Have you ever wondered how "Google" is able to answer almost every question you ask?

Google just collect information from the website that best match the intent of the search query and display to you.

It is like you are in a big library where millions of the books available that covers every information available on the planet.

Now if someone ask a question to you what you will do? You would find the book that is about the topic of question, go to the relevant chapter and than the page that has answer.

Google does the same thing but faster,

Google has its data center where it keep a copy of almost(but not all)every page of every websites and google update these cached pages regularly. To find the web-pages Google has programs called spiders or crawlers that read the page content, images and links on the pages.

Whenever you search anything on Google, Google finds the relevant pages to that query and and display on Search result, The order of result is calculated by an secret algorithm.
