Index
Also called: Spidering or Crawling
The term indexing refers to the process by which the spider of a search engine (such as Google) visits a Web page to form an image about its content. This indexing takes place by contributing to the search engine's goal of making its search results as relevant as possible. This is only possible if the search engine "knows" what content can be found on a given Web page. It is extremely important for the findability of a website(search engine optimization) that all pages of a website are properly indexed. This is easy to check by entering a website's domain name in the search engine's search bar with the word "site" in front of it. All indexed pages of a specific website will then be displayed as search results.
Indexing web pages
Indexing Web pages is an automated process. Google' s spiders (also called crawlers or bots) work according to an automated script. All the data that is indexed is stored in a large database. The websites that are highly regarded by the search engine (i.e., those that are frequently visited) will be visited more often by the crawlers. Therefore, these pages appear almost immediately in the search results. For less visited websites, this process may take a bit longer. Setting up a sitemap through Google Search Console can ensure faster indexing. Any links to a new page can also help this process.
