Types of Search Engine Success Factors

Search engine success factors are majorly into 3 main groups in the search engine land periodic table. 

• On-The-Page SEO
• Off-The-Page SEO
• Violations

Each of these groups have further sub-groups and in turn each subgroup have 1 or more individual seo factors with specific importance and weight for each.

• In the periodic table the 1st letter in the SEO element represents the subgroup to which it belongs and the 2nd letter is the individual SEO factor.
• No single SEO success factor guarantees top rankings.
• On-The-Page SEO factors are purely under the publisher/owners control and this includes type of content being published, HTML clues that are provided to assist both search engines and users relevancy and if the site architecture is aiding or obstructing the search engines.
• Off-The-Page SEO factors are  not directly controlled by publishers. These signals are used by search engines as they understood that depending on On-The-Page SEO factors alone wont yield good results from the billions of web pages.
• Violations are techniques deemed by search engines as SPAM or BLACK HAT that are actually meant to deceive or manipulate search engines grasping about any specific websites relevancy or authority. 
• The table has SEO elements that are either marked with numbers ranging from -3 to +3 and reflected a hue as well to represent their importance. Those elements that are marked +3 are more important and it doesn't mean that those that are marked +1 are worthless, it just means that they are relatively less important to speak.

These are not the only factors that are to be considered but there are many other signals and subsignals from Google, instead the periodic table focuses on the big picture. The periodic table was designed with the purpose of avoiding being ultra-specific as such things may be distracting.
