How Search Engines Works A simple and Powerful explanation

Google doesn’t find every page on the web. Search engines start at some popular spots and repeatedly follow links from there, “crawling” their way across the web. A new website that nobody links to will not be found unless its admins explicitly submit it to Google, asking for it to be crawled.

How Google Gets to know about your domain?

Google gets to know about any new website through these 3 sources;

• Domain Discovery: Google DNS: Almost every time you visit a website, it needs to get the IP address for the website. Google DNS is a very popular DNS around the world. DNS logs are very useful for discovering domains.
