Robots.txt Generator

Build your file on the left — the output updates live on the right.

Default crawler access

1. Default crawler access

2. Sitemaps & crawl delay

Google ignores this; Bing and Yandex honour it.

Your robots.txt

2 lines · 24 bytes

User-agent: *
Disallow:

No Sitemap line. Referencing your XML sitemap in robots.txt is the easiest crawl-discovery win — add one if you have a sitemap.

Upload the file to your domain root so it resolves at https://yourdomain.com/robots.txt, then test it in Google Search Console. Nothing you enter here leaves your browser.

Features

Everything you need for a correct robots.txt

Every capability below is fully functional, free, and available without an account. The tool follows the same robots exclusion protocol rules that Google, Bing, and modern AI crawlers actually implement.

Unlimited User-Agent Groups

Create separate rule groups for Googlebot, Bingbot, AI crawlers, or any custom bot — each with its own Allow and Disallow rules, exactly as the protocol intends.

AI Crawler Presets

One-click presets for GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, anthropic-ai, and OAI-SearchBot — control how AI systems use your content.

Common Path Presets

Insert typical disallow rules — /admin, /cart, /checkout, /wp-admin/, /*?*, /search, /tag/ — with one click, so sensible defaults take seconds, not research.

Live Output Preview

The robots.txt output rebuilds on every change in a clean monospace panel with live line count and byte size — what you see is exactly what you download.

Mistake Warnings

The tool flags dangerous patterns as you type: a full-site block under User-agent: *, rules that look like they block CSS/JS, duplicate groups, and a missing sitemap.

Sitemap Directives

Add one or more Sitemap: lines with URL validation, so every crawler that reads your robots.txt is pointed straight at your XML sitemap.

Crawl-Delay Control

Set an optional crawl delay for bots that honour it — with an honest note that Google ignores this directive, so you are never misled.

Copy or Download Instantly

Copy the finished file to your clipboard or download it as robots.txt, correctly named and typed, ready to upload to your site root.

Benefits

Why a well-built robots.txt matters for SEO

Protect your crawl budget

Search engines allocate a finite crawl budget per site. Keeping crawlers out of infinite URL spaces — faceted filters, internal search, calendar pages — leaves more budget for pages that should rank.

Keep low-value pages out of the crawl

Cart, checkout, admin, and thank-you pages add nothing to your search presence. Disallowing them keeps crawl activity focused on content that earns traffic.

Point every crawler at your sitemap

The Sitemap: line in robots.txt is the one place every crawler looks first. Referencing your XML sitemap there speeds up discovery of new and updated pages.

Decide how AI crawlers use your content

GPTBot, ClaudeBot, PerplexityBot, and Google-Extended each respect robots.txt. Whether you welcome AI training and answer engines or opt out, the choice should be yours — deliberately.

Avoid accidental catastrophes

A stray Disallow: / left over from staging can wipe a site out of search for weeks. Building the file in a tool that warns about exactly that pattern is cheap insurance.

Free, private, and instant

No account, no upload, no server round-trips. The file is built in your browser as you type, and you leave with a correct, valid robots.txt in under a minute.

About This Tool

What is robots.txt — and why generate it with a tool?

robots.txt is the first file a search engine requests from your site. It lives at your domain root and tells crawlers — Googlebot, Bingbot, and increasingly AI crawlers like GPTBot and ClaudeBot — which paths they may crawl, which they should skip, and where your XML sitemap lives. The syntax looks trivial: a few User-agent, Allow, and Disallow lines. But the rules of interpretation are not. Crawlers follow only the most specific matching group, the longest matching rule wins conflicts, and one character in the wrong place can quietly block your entire site from search.

That is why hand-typing robots.txt is riskier than it looks. The classic failure is a leftover Disallow: / from a staging server reaching production — traffic then decays for weeks before anyone notices. Other common mistakes are subtler: blocking CSS and JavaScript folders (which breaks Google's page rendering), using Disallow to try to de-index a page (it does the opposite), or duplicating user-agent groups so crawlers pick one and ignore the rest. This generator builds the file interactively, validates sitemap URLs, and warns about each of those patterns live, before you download anything.

The tool was built by the SEO team at CV Infotech — the same people who configure crawl rules for client sites in WordPress, Shopify, and custom builds every week — using the React and TypeScript stack our web development team ships to clients. It is free, requires no account, and nothing you type is sent to any server. If your crawl problems go deeper than one file — index bloat, crawl budget waste, or a migration gone wrong — that is work we do for clients every day.

Step-by-Step Guide

How to generate your robots.txt in five steps

Choose a default access preset

Start from 'Allow all', 'Block all', or 'Custom'. Most public sites start from Allow all and add targeted Disallow rules for paths that should stay out of the crawl.

Add user-agent groups and rules

Keep the * group for all crawlers, or add groups for specific bots — including AI crawlers — and give each its own Allow and Disallow paths. Use the one-click path presets for common rules.

Add your sitemap URL

Paste the full absolute URL of your XML sitemap (or several). This is the single most valuable line in the file for search visibility.

Review the live output and warnings

Check the generated file in the output panel. Resolve any warnings — especially a full-site block — before you ship it.

Upload to your site root and test

Download robots.txt, upload it to your domain root so it resolves at /robots.txt, then verify it in Google Search Console's robots.txt report before considering the job done.

Use Cases

Who needs a robots.txt generator?

WordPress & WooCommerce Sites

Keep /wp-admin/ out of the crawl (while allowing admin-ajax.php), block internal search and tag archives, and point crawlers at the sitemap your SEO plugin generates.

Shopify Stores

Supplement Shopify's default robots handling — decide policy for AI crawlers, and document sitemap locations for additional storefront domains.

Staging vs Production

Generate a strict Block-all file for staging environments and a clean production file — and never again ship the staging file to production by accident.

Large eCommerce Catalogues

Faceted navigation can generate millions of parameter URLs. Disallowing /*?* patterns and filter paths protects crawl budget for category and product pages that actually rank.

Controlling AI Crawler Access

Publishers and businesses deciding whether GPTBot, ClaudeBot, or Perplexity may use their content can express that policy in one place, per crawler, in minutes.

Agencies Managing Client Sites

Produce a correct, documented robots.txt for every client launch or migration checklist item — consistent, reviewable, and free of hand-typed syntax errors.

Best Practices

Robots.txt best practices that protect your rankings

One robots.txt, at the domain root

Crawlers only request /robots.txt from the root of each host. One file per subdomain, always at the root, always plain text encoded as UTF-8.

Always reference your XML sitemap

Add a Sitemap: line with the absolute URL. It is the cheapest crawl-discovery win available and works for every search engine at once.

Never block CSS and JavaScript

Google renders your pages. If it cannot fetch assets, it cannot evaluate the page properly — mobile-friendliness and rankings suffer. Leave asset folders crawlable.

Use noindex for de-indexing, not Disallow

Disallow stops crawling; it does not remove pages from results. To de-index, allow the crawl and add a noindex meta tag or X-Robots-Tag header.

Test before and after deploying

Run the file through Google Search Console's robots.txt report. One character in the wrong place can block your whole site — verify, do not assume.

Keep it minimal

Every rule is a chance to make a mistake. Block what genuinely needs blocking, reference the sitemap, and stop. Short files are correct files.

Watch Out

Common robots.txt mistakes to avoid

Disallow: / left over from staging

The classic site-killer: the pre-launch block-all file goes live with the site. Traffic drops to zero over days. This tool shows a prominent warning whenever a full-site block is present under User-agent: *.

Blocking CSS and JS folders

Breaks Google's page rendering, so it cannot see your site the way users do. An old habit from the 2000s that now actively hurts rankings.

Assuming Disallow removes pages from Google

It does not — it only stops crawling. Disallowed pages can still be indexed from external links, and Google can never see a noindex tag on a page it is not allowed to fetch.

Wrong file location

A robots.txt in /blog/robots.txt or a subfolder does nothing. It must be at the domain root, one file per subdomain and protocol.

Using robots.txt to hide private data

robots.txt is public — anyone can read it, and listing /secret-admin/ in it is literally a signpost. Sensitive areas need authentication, not a crawl directive.

Conflicting rules across groups

Crawlers follow only the most specific matching user-agent group — a Googlebot group completely replaces the * group for Googlebot; the two are not merged. Duplicate groups for the same agent make behaviour unpredictable.

FAQ

Robots.txt generator — frequently asked questions

robots.txt is a plain-text file that tells search engine crawlers which parts of your website they may or may not crawl. It uses simple directives — User-agent, Allow, Disallow, Crawl-delay, and Sitemap — grouped by crawler. It is a crawl directive, not a security mechanism: well-behaved bots follow it, but it does not password-protect anything.
