Index

What is the Index in the Context of Search Engines?

The index of a search engine, such as Google, is a vast database where information about crawled web pages is stored. When a page is indexed, it has been visited and analyzed by search engine crawlers, and relevant information has been stored in the index to be displayed in response to relevant search queries.

Why is the Index Important?

Only pages included in a search engine's index can appear in the search results of that search engine. Therefore, website operators generally aim to have their pages represented in the index to be discoverable. However, there are instances where it is strategically beneficial to deliberately keep certain pages out of the index, such as in the case of duplicate content.
