Mechanisms that are generally known as the bots or spiders generally crawl the Web looking for new pages.
The bots are known to typically start with a list of the website URLs that are determined from the previous crawls. Whenever they generally detect new links on these pages with the help of tags like HREF and SRC, they are known to add these to the list of sites to index.
