Search Engine Land’s Periodic Table of SEO Success Factors has been updated, with its fourth edition now available. It sees factors related to mobile, direct answers and site speed increase in importance. Factors related to search history have decreased. Factors related to site identity and personal social sharing have been dropped entirely.
Our goal with the Periodic Table of SEO Success Factors is to help publishers focus on the fundamentals needed to achieve success with search engine optimization.
To do this, the table doesn’t try to list all of Google’s 200 major ranking factors (most of which aren’t publicly known) or detail the search engine’s 10,000 subfactors. It doesn’t try to decipher if the keywords you want to rank for should be at the beginning of an HTML title tag or the end. It’s not about whether Facebook Likes count toward a ranking boost or not.
