Search Engines

Web search engines work by sending out a spider to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Each search engine — like Google, Bing, Ask.com and others — use proprietary algorithms to crawl, index and display search results.

From understanding how Web and enterprise search engines work to search engine optimization (SEO) best practices, our search engine dictionary offers a glossary of important terms you need to know.
