CRAWL: Scour the Internet for content, looking over the code/content for each URL they find.
INDEX: Store and organize the content found during the crawling process. Once a page is in the index, it’s in the running to be displayed as a result to relevant queries.
RANK : Provide the pieces of content that will best answer a searcher's query, which means that results are ordered by most relevant to least relevant.
