get every page indexed, ranking for one keyword, or obsessing over link quantity. That big picture includes the 4 Rs: Robots, Ranking, Relevance and Results. For each of the 4 Rs, Pete provides tools for measuring progress.
