Robots.txt Generator — Control How Search Engines Crawl Your Site

Create a clean, standards-compliant robots.txt in seconds. Add allow and disallow rules per user-agent, point crawlers at your sitemap, set a host and crawl delay, and download a file ready to drop into your site root.

The generator validates the syntax as you build, so you never accidentally block your entire site. It's the fastest way to control what Google and other bots can crawl — right in your browser.

  • Allow & Disallow rules
  • Sitemap + Host directives
  • Crawl-delay support
  • Syntax validation

Why Use Robots.txt Generator?

Visual Rule Builder

Add and reorder allow/disallow rules without remembering robots.txt syntax.

Sitemap & Host Directives

Automatically add Sitemap: and Host: lines to help crawlers discover your content.

Crawl-Delay Support

Set a crawl delay for bots that respect it, like Bing and Yandex.

Syntax Validation

Real-time checks warn you about malformed rules before you publish.

Features

Multiple User-Agents

Separate rule sets for Googlebot, Bingbot, and * (all bots) with independent allow/disallow rules.

Allow & Disallow

Add precise path rules — disallow /admin/, allow /public/, and everything in between.

Sitemap Directive

One click adds your sitemap URL so search engines find it from the root file.

Host & Crawl Delay

Optional Host: and Crawl-delay: lines for complete control over crawling behavior.

Live Syntax Check

Invalid paths or duplicate groups are flagged immediately with a validation summary.

Copy & Download

Copy the file with one click or download robots.txt ready to upload to your site root.

How to Generate a Robots.txt

Build a crawler-friendly robots.txt in three quick steps.

1

Add user agents

Create rule groups for Googlebot, Bingbot, or * — or just use the default group for all bots.

2

Set allow & disallow rules

Add paths you want to block (like /admin or /cart) and paths you want to explicitly allow.

3

Add sitemap & download

Enter your sitemap URL, review the live preview, and copy or download the file to your site root.

Frequently Asked Questions

Got questions? We've got answers.

What is a robots.txt file?

robots.txt is a plain-text file in your site root that tells search engine crawlers which URLs they may or may not crawl.

Where do I put my robots.txt file?

Upload it to the root of your domain, e.g. https://yoursite.com/robots.txt. Next.js serves it automatically from app/robots.ts.

Does robots.txt block indexing?

No — robots.txt only controls crawling, not indexing. To remove a page from search results entirely, use a noindex meta tag or header.

What does Disallow: / mean?

Disallow: / tells all bots not to crawl any part of the site. Only use it if you truly want to block crawling site-wide.

Do I need to list Googlebot separately?

The * group covers all bots. Add a Googlebot group only when you need behavior specific to Google, like different crawl rules or no crawl delay.

What is a Sitemap: line?

A Sitemap: line points crawlers to your XML sitemap location. It's the standard way to submit sitemaps in robots.txt.

What is Crawl-delay?

Crawl-delay tells a bot how many seconds to wait between requests. Googlebot ignores it, but Bing and Yandex respect it.

Is the robots.txt generator free?

Yes, it's completely free with no sign-ups, no watermarks, and no usage limits.

Can I have rules for multiple bots?

Yes — create separate user-agent groups (Googlebot, Bingbot, etc.) each with their own allow and disallow rules.

What happens if I make a syntax error?

Crawlers ignore malformed rules, which can leave pages accidentally exposed or blocked. The generator validates syntax as you type to prevent this.

Does robots.txt affect SEO?

Indirectly — blocking important pages wastes crawl budget, while accidentally exposing private pages can hurt you. A correct file keeps crawling efficient.

Should I disallow /wp-admin or /admin?

Many sites disallow admin and backend paths to keep crawlers out. Just make sure the paths you block don't include resources your pages need.

Can robots.txt have comments?

Yes — lines starting with # are comments. Use them to document why each rule exists.

How do I test my robots.txt?

Use Google Search Console's robots.txt tester or the URL Inspection tool to see which rules apply to a specific URL.

Does the tool support a Host directive?

Yes — the optional Host: line (used mainly by Yandex) declares your preferred domain, and the generator adds it if you enable it.
