Search engines
Search engines are essential tools that allow users to navigate the vast information available on the World Wide Web, which consists of billions of pages across countless websites. Emerging in the 1990s, search engines revolutionized how individuals locate information, quickly becoming a fundamental part of internet usage. The first search engine, Archie, was developed in 1990 and set the stage for future advancements, with notable contenders like Yahoo!, Google, and Bing offering innovative features that enhanced user experience. These platforms use sophisticated algorithms and indexing methods to efficiently retrieve relevant content based on user queries, whether through Boolean search terms or natural language.
The success of a search engine relies on the size of its indexed web pages and its ability to deliver accurate results. By the end of the 1990s, search engines were processing millions of searches daily, significantly impacting businesses that sought to enhance their visibility through search engine optimization. As search engines continue to evolve, they play a crucial role in daily life, shaping how information is accessed and influencing how content is structured online. The phrase "Google it" has become synonymous with searching for information, highlighting the deep integration of search technology into contemporary society.

Search engines
The World Wide Web contains billions of items of information located on its millions of sites. With the development of search engines in the 1990s, web users were able to locate quickly the information they queried. Becoming indispensable to web use, search engines contributed to the cachet and soaring stock prices of internet-related companies and became the primary method for finding information quickly in the twenty-first century.
Various kinds of search engines retrieve data from computers, but it was the emergence of efficient web search engines in the mid-1990s that helped make the resources of the internet widely available.
The internet is the worldwide network of interconnected computers. The web is the collection of billions of pages containing information in standardized interface that can be accessed on the internet through web browsers. In 1990, the first search engine, Archie, was developed at McGill University, retrieving information from the then three hundred thousand internet hosts. It was soon followed by rivals Veronica, Jughead, and Gopher. With the release of the web to the public in 1991, a new generation of efficient search engines was developed that used “indexes” (the engine’s catalog of web pages), “spiders” (programs that searched the Web to add pages to the index), and “relevancy software” that ranked retrieved pages for their match to the query. To use a search engine, the user formulates a search query, usually based on a combination of terms (Boolean) or natural language. The search engine instantly combs through billions of web pages to retrieve those that match the search criteria. The success of a search engine depends largely on the number of web pages in its index and its algorithms for generating the most relevant search results.
The launching of the search engine Excite in 1993 represented a breakthrough with Excite’s innovative statistical analysis of word relationships. The year 1994 saw the birth of Yahoo!, which included a directory classifying websites by subject category. Lycos (1994) pioneered the ranking of documents by relevance. Infoseek (1994) and AltaVista (1995) were metasearch engines, combining the results of individual search engines; AltaVista also offered a translation service and a search capability for sound and image files. Inktomi (1996) impressed with large-scale search capability made possible by using distributed network technology. Ask Jeeves (1997), later Ask, allowed for search queries in everyday language. Google, formed by two Stanford graduates in 1998, quickly became popular with its extensive search capabilities and such features as “cached,” which highlighted search terms in the document and displayed information from web pages that had expired. By decade-end, search engines were processing tens of millions of searches daily, utilizing billions of indexed pages. With the dot-com bubble, search engine companies skyrocketed in stock price and status.
Search engines continued to prove crucial in the early twenty-first century as people began to rely more and more upon the internet for daily life and business needs. As of 2024, Google remained one of the most popular throughout the world, with the phrase "Google it" having become synonymous with finding information on the internet. Other companies launched competing search engines as well, including Microsoft's Bing, which was first rolled out in 2009, and each version aimed to include the best features and technology (such as the ability to recognize human speech) to attract users with the most efficient and accurate results. In marketing, search engine optimization, or increasing traffic to a website by ensuring that it ranks high on the list of results returned by a search engine, became a primary concern, particularly for businesses.
Impact
The emergence of increasingly powerful search engines in the 1990s made vast resources of human intelligence available to any inquiry. Whatever fame and profit search engine companies achieved were a small reflection of the precise access to web information that search engines made possible.
