Periodic Table of SEO Elements

Here are the elements of SEO that everyone needs to know and understand to get a web site indexed fully, ranked well and to avoid penalties. This infographic distills 200 plus signals down to the following nine main elements, each with sub-elements and strength ratings of +3 (strongest positive factor) +2, +1 and continuing penalties downward with -1, -2 to -3. Similar to the actual Periodic Table (seen below) of the Elements this graphic plays off of – it is color coded by hue to indicate

  1. 5 CONTENT Elements
  2. 3 HTML Elements
  3. 3 ARCHITECTURE Elements
  4. 3 LINKS Elements
  5. 2 SOCIAL Elements
  6. 2 TRUST Elements
  7. 4 PERSONAL Elements
  8. 6 VIOLATIONS Elements (minus factors)
  9. 2 BLOCKING Elements (minus factors)

Below is a condensed version of the SEO Table of elements, and here is a full sized version with details added.

In 2006, Google had the display below at the Google Dance, held on the Google campus during Search Engine Strategies 2006 conference in San Jose. (I still have the Google Dance T-shirt souvenir).
