PageRank is a crucial computer^[2] algorithm^[1], developed by Larry Page and Sergey Brin, that measures the relative importance of web pages. This is done by assigning a numerical weight to each page based on the number of links directed to it, effectively using the internet^[3]’s vast linking structure as an indicator of an individual page’s value. The algorithm involves a complex process of refining and adjusting these values through repeated iterations. Beyond its application in web search, PageRank has been used in various other fields such as bibliometrics, social networks, and academic ranking systems. However, it’s also worth noting that attempts to manipulate PageRank for higher rankings have led to the development of detection methods to maintain the algorithm’s reliability. Overall, PageRank has significantly shaped the way we navigate and understand the digital world.

Terms definitions

1. ↑ algorithm. An algorithm is a well-defined sequence of instructions or rules that provides a solution to a specific problem or task. Originating from ancient civilizations, algorithms have evolved through centuries and are now integral to modern computing. They are designed using techniques such as divide-and-conquer and are evaluated for efficiency using measures like big O notation. Algorithms can be represented in various forms like pseudocode, flowcharts, or programming languages. They are executed by translating them into a language that computers can understand, with the speed of execution dependent on the instruction set used. Algorithms can be classified based on their implementation or design paradigm, and their efficiency can significantly impact processing time. Understanding and using algorithms effectively is crucial in fields like computer science and artificial intelligence.

2. ↑ computer. A computer is a sophisticated device that manipulates data or information according to a set of instructions, known as programs. By design, computers can perform a wide range of tasks, from simple arithmetic calculations to complex data processing and analysis. They have evolved over the years, starting from primitive counting tools like abacus to modern digital machines. The heart of a computer is its central processing unit (CPU), which includes an arithmetic logic unit (ALU) for performing mathematical operations and registers for storing data. Computers also have memory units, like ROM and RAM, for storing information. Other components include input/output (I/O) devices that allow interaction with the machine and integrated circuits that enhance the computer's functionality. Key historical innovations, like the invention of the first programmable computer by Charles Babbage and the development of the first automatic electronic digital computer, the Atanasoff-Berry Computer (ABC), have greatly contributed to their evolution. Today, computers power the Internet, linking billions of users worldwide and have become an essential tool in almost every industry.

PageRank (Wikipedia)

PageRank (PR) is an algorithm used by Google Search to rank web pages in their search engine results. It is named after both the term "web page" and co-founder Larry Page. PageRank is a way of measuring the importance of website pages. According to Google:

A simple illustration of the Pagerank algorithm. The percentage shows the perceived importance, and the arrows represent hyperlinks.

PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.

Currently, PageRank is not the only algorithm used by Google to order search results, but it is the first algorithm that was used by the company, and it is the best known. As of September 24, 2019, all patents associated with PageRank have expired.
