The Complete History of Search Engines

It’s hard to believe that Google Search officially launched on September 27, 1998. In the history of search engines, Google has set the standard for innovation and excellence. Their ever-changing search algorithm continues to meet the increasing demands of searchers worldwide.

To understand how Google search works, we need to explore the history of the Google Search Engine.

To do that, we start at the beginning of search and continue through Google’s storied existence.

Search Engine Timeline

1990– The first search engine is Archie. A year after they invented the world wide web (WWW), the early search engine crawled through an index of downloadable files. However, the limited data made only the listings available, not the content.

1991–  Tim Berners-Lee, the inventor of the WWW, created a virtual library to help users find URLs for different websites. The CERN webservers hosted the library at the beginning of the internet.

1993– JumpStation brought a new leap with their linear search, which showed a page’s title and header in the same results. The search engine ranks results in the order they were found.

1994– David Filo and Jerry Yang create Yahoo! Search. The site was the first collection of web pages across the internet. They include man-made descriptions for the URLs.  Site owners can add Informational sites for free, but commercial sites have to pay $300/year.

WebCrawler– the same year that Yahoo! Search launched saw the launch of Web Crawler. They created the first search engine to index entire pages—the amount of data required to do the search engine is too slow to use during the day.

1995– Lycos search engine was also launched in 1994. The search engine cataloged over 394,000 documents by August. By January 1995, they had over 1.5 million papers cataloged.

1996- Larry Page and Sergey Brin created the predecessor to Google BackRub. The initial idea used backlinks to help rank websites for better search.

The backlinks show you how one website that links to another site counts as a vote. This idea is the basis of a website’s authority. Today’s algorithm still relies on the same initial concept. It has advanced tremendously in the past 20 years, but backlinking still affects the ranking.

AskJeeves– The first search engine where they attempt to have human editors respond to search queries. The site became easy prey to spam.

Inktomi– A pioneer in the paid advertising model. Inktomi provided an early precursor to pay-per-click (PPC) ads.

Lycos– Still the largest search engine. Lycos now has over 60 million documents indexed.

1998– Google officially launches.

2012- Following the Panda release, Google launched the Google Penguin algorithm update. This update penalizes sites for buying links or using link networks to boost search rankings.

2013- Google revolutionizes its search algorithm again with its Hummingbird update. The algorithm is the first attempt by a search engine to understand the human intent behind a search query. The history of search until then focused on how to improve language queries.

Bing– Copying Google, they add a mobile-friendly algorithm.

2016- Google Possum attacks local spam sites just like the “nofollow” tag a decade earlier removed spammy websites.

Google also integrated the Google Penguin update in the core ranking algorithm to ensure the death of link farms

Final Thoughts

The history of search is fascinating. Initially, no one would have suspected that an upstart like Google would dominate search engines the way they have over the past few years. However, looking back, it’s clear that Google was the first to understand what customers truly wanted. They were the first to focus on providing relevant and accurate search results, and they were the first to use artificial intelligence to improve their search engine.

As search engine marketers, we can learn much from Google’s history. By understanding how Google has evolved over the years, we can better understand what it takes to rank well in search results. We can also stay ahead by anticipating Google’s upcoming requirements.
