The Robots Exclusion Protocol (REP) is a standard used by websites to communicate with web crawlers and search engine bots. A well-crafted robots.txt file dictates which URLs can be accessed by automated spiders.
Core Syntax and Directives
Every robots.txt file consists of user-agents followed by allow or disallow directives. For example, to prevent aggressive scraping of sensitive endpoints:
User-agent: *
Disallow: /api/
Disallow: /private/
Sitemap: https://whoisy.online/sitemap.xmlSecurity Warning
Never rely on robots.txt to secure confidential data. Malicious scrapers routinely ignore disallow rules.
