Search Engines are system softwares designed to search the web for various facts, images, videos, and other media. Search Engines go back to World War II when the idea of "a virtually limitless, fast, reliable, extensible, associable memory storage and retrieval system was established by Vannevar Bush (*4).Search engines consist of three parts: spiders that follow links and searhc the web, an index or catalog that represents the content of the web, and searhc interface relevancy software (*4). As times have continued to change, search engines are fighting for market share and companies and organizatons are using search engines for marketing to their consumers. Though search engines are instrumental in today's world, there are still concerns associated with them. Privacy, publishing, and copyright lawsuits are common regarding the content and conduct of search engines and the companies who own/run them.
The major search engine in today's times is Google. Google has a 92.74% market share as of October 2018, handling more than 3.5 billion searches per day (*3). Google Search is considered the most popular search engine. Alternative search engines include Bing, DuckDuckGo, and Yahoo! Search. Bing is the third largest search engine globally with a query volume of 4.58% (*1). DuckDuckGo has less than 1% market share (*5), but in March 2019, had over 36 million daily direct searches on average (*2).
According to Search Enginge Market Share, Google accounts for 88.5% of the market, Bing accounts ofr 6.12%, Yahoo! accounts for 4.11%, and DuckDuckGo accounts for 0.99% as of March 2019. All of these search engines are quite popular and are used frequently as the data illustrates. The question remains: how have these search engines remained on top for so many years?
