Bot’s/robots/spiders/crawlers is aa automated application designed to systematically browse and index content on the internet. These bots are essential components of smajor search engines. Their primary function is to discover new web pages and gather information about existing ones.
When a bot visits a website, it follows links from one page to another while analysing various elements such as text content, images, metadata, and site structure. This process enables search engines to create an index. The quality of the indexing directly influences how well a site ranks in search engine results pages (SERPs).
Bots operate continuously across the web they can visit thousands or millions of sites daily without human intervention. They adhere to protocols defined by the robots.txt file found on each website which indicates which parts of the site should not be crawled or indexed.
