Robots.txt is a standard used in web development that serves as a guideline for web robots, usually search engine^[2] crawlers, navigating a website^[4]. Proposed by Martijn Koster in 1994, it functions as a communication tool, asking robots to avoid specific files or sections of the website. This file is placed at the root of a website and is particularly important to search engine optimization^[1] (SEO) strategies as it helps control what parts of the site are indexed. While there is no legal or technical enforcement mechanism, compliance with this standard is crucial for efficient and secure website crawling. It's noteworthy that the standard has evolved over time, with updates reflecting changing webmaster^[3] needs, and that understanding its nuances is imperative for effective SEO.

Terms definitions

1. ↑ search engine optimization. Search engine optimization, commonly referred to as SEO, is a critical digital marketing strategy. Originating in the mid-90s, SEO involves enhancing websites to achieve higher rankings on search engine results pages. This process is essential for increasing web traffic and converting visitors into customers. SEO employs various techniques, including page design, keyword optimization, and content updates, to enhance a website's visibility. It also involves the use of tools for monitoring and adapting to search engine updates. SEO practices range from ethical 'white hat' methods to the disapproved 'black hat' techniques, with 'grey hat' straddling both. While SEO isn't suitable for all websites, its effectiveness in internet marketing campaigns cannot be underestimated. Recent industry trends such as mobile web usage surpassing desktop usage highlight the evolving landscape of SEO.

2. ↑ search engine. A search engine is a vital tool that functions as part of a distributed computing system. It's a software system that responds to user queries by providing a list of hyperlinks, summaries, and images. It utilizes a complex indexing system, which is continuously updated by web crawlers that mine data from web servers. Some content, however, remains inaccessible to these crawlers. The speed and efficiency of a search engine are highly dependent on its indexing system. Users interact with search engines via a web browser or app, inputting queries and receiving suggestions as they type. The results may be filtered to specific types, and the system can be accessed on various devices. This tool is significant as it allows users to navigate the vast web, find relevant content, and efficiently retrieve information.

robots.txt (Wikipedia)

robots.txt is the filename used for implementing the Robots Exclusion Protocol, a standard used by websites to indicate to visiting web crawlers and other web robots which portions of the website they are allowed to visit.

The standard, developed in 1994, relies on voluntary compliance. Malicious bots can use the file as a directory of which pages to visit, though standards bodies discourage countering this with security through obscurity. Some archival sites ignore robots.txt. The standard was used in the 1990s to mitigate server overload; in the 2020s many websites began denying bots that collect information for generative artificial intelligence.

The "robots.txt" file can be used in conjunction with sitemaps, another robot inclusion standard for websites.
