Without RankDex, search engines may still be using keywords, not links, as their primary ranking factor today. RankDex is the basis of every major search engine’s ranking algorithm today, predating Google’s “PageRank” by two years and being referenced in Larry Page’s first patent. For the first time, it used “link analysis” to determine the importance of web pages by the number of other pages linking to them. In 1996, Li created and patented a system called RankDex, for ranking the importance of web pages in a search result.

After leaving university, Li joined a New Jersey based division of Dow Jones, where he built software to manage the online edition of The Wall Street Journal. Li then went on to study at the University of Buffalo in New York, where he earned a doctorate in Computer Science. They helped Li get into Peking University, where he studied Information Management. His parents were factory workers, with four other children to care for. “Robin” Li Yanhong is mostly an unknown in the western world, but one of the richest men in China, with an estimated net worth of nineteen billion dollars. Yahoo, AltaVista and Lycos dominated, with significant investment propping up the loss-making sites. A new generation began using websites more than books, and search engines more than web directories. Internet-connected computers started to become widely accessible in schools, libraries and homes across the globe. The success of Yahoo was all packaging, with a fun brand and a user-friendly interface. They bought and borrowed third-party tech, until the acquisition of Inktomi (a search engine for hire) in 2002. To the annoyance of their lesser-known rivals, Yahoo didn’t build any significant new technology. “Yahoo!” started as a traditional web directory in 1994 by two Stanford University graduates, then launching a search engine in 1995. But the most significant success was Yahoo, founded by Jerry Yang and David Filo. Excite and AltaVista both launched in 1995, along with the less well-known MetaCrawler, Magellan and Daum. Two years after Aliweb, search engines became mainstream and big business. A directory based on the original DMOZ database and maintained by former DMOZ editors, still exists today at.

Editors were found to be selling inclusion in the directory, after a DMOZ listing was rumoured to increase a website’s ranking in search engines.ĪOL failed to resuscitate DMOZ several times and eventually took the website offline. Commercial content creators such as CNN were given editorial rights to add/edit/delete entries, putting the impartiality of the project in question.

Volunteer editors of the directory felt betrayed, becoming unpaid workers of AOL, rather than a noble, free and open initiative.

The directory’s objectives became blurred when AOL acquired Netscape, and the cost of running it for free came into question. A year later DMOZ had over a million URLs listed, and it peaked at over five million URLs, before closing in 2017.

The directory became the default way of finding information on the web for many, with a search function for faster directory navigation.ĭMOZ was acquired by Netscape later that same year, having indexed (listed) around 100,000 URLs. One of the most well-known directories was DMOZ (or the Open Directory Project), created in 1998 by two engineers at Sun Microsystems.

Rather than having to download every message in a newsgroup and searching for information or URLs within them, users could now visit a directory/portal and navigate through the categories to find the relevant web pages. Some users began creating web pages that collated the URLs shared in newsgroups, into catalogues or directories. Even after the broad adoption of Sir Tim Berners-Lee’s technology, web pages were often shared and linked to within special-interest newsgroups. Usenet newsgroups were how internet users communicated, a decade before the web was invented. Berners-Lee declared that the technology must remain freely available, with no patents or royalty-fees, to be accessible to everyone. He also invented HTML (based on CERN’s SGML markup) for formatting text-based content, distributing the technology outside of CERN in 1991. To make HTTP easier to interface with, Berners-Lee built the world’s first web server and web browser to navigate it in 1990. It used a technology called Hypertext Transfer Protocol (HTTP) that transmitted data over TCP/IP, which is why all URLs start with “HTTP” to this day. It was the English scientist, Sir Tim Berners-Lee, who invented the World Wide Web in 1989 while working at CERN in Switzerland.
