1998 updates

September 4, 1998

Google Inc. was founded by Sergey Brin and Larry Page.  The first algorithm was launched back in March 1998. The search engine was launched and Page Rank was invented. Its algorithm was based on the transfer of link weight between pages and the basic rule that initially all pages have a certain weight. The more resources link to a page, the higher the PR and, accordingly, the higher the place in the search results.

Two basic rules of the new system:

  • The more links leading to the page, the higher the PR, and the higher the place in the SERP.
  • The higher the Page Rank of a linking page, the more link weight it can transfer.
