What Is A Search Engine?

• Search engines are software programs that allow
  people to find the information they are looking
  for just
• at their fingertips. Search engines are prompt in
  showing results by indexing pages or scanning
  millions
• of publically available websites online. The
  whole process is managed by complex algorithms
  which
• ensures a list of relevant websites at the top.
• When a user searches for a specific term, search
  engines show results according to the specific
• keywords, page title, and content.

Crawling

• Each search engine contains plenty of computer
  programs called web crawlers (aka. spiders).
  Their job is to find information that is publicly
  available on the internet. Let's make it easier
  for you. Crawlers scan the internet and find web
  servers and hosting websites. For better
  crawling, they create a list of web servers and
  the number of websites hosted by each server.
  Then they visit different websites using
  different techniques and discover the number of
  pages available on the websites whether they
  contain texts, images, videos, or any other
  format (HTML, CSS, JavaScript, etc).

Ranking

• The third and final stage decides which pages to
  show in the SERP as per specific query. The
  process involves complex algorithms. Algorithms
  are an amalgamation of rules and analysis that
  ensures user experience by providing relevant web
  pages.

How Do Search Engine Algorithms Work?

• How search engine algorithms work is tricky. Day
  by day, algorithms are getting more complicated.
  Unlike earlier, when queries were answered based
  on matching titles of the pages. It is inferred
  that Google considers 255 factors before making
  it rank on the first page. These factors are yet
  to be cracked out, but assumptions are made
  continuously. Let's have a basic idea of how
  search engines' algorithms work.

• 3. Yahoo!
• 4. Yandex
• 5. Baidu

Conclusion

• Lastly, search engines are way more complex than
  they appear in their interfaces. As they are run
  by computer programs, they require a large amount
  of data to operate automatically. Human
  intervention is required only when it comes to
  designing but it has now become easier with
  artificial intelligence. As a webmaster, your job
  is to make their crawling and indexing process
  easier through creating websites.
