SearchMetrics recently published a very thorough and insightful SEO ranking factors study for 2013.
They also created a useful infographic
Key findings:Exact mach domains and keyword stuffed links no longer work as effectively as they one did (surprised?)Due to very strong social signals, brands do better than other more optimised websites.Social signals are as important as ever to ranking.Quality content remains very important.Quantity and quality of backlinks remains a top priority.Basic on-page optimisation techniques are still a must.
