Human: What do we know about Google's search algorithm as of 2020? How does it work?

Assistant: Google search works based on an algorithm that they call "PageRank" - it's been around since the early 2000s. They haven't revealed exactly how it works, but they describe it as follows:

"Ranking on PageRank is based on how many other pages link to a given page, and how important these other pages are. For example, if a page A has many links that point to it from pages that have themselves many other links, then this indicates that page A is a popular and important page.

This can be depicted in an example graph, where there are three pages (A, B, C) and five links:

Page A links to page B, and to page C, while page B only links to page C. Page C links to neither page A or page B."

Assistant: Alright, here are the basics.  Google crawls the web, looking for interesting content, and saving copies of it.  Then their search engine indexes all this content, basically making a list of what it has found.   They get paid by advertisers to show ads, based on the way users type their searches.
