Search engines work by retrieving information from HTML markup of web pages and storing them. An automated web crawler, also referred to as a spider, is made use of for this purpose. The web crawler follows each and every link on the website. However, website owners can use robots.txt to exclude specific pages.

Search engines analyse the contents of web pages using algorithms and index them by extracting words from titles, headings, content and special fields known as meta tags. The data about web pages are collected and stored in a database. This data is made use of when Internet user types in queries on the search boxes provided on browsers.

The searching task is performed when a user types in terms or phrases containing the keywords into the search box. The search engine examines the index that it has created and then provides a list of web pages that match best with the specified criteria. Typically, the title of the webpage and a short summary of the content are also provided in the listing.
