Indexing is a data that Google stores when it finds new pages or subpages. In particular, the index describes the content of the website based on the keyword, the relevant details and the location of the website, is the URL.

Google searches by following the links on the page, reading the sitemap you provided and in many other ways. These data collection processes are carried out by automated software, often called by name Googlebot, Google Spider or Google crawler.


Based on the links, the bot will decrypt the site's data and then store it in a huge database to return results when a user searches. To make billions of billions of Web pages fast in such a short time, companies such as Google, Bing, Yahoo ... have built data centers around the world. .
