Importance or Popularity SEO
Importance or popularity refers to the relative importance, measured via citation (the act of one work referencing another, as often occurs in academic and business documents) of a given document that matches the user’s query. The popularity of a given document increases with every other document that references it. In the academic world, this concept is known as citation analysis.
It is not possible to determine Popularity and relevance manually.
It is just like calculating Earth’s entire population with single hand.
Instead, the search engine will design mathematical equations—algorithms—to define the quality. These algorithms often comprise hundreds of components. In the search marketing field, they are often referred to as ranking factors or algorithmic ranking criteria.
