It works by sending out automated programs, known as spiders or crawlers, to systematically browse and index web pages.

  1. Crawling:
    • use automated programs called crawlers or spiders to browse the web. These crawlers start with a list of known web addresses and follow links from one page to another.
    • The process of collecting information from web pages is known as crawling. Crawlers download web pages and follow the links on those pages to discover new content.
  2. Indexing:

    • Each search result usually includes a title, snippet (a brief description), and a link to the page.
  6. Continuous Updating:
    • continuously update their indexes and algorithms to ensure that the results remain relevant and up-to-date. Crawlers revisit websites to find new content and update their index accordingly.
