Search Engine Indexing

 Search engines are answer machines. They exist to discover, understand, and organize the internet's content in order to offer the most relevant results to the questions searchers are asking.

How Search Engines work - (specifically Google)

Search engines have three primary functions:

  • -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.

What is a search engine index?

Search engines process and store information they find in an index, a huge database of all the content they’ve discovered and deem good enough to serve up to searchers.
