HOW SEARCH ENGINE WORKS (CRAWLING, INDEXING, RANKING) Google search, known as one of the most popular search engines across the world, has its own mechanism of understanding the information asked. Every day, Google search engine processes billions of queries using its algorithm and tries to provide the best possible search results. Google search follows its algorithm and goes through the information available on its platform.

CRAWLING
When one types something in the search bar in the first place, it finds what pages exist on the web. The crawler or spider takes note of all the keywords, web pages, descriptions, etc to learn your data search. This way the Google spider goes to the already visited page which the user has visited in the past for better search results. Google does not accept payments to crawl a site or rank it higher.
INDEXING
After a page is discovered, Google understands the data of the page. Google analyses the content such as the videos, images, the catalogs, etc embedded on the webpage. This process is called Indexing. This information is then stored in the Google index, a huge database stored in computers.
RANKING
When the user searches something, Google then scans through the indexed pages to give the best result. It gives attention to factors like language, location, device, etc. With the same search query restaurant near me, search results for a user in India will be different from the person located in the USA. This is how the results are varied.
It ranks pages programmatically. This is how Google works to give the search results after going through a simple, yet complex process.
