internet bots, also known as web robots, WWW robots or simply bots, are software applications that run automated tasks over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone. The largest use of bots is in web spidering, in which an automated script fetches, analyzes and files information from web servers. Bots may also be implemented where a response speed faster than that of humans is required (e.g., video gaming bots and auction-site robots) or less commonly in situations where the emulation of human activity is required, for example chat bots. Recently bots have been used for search advertising, such as Google AdSense.
