A. Crawling and Indexing:

      1.       Crawling is a program or software of a Google that is also called Robot, bot, or spider that reads a new web pages in order to create entries for index. In simple words, Crawler is typically programmed to visit sites that have been submitted by their owners as new or updated.

      2.       Index collects, parses, and stores the website information in their database. According to Google, its search engine has been crawled billions of web pages and is well over 100,000,000 GB in size which is too much.

B. Algorithm:

          Another step from which Google passes and provide accurate result to it’s users. Google changes its algorithm about 500 to 600 times in which Google Panda and Google Penguin was the major change which affects  ranking of most webpages. These algorithms follow a series of steps in order to provide clear, accurate and useful sources to its users.

      1. Analyze words

                Google has its own Language model by which it analyzes words provided by the users that what its user wants to know.

      2. Match search

                In this step Google algorithm search out the webpages that match a query

      3. Ranking pages

      4. Considering context

                Google also consider your location, search history and search settings to display result that is most useful and relevant to you .

      5. Return result

                After Google done with these steps they display a result to user what they was searching for.

C. Useful Response:

  A bunch of pages available on the internet Google still makes sure to provide you accurate and rich content quickly that you are searching for.

So these was the steps that Google to pass from and provide result to the Users.
