Robots.txt -To put it simply, this is a set of instructions for bots. This file is included in the source files of most websites. Robots.txt files are mainly intended to control the actions of good bots, such as web crawlers since bad bots are unlikely to follow instructions.
Think about robots.txt For example, a "code of conduct" sign posted on a wall in a gym, bar, or community center: the sign itself does not have the power to enforce the listed rules, but "good" visitors will follow the rules, while "bad" ones are more likely to violate them and get banned.
In other words, it is an automated computer program that interacts with websites and applications. There are good bots and bad bots, and one type of good bot is called a web crawler bot. These bots "crawl" web pages and index the content so that it can be displayed in search results. A robots.txt The file helps manage the activities of these web crawlers so that they do not overload the web server hosting the website or index pages that are not intended for public viewing.
