HITS is the abbreviation of Hyperlink Induced Topic Search, which is translated as "hyperlink induced topic search". The HITS algorithm was proposed by Jon Kleinberg in 1997 and applied for the following expertise: //patft.uspto.gov/netacgi/nph-Parser?patentnumber=6 112202 According to the HITS algorithm, after the user enters a keyword, the algorithm calculates two values for the returned matching page, one is the Hub Scores, and the other is the Authority Scores. These two values are interdependent and affect each other. The hub value refers to the sum of the authoritative values of all exported links on the page. Authoritative value refers to the page where all import links are located（ High end website construction ）The sum of the pivot values of.
The above definition is ambiguous. We can simply say that HITS algorithm will extract two more important pages1, namely hub page and authoritative page. The hub page itself may not have many import links, but many export links point to authoritative pages. The authoritative page itself may not have many export links, but there are many import links from the hub page.
A typical hub page is a website directory such as Yahoo Directory, Open Directory or Hao123. This high-quality website directory is used to point to other authoritative websites, so it is called hub. The authoritative page has many import links, including many links from the hub page. Authoritative pages are usually pages that provide truly relevant content.
Becoming an authoritative page is the first priority, but it is difficult. The only way is to obtain high-quality links. When your website（ Beijing website production ）When it cannot become an authoritative page, let it become a hub page. Therefore, exporting links is also one of the current search engine ranking factors. Never link to other websites is not a good SEO method.
