Robot.txt Generator

🤖 Robots.txt Pro Studio

Generate, test, simulate Googlebot with fixed parser, correct pattern matching (*, $), and real specificity priority. Upload existing files, add Allow/Disallow rules, and see exactly how Google decides.

⚙️ Build your robots.txt

🌐 Default rule for * (all bots) ✅ Allow all (Disallow: empty) ⛔ Block all (Disallow: /)

⏱️ Crawl-delay (seconds) No delay 5 sec 10 sec 30 sec

⚠️ Google ignores crawl-delay, but Bing/Yandex respect it.

🗺️ Sitemap URL

🤖 Specific bots (select multiple) Googlebot Bingbot Yahoo Slurp DuckDuckBot Baiduspider

📝 Custom Allow / Disallow rules (supports *, $)

🚫 Disallow ✅ Allow

Use * for wildcard, $ for end-of-URL matching. Example: /private/*.pdf$ blocks all PDFs in /private/

🔍 Real-time Validation & Googlebot Simulator (Fixed)

🤖 Test a URL against current robots.txt (Googlebot algorithm)

✅ Fixed: Exact user-agent priority (Googlebot block overrides *). Most specific pattern wins (longest literal length). Tie → last rule in block. Supports * and $.

✨ Why this tool is different

✅ Advantages
• Allow/Block UI with wildcards
• Upload & test existing files
• Googlebot simulator with correct specificity
• Real-time syntax checking
• Export .txt or .json

🎯 Why use it?
Most tools get priority wrong. Our parser follows Google's official logic: exact user-agent match, longest pattern wins, last rule on tie. No guesswork.

📊 vs other tools
Others: broken pattern matching, wrong rule order, ignore specificity. Ours: fully compliant with Google's robots.txt spec.

❓ Frequently Asked Questions

How does rule priority work exactly? ➕

Google uses the most specific matching rule: the one with the longest literal pattern length. If two rules have the same length, the last one in the block wins. Also, a dedicated "User-agent: Googlebot" block overrides the "*" block entirely.

What wildcards are supported? ➕

* matches any sequence (including empty). $ anchors the pattern to the end of the URL. Example: "/private/*.pdf$" blocks only PDFs ending in /private/.

Can I upload my existing robots.txt? ➕

Yes! Click the upload zone, pick your file. The tool parses it correctly (handles comments, multiple user-agents) and shows you exactly how Googlebot would evaluate any URL.

Why did my previous tool give a different result? ➕

Most free tools do not implement the specificity algorithm. They just check first match or ignore pattern length. Our simulator is accurate to Google's documentation.
