# robots.txt generated by Zonified Free SEO Tools # Domain: https://example.com User-agent: * Disallow: /admin/ Disallow: /checkout/ Disallow: /search Allow: / User-agent: PerplexityBot Allow: / User-agent: ChatGPT-User Allow: / Sitemap: https://example.com/sitemap.xml
Important: Robots.txt is an advisory protocol, not a security mechanism. Never use it to hide sensitive data.
How to Use Free Robots.txt Generator
Enter your website domain and XML sitemap URL into the configuration panel above. Use the interactive rule manager to add allow or disallow paths for specific user-agents (such as Googlebot, Bingbot, or wildcard *). Toggle specialized AI crawler settings to either allow generative search engines (like Perplexity and SearchGPT) or disallow AI model training scrapers (like GPTBot and CCBot). The tool generates syntactically validated robots.txt directives in real time, alerting you to potential path conflicts or trailing slash mistakes. You can copy the code immediately or download a clean robots.txt file to upload to your web root.
Configure Sitemaps
Provide your primary XML sitemap URL so crawlers discover all pages.
Define Path Rules
Add disallow directives for private sections (e.g., /admin/, /checkout/).
Download File
Verify clean syntax in the live preview and download your robots.txt file.
Why a Properly Configured Robots.txt Matters
Your robots.txt file is the foundational traffic controller for your website. Misconfigured crawl rules can lead to devastating SEO disasters—such as blocking your entire site with an accidental 'Disallow: /' or preventing Googlebot from rendering JavaScript and CSS stylesheets necessary for mobile indexing. Conversely, a clean robots.txt directs search engines away from low-value faceted navigation, internal search results, and admin panels, preserving valuable crawl budget for high-converting content and product pages.
