The search engine that decides page rank is Google. Google's PageRank algorithm is the foundation of its search engine and determines the ranking of web pages in its search results. PageRank is a complex algorithm that evaluates the importance and relevance of web pages based on various factors.
PageRank was developed by Larry Page and Sergey Brin, the founders of Google, while they were Ph.D. students at Stanford University. It was named after Larry Page and is a play on words with "page" referring to web pages.
The PageRank algorithm works by analyzing the link structure of the web. It assigns a numerical value, known as PageRank score, to each web page based on the number and quality of links pointing to it. The more high-quality links a page has, the higher its PageRank score will be.
When a user performs a search query, Google's search engine uses the PageRank algorithm to determine the relevance and importance of web pages that match the query. Pages with higher PageRank scores are considered more relevant and are given higher positions in the search results.
