In 1998, Larry Page and Sergey Brin’s unusual observation about web links established the foundation for Google search

Google founders Larry Page and Sergey Brin did not aim at developing yet another search engine on the Internet in 1998. These two Stanford University graduates were simply wondering about making their search results more trustworthy.Back then, the first search engines used keyword-matching technology that helped to bring relevant results to search queries. However, such an approach had its pitfalls, as these search engines could not distinguish useful and credible pages.These students hypothesised that there were some intrinsic indicators of trust on the World Wide Web. Their assumption was quite simple. They assumed that if many websites link to certain pages, those pages may be credible, just as scientific articles cited frequently by other scholars. This concept gave birth to Google Search. From mere navigational aid to recommendationAs described by Stanford Engineering, the founders used an analogy between website linking and citation networks in scientific literature, wherein credible papers are frequently referred to by numerous scientists.Unlike other search engines before Google, Page and Brin viewed links as recommendations. For instance, a webpage that is extensively cited by credible sites can gain prominence over one with repetitive keywords.According to Stanford University materials on the PageRank algorithm, significant pages usually have links from other significant pages. Hence, the concept formed the foundation of a recursive system, whereby authority could propagate across the network. The implication was profound. Rather than focusing solely on textual content, Google sought to comprehend the interconnections between pages.The web historian John Battelle later described Google's approach as one of the earliest efforts to map the web using the behavioural patterns of people rather than mere keyword counts. The approach provided Google a competitive edge, especially during the rapid growth of the web in the latter half of the 1990s.BackRub was the first name for GoogleGoogle began its journey as the BackRub project. According to Stanford University archives, the term arose from the system’s emphasis on backlink analysis, which involves examining links leading to a webpage from other websites. The search engine analysed the interconnections between pages on the World Wide Web.The domain name “google.com” was secured in 1997, prior to the official founding of Google in 1998. According to Stanford history, the ranking technology was already developed during the founders' graduate studies.This chronology proves that Google did not emerge primarily as an advertising venture. Instead, it grew out of a unique technical innovation. Technology preceded the company. Why PageRank appeared to be unique among earlier search enginesBy the late 1990s, the internet had become highly saturated. Countless webpages vied for attention. Keyword-driven systems were unable to differentiate useful content from spam and manipulation.PageRank provided an alternative solution. An article on the Stanford CS224W research reading states that pages with more incoming links tend to have high scores according to PageRank. Links were interpreted as signals that others considered a webpage important.The technique proved successful since it replicated the way in which reputation works in academic settings and among people. People tend to trust recommendations made by reputable sources. Google's initial search results were clearer and more relevant in part because they accounted for reputation throughout the internet instead of counting the number of times words showed up. According to the Stanford Engineering Department, during the early days of search, PageRank became a proxy for credibility.The technique rapidly went from being researched to becoming a businessResearch projects at universities often stop once completed. It did not happen to Google. Page and Brin started their Google Inc company in 1998, based on PageRank, which they created during their graduate work. The shift happened rapidly because the creators were aware of the issue of internet growth. As the internet grew, users required an efficient approach to organising their searches. It is precisely this method that their algorithm offered.The company’s rapid rise over the next few years revolutionised the use of the internet. Searches were becoming quicker, better organised, and more integrated into daily activities.Why the 1998 revelation continues to remain relevantThere is something incredibly simple about the underlying premise of Google’s birth. Page and Brin realised that humans consistently create clues about whom they trust. In the internet environment, this clue took the form of hyperlinks between sites.Using this knowledge, they developed a ranking algorithm that could adapt to the ever-growing internet. The success of Google was not merely about technology or business sense. It was based on a keen observation of the user.Hyperlinks were not simply shortcuts to other pages. They were proof of recommendation and trust.
