This document discusses search engines, providing definitions and explaining their purpose, workings, history, and types. It defines a search engine as software that searches a database and gathers related information to specified search terms. It describes how search engines work by using bots to index web pages and how they return relevant results based on algorithms. The history outlines key early search engines from the 1990s like Archie and more recent developments in ranking algorithms and paid search advertising. In closing, it categorizes search engines as crawler-based, directories, hybrid, or meta search engines.

Search Engine is a complex
algorithm [computerized program]
These complex algorithms are
called as Spiders or Bots , who go
out hunting websites on the

- 7. Working of Search Engines Search Engine is a complex algorithm [computerized program] These complex algorithms are called as Spiders or Bots , who go out hunting websites on the internet.
- 8. Bots and Spiders find new websites and pages by following links added on a website. once a new page is found the spider or bot reads the Content & also checks for Images.
- 9. everything is stored in a huge online library called as “Index”. This indexed data is stored in encoded Format to save space
- 10. A user types query on search engine search bar The search engine goes back to its mammoth index library to fetch the required information. The search engine found millions of matching information, so it uses an algorithm to decide in which order to display the results
- 11. Information is ready in less than 1 second and displayed on a SERP [Search Engine Result Page] Regularly updated websites with unique content are given better positions on SERP. User analyzes the search result and reaches a website.
- 12. History of Search Engine 1990 - The first search engine Archie was released . There was no World Wide Web at the time. The computers were interconnected by Telenet. File Transfer Protocol (FTP) used for transferring files from computer to computer. There was no such thing as a browser.
- 13. Files were transferred in their native format and viewed using the associated file type software. Archie searched FTP servers and indexed their files into a searchable directory.
- 14. 1994 - WebCrawler, a new type of search engine that indexed the entire content of a web page , was introduced. Telenet / FTP passed information among the new web browsers accessing not FTP sites but WWW sites. Webmasters and web site owners begin submitting sites for inclusion in the growing number of web directories.
- 15. 1995 -Meta tags in the web page were first utilized by some search engines to determine relevancy. 1997 - Search engine rank-checking software was introduced. It provides an automated tool to determine web site position and ranking within the major search engines. 1998 - Search engine algorithms begin incorporating esoteric information in their ranking algorithms.
- 16. 2000 - Marketers determined that pay-per click campaigns were an easy yet expensive approach to gaining top search rankings. To elevate sites in the search engine rankings web sites started adding useful and relevant content while optimizing their web pages for each specific search engine.
- 17. Types of Search Engines On the basis of working, Search engine is categories in following group -Crawler-Based Search Engines -Directories -Hybrid Search Engines -Meta Search Engines
