How does the Google ranking works?

PageRank is a way of measuring the importance of website pages. According to Google: PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is

With great difficulty

Google ranking systems are designed to do just that: sort through hundreds of billions of webpages in our Search index to find the most relevant, useful results in a fraction of a second, and present them in a way that helps you find what you're looking for.

Thanks for the useful information and well said @henrybolt

To rank websites, Google uses web crawlers that scan and index pages. Every page gets rated according to Google's opinion of its authority and usefulness to the end-user. Then, using an algorithm with over 210 known factors, Google orders them on a search result page.
