Web Crawler Search Engine: How It Works and Why You Should Use It?
If you are looking for a fast, simple, and comprehensive way to find information on the web, you might want to try Webcrawler. Webcrawler is one of the earliest search engines still in use today. It was the first web search engine to provide full-text search, meaning that it indexed every word on every web page, rather than just the titles and meta tags. It was also one of the first search engines to use a crawler or a program that automatically visits web pages and follows links to discover new content.
Today, Webcrawler is a metasearch engine that aggregates results from multiple sources, such as Google, Yahoo, Bing, and others. It also features news, images, videos, maps, and shopping results. Webcrawler claims to respect user privacy and does not collect or share personal information. Webcrawler also offers click fraud protection software, which helps advertisers detect and prevent fraudulent clicks on their online ads.
History of WebCrawler
Webcrawler was created by Brian Pinkerton in 1994 as a personal project. He was interested in finding information on the web, but he was frustrated by the existing search tools at that time. Most of them were either directories or indexes that only searched for keywords in the titles or meta tags of web pages. They also had limited coverage and often returned outdated or irrelevant results.
Pinkerton decided to create his own search engine that would index every word on every web page. He wrote a crawler program that would visit web pages and follow links to discover new content. He also wrote an indexer program that would store the words and their locations in a database. He then wrote a query processor that would match user queries with the indexed words and rank the results by relevance.
Pinkerton named his search engine Webcrawler after the crawler program he wrote. He launched it on April 20, 1994, from his dorm room at the University of Washington. He initially used his personal computer as the server, but soon he had to upgrade to a larger machine due to the increasing traffic. He also had to rent more disk space from other servers to store the growing index.
Webcrawler was an instant hit among web users and developers. It was praised for its speed, accuracy, and comprehensiveness. It was also featured in several media outlets such as Wired, CNN, and The New York Times. Webcrawler soon became one of the most popular search engines on the web.
Webcrawler also attracted the attention of several investors and partners who wanted to acquire or collaborate with Pinkerton. In June 1995, Webcrawler was acquired by America Online (AOL), which integrated it with its online service. AOL provided more resources and support for Webcrawler but also imposed some restrictions on its development and operation.
In April 1997, Webcrawler was sold to Excite, another web portal and search engine that competed with AOL. Excite merged Webcrawler with its own search technology and brand name. Excite also added more features and services to Webcrawler, such as email, chat rooms, games, news, weather, sports, etc.
In January 2001, Excite filed for bankruptcy due to financial difficulties caused by the dot-com bubble burst. Webcrawler was acquired by InfoSpace, which also owned other search engines such as Dogpile and MetaCrawler. InfoSpace rebranded Web crawler as a metasearch engine that would aggregate results from multiple sources such as Google
