So, whenever we search something on Google, it will into its database and display results accordingly but only those results which have been indexed and stored in the database not every live website on the internet.

Now comes the big question, How did Google decide which website to index and which website to be ignored.

Of Course, Google does not use any kind of magic stick to give useful information to the user because they don’t have any. So, they created some programs, codes, and algorithm and runs these algorithms and codes Google uses Spiders or Web-Crawlers.

What are Spiders/Crawlers:

Spiders are code/programs/crawlers which are responsible for scanning the websites on the internet.
Suppose if I request Google to send spiders to scan my website for indexing that it will come to my website and scan some elements/codes and content of the website that also includes the title, description, and links available on the webpage and a hyperlink is like a bridge to go from one website to another for crawlers/spiders. Every time it finds a hyperlink, the spider will start crawling the webpage which connected with that particular web address.

Suppose, a webpage has 10 external links (pointing to pages on another websites) that spiders will separate and start crawling those 10 pages with same procedure of scanning content, title, description and finding more hyperlinks. In this way, Spiders Crawl/Scan the whole internet to fill the database of their search Engine.
