About robots.txt Generation

robots.txt is a plain text file at the root of a website that tells crawlers which paths they may visit and which they should avoid. The format dates to 1994 and is supported by virtually every search engine and well-behaved crawler. The file is advisory — malicious crawlers ignore it — but legitimate crawlers (Google, Bing, etc.) honor its directives reliably.

Common uses: blocking crawlers from admin areas (/wp-admin/, /admin/), excluding faceted search URL parameters that produce duplicate content, preventing indexing of staging or development paths, declaring sitemap location, and allowing specific user agents while blocking others. The file is read at the start of each crawl session.

This generator builds a syntactically correct robots.txt from form inputs. Common patterns (allow all, block all, block specific paths) are templates; custom rules can be added per user agent. The output goes at /robots.txt of your site root.

Why Use a robots.txt Generator

Hand-writing robots.txt is error-prone. Syntax mistakes (case sensitivity, exact path matching, ordering of rules) silently produce wrong behavior — paths you meant to block remain crawled, or paths you wanted indexed get excluded. A generator that produces correct syntax avoids these pitfalls.

robots.txt also has subtle interactions with other SEO tools. Disallowing a path in robots.txt does not prevent it from appearing in search results (Google may index the URL without crawling it); meta noindex requires the page to be crawled first. Knowing which tool to use for which intent matters; the generator can guide you.

How to Generate robots.txt

Pick a template, customize, deploy.

  1. Choose a starting template: Allow all (default crawl-everything posture), Block all (block everything from indexing), or Custom (start from rules you specify).
  2. Add user agent rules: Disallow specific paths for all crawlers, or for specific named bots (Googlebot, Bingbot, GPTBot). Each user agent block has its own set of Allow and Disallow directives.
  3. Add sitemap URL: Include the absolute URL of your XML sitemap. Crawlers use this to discover URLs they might miss otherwise.
  4. Save and deploy: Download the generated file. Upload to the root of your domain (so it appears at https://example.com/robots.txt). Verify by visiting that URL in a browser.

Common Use Cases

Technical Details

Format: User-agent: <name> followed by Allow/Disallow directives. * matches all bots. Specific names (Googlebot, Bingbot) target specific crawlers. Multiple User-agent blocks can stack rules.

Disallow: <path> blocks paths starting with the given prefix. Disallow: / blocks the entire site. Disallow: /admin/ blocks anything under /admin/. Trailing slash matters; Disallow: /admin (no slash) also matches /administrator.

Crawl-delay (in seconds) requests slower crawling. Sitemap (absolute URL) declares your sitemap location. # starts a comment line.

Best Practices

Frequently Asked Questions

Where do I put robots.txt?
At the root of your domain: https://example.com/robots.txt. Subdirectories don't work; only the file at the root is checked.
Does Disallow prevent indexing?
No. Disallow prevents crawling, but Google can still index URLs based on other signals (links from other sites). To prevent indexing, allow crawling and use a noindex meta tag.
Should I block AI crawlers?
A policy decision. Some site owners want their content excluded from AI training (block GPTBot, ClaudeBot, etc.); others welcome inclusion. The generator supports either approach.
Are wildcards supported?
Yes for specific patterns. * matches any sequence; $ matches end of URL. Disallow: /*.pdf$ blocks all PDF URLs.
How do I block one bot but allow others?
Separate User-agent blocks. User-agent: BadBot followed by Disallow: / blocks BadBot. User-agent: * with Allow: / allows others.
Is robots.txt case-sensitive?
Path matching is case-sensitive. Disallow: /Admin does not match /admin. Match the actual case of your URLs.
Does Crawl-delay actually slow Google?
Google does not honor Crawl-delay. It honors crawl rate settings in Search Console. Other crawlers (Bing, Yandex) respect Crawl-delay.
Is my data uploaded?
No. Generation happens in your browser.
