Writing a robots.txt file manually is error-prone. A misplaced directive or forgotten crawler can make your entire site invisible to search engines or AI platforms. A robots.txt generator creates a properly formatted file based on your preferences, ensuring correct syntax and complete coverage. This is especially important in 2026, when your robots.txt needs to account for **over a dozen AI-specific crawlers** beyond traditional search bots. Each AI platform (ChatGPT, Claude, Perplexity, Gemini, Copilot) uses its own user-agent, and each requires explicit rules if you are using a restrictive default policy. Our generator creates a robots.txt file optimized for both [AI search visibility](/services/ai-search-seo) and traditional SEO, with toggles for AI crawlers, social media bots, crawl delays, and sitemap declarations. ## How to Use Your Generated Robots.txt 1. Configure your preferences using the toggles and inputs on the left. 2. Review the generated file in the preview panel on the right. 3. Click "Copy" or "Download" to get the file. 4. Upload the file to your website's root directory (e.g., `yourdomain.com/robots.txt`). 5. Use our [Robots.txt Checker](/tools/robots-txt-checker) to validate the live file after deployment. ## Robots.txt Best Practices for Modern Websites What we configure for every client and recommend you do the same. 01 ### Start permissive, restrict selectively. The safest default is Allow: / under User-agent: \*. From there, add specific Disallow rules only for paths that genuinely need protection (admin panels, staging, internal APIs). The opposite approach, blocking everything and whitelisting, is fragile and guaranteed to break when someone adds a new page or directory. 02 ### Give every AI crawler its own block. GPTBot, ChatGPT-User, ClaudeBot, anthropic-ai, PerplexityBot, Google-Extended. Each one needs its own User-agent section with Allow: /. This is not optional in 2026. If you use a restrictive wildcard policy and forget to add an AI bot, that platform cannot see your content. Our generator handles this automatically. 03 ### Include social media bots for link previews. Twitterbot, facebookexternalhit, and LinkedInBot are not search crawlers. They render Open Graph previews when someone shares your link. If these are blocked, your shared links appear as blank cards with no title, image, or description. That kills click-through rates on social channels. 04 ### Add your sitemap URL. Every time. A Sitemap: directive at the bottom of robots.txt tells every crawler where to find your XML sitemap. It is the simplest line you can add and one of the most impactful. Do not assume crawlers will find it through other means. 05 ### Skip the crawl-delay unless you have a real reason. Crawl-delay is ignored by Google entirely. Bing respects it but you rarely need it. Setting a high delay slows indexing and does not meaningfully reduce server load on modern infrastructure. If your server struggles under crawler traffic, the problem is your server, not your robots.txt. 06 ### Version control your robots.txt. Treat robots.txt like code. Put it in Git. Review changes in pull requests. A one-line accidental edit can make your entire site invisible. If someone changes this file, you want a diff, a reviewer, and a deployment log. ## Robots.txt Mistakes That Cost Real Traffic We have seen every one of these. Tap to see what went wrong and how to fix it. CRITICAL ### Generating a file but never deploying it A marketing team generates a perfect robots.txt. It sits in a Google Doc. The live site still serves the old file. CRITICAL ### Blocking all bots by default, then forgetting to add exceptions Setting User-agent: \* Disallow: / as the default, intending to add Allow rules for specific bots. Then shipping it without the bot-specific blocks. WARNING ### Adding disallow paths that match real content Blocking /api/ seems reasonable. But if your marketing site uses /api-integrations/ or /api-security-guide/ as blog paths, those get blocked too. WARNING ### Not including the trailing slash on directories Writing Disallow: /admin instead of Disallow: /admin/ TIP ### Using crawl-delay when you do not need it Setting a 10-second crawl delay because someone read it was best practice. ## Frequently Asked Questions ### What should a robots.txt file include for AI search optimization? ### Where do I put my robots.txt file? ### Should I allow or block AI crawlers by default? ### What is the difference between Allow and Disallow in robots.txt? ### What is Crawl-delay and should I use it? ### Can I have different robots.txt files for different subdomains? ## Need Help With AI Search Visibility?
