Free Robots.txt Generator Online — Create a Safe File in 3 Steps
Create a robots.txt file without memorizing crawler syntax. Choose your website type, add a sitemap if you have one, and decide whether to add selected AI/model-training crawler controls. This free robots.txt generator builds a clean draft you can review, copy, and download, while advanced settings stay out of the way until you actually need them.
A robots.txt file is a small plain-text file that sits at the root of a website and gives compliant web crawlers instructions about which URL paths they may request. Search engines such as Google use these rules while crawling, and many AI-related crawlers also publish their own robots.txt product tokens. The file is simple to read, but a single broad rule can affect thousands of URLs, which is why manually typing one without checking the result can be risky.
This free robots.txt generator online is designed for website owners who want a safer starting point without
turning a basic task into a technical SEO project. You choose the type of site you run, optionally add your XML sitemap, choose
whether you want selected model-training crawler controls, and the tool creates a downloadable robots.txt draft.
If you are an SEO professional or developer, the Advanced Options section still gives you custom
User-agent, Allow, Disallow, crawler-specific and crawl-delay controls.
Why use a generator at all? It reduces syntax mistakes, makes high-impact rules easier to spot, gives beginners conservative defaults, and lets you review the actual file before it goes live. It can also save time when you need to create separate rules for search crawlers and model-training controls. Robots.txt is still a crawl-control file, not a security system or a guaranteed way to remove pages from search results. If your goal is to keep a page out of Google, use an appropriate indexing or access-control method instead.
Robots.txt Generator
Most users only need the three choices below. Open Advanced Options only when your site needs custom crawl rules.
Choose your website type
This selects a conservative starting file. You should still review it before publishing.
Add your sitemap URL (optional)
If you already have an XML sitemap, you can declare its absolute URL in the generated file.
AI/model-training crawler preference (optional)
Leave this off if you do not want to add any model-training opt-out rules.
Disallow: / for GPTBot, ClaudeBot and Google-Extended. It does not block OpenAI's OAI-SearchBot or Anthropic's search/user retrieval bots.
Search & user-retrieval crawlers
Google AdSense Publisher Controls
Useful for AdSense publishers who want their robots.txt file to state ad-crawler access explicitly.
Avoid Disallow: / for these crawlers when you want Google advertising crawlers to access eligible pages.
Optional Anthropic crawl-delay
Non-standard: Crawl-delay is not part of RFC 9309 and Google does not support it. Anthropic currently documents support for Crawl-delay on its bots, so this setting is kept crawler-specific instead of applying it to every crawler.
Custom Allow / Disallow rules
Only add rules for paths you understand. A wrong Disallow: / can stop compliant crawlers from crawling your site.
Existing robots.txt Quick Check
Already have a file? Paste it here for a local structural review of common issues. This is a quick checker, not a full crawler emulator or substitute for testing the live file in Search Console.
🔒 Configuration processing is local: the robots.txt text is created in your browser. The surrounding webpage may still make normal requests for site assets, analytics, consent tools, or advertising.
Why Use This Free Robots.txt Generator Instead of Typing the File Manually?
Robots.txt syntax looks short, which can make it feel harmless. In practice, the difficult part is not typing
User-agent or Disallow; it is understanding what a rule will affect and avoiding a configuration that
blocks more than you intended. This generator focuses on that decision-making process rather than overwhelming you with dozens
of options on the first screen.
Beginner-first setup
Start with General Website, WordPress, Blog/Blogger, or E-commerce and get a conservative draft instead of a long list of guessed paths.
Safer defaults
The tool avoids automatically blocking common folders just because another website or CMS uses them. You add restrictions only when they make sense for your own site.
AI crawler controls without mixing purposes
Model-training controls are kept separate from search and user-retrieval crawlers so you can make a more deliberate choice.
Review before download
Your generated text and high-impact warnings are visible before you copy or download the file, making accidental site-wide blocks easier to catch.
The result is still a draft, because no online robots.txt maker can know your complete URL structure, CMS configuration, plugins, storefront routes, private application paths, or business requirements. The safest workflow is: generate → review → publish → test the live file.
How to Create a Robots.txt File Online in 4 Simple Steps
You do not need to understand every crawler directive before creating a useful robots.txt file. Start with the smallest configuration that matches your real need, review the generated draft, and add advanced rules only when you know what the path or crawler token is meant to control.
https://example.com, the file is normally served as
https://example.com/robots.txt. A robots.txt file applies to the protocol and host where it is served.
Who Should Use a Robots.txt Generator?
This tool is useful whenever you need crawler rules but do not want to hand-build the file from scratch. The simple mode is aimed at ordinary site owners, while Advanced Options keeps enough control for technical users.
Website owners and bloggers
Create a basic robots.txt draft, add a sitemap, and understand what the file is doing before you publish it.
WordPress users
Use a conservative WordPress robots.txt starting point instead of automatically blocking themes, scripts, feeds, plugins, tags, or other resources.
Blogger site owners
Review crawler controls carefully because Blogger can manage robots.txt through platform settings. Use the Blog/Blogger mode as a clean starting point, not as a replacement for settings you have not checked.
SEO professionals and developers
Add crawler-specific rules, custom paths, optional Anthropic crawl-delay values, and separate AI search/model-development preferences without cluttering the beginner interface.
What Robots.txt Can Do — and What It Cannot Do
✓ Good use: manage crawling
Use Allow and Disallow rules to tell compliant crawlers which URL paths they may request.
✓ Good use: crawler-specific preferences
You can target documented crawler product tokens such as Googlebot, GPTBot, ClaudeBot, or other supported tokens.
✕ Not a security system
Robots.txt is public. Do not put private or confidential URLs there and assume they are protected.
✕ Not a guaranteed noindex tool
For Google, a disallowed page can still be known from links. If Google must obey a noindex, it needs to be able to crawl the page and see that directive.
Robots.txt Syntax Explained in Plain English
A robots.txt file is made of crawler groups. Each group starts with one or more User-agent lines and is followed
by rules. The two core path rules are Allow and Disallow. A crawler chooses the group that matches
its product token; when more than one group matches the same token, standards-compliant crawlers combine those rules.
In this example, the wildcard * applies to crawlers that do not have a more specific matching group.
/private/ is disallowed, while the more specific allowed path can remain crawlable for crawlers that support the
standardized matching behavior. The Sitemap: record advertises the location of an XML sitemap; it is useful but
is not required for a valid robots.txt file and does not guarantee indexing.
What the main directives mean
- User-agent: identifies the crawler product token that a group applies to.
- Disallow: tells a matching compliant crawler not to request URLs that match the path.
- Allow: permits a more specific path within a broader blocked area when supported by the crawler.
- Sitemap: points crawlers that support the record to an absolute sitemap URL.
- Crawl-delay: is a non-standard extension. Google does not support it. Anthropic currently documents support for its bots, so only use it where the target crawler explicitly supports it.
Why the Templates Are Conservative
Many robots.txt generators automatically block long lists of directories. That can be risky because websites do not all use the same URL structure. This generator deliberately starts with fewer rules.
General Website
Starts with an open wildcard group. Add a custom Disallow only when you know the exact path you want compliant crawlers to avoid.
WordPress
The starter blocks /wp-admin/ while allowing /wp-admin/admin-ajax.php. It does not automatically block themes, plugins, CSS, JavaScript, feeds, tags, or other resources that may be needed for rendering or may be intentionally public.
Blog / Blogger
Starts open because Blogger, WordPress, Ghost, custom blogs, and other platforms use different URL patterns. Blogger also provides its own crawler settings, so review the platform's current controls before replacing an existing custom robots.txt configuration.
E-commerce
Starts open because checkout, filter, account, search, and faceted-navigation URLs vary widely between Shopify, WooCommerce, custom stores, and other platforms. Add platform-specific paths only after verifying them.
Mediapartners-Google and Robots.txt — What AdSense Publishers Should Know
Google AdSense uses a dedicated crawler called Mediapartners-Google to understand pages where Google ads are served. Google also documents Google-Display-Ads-Bot for AdSense site verification and advertising-related crawling.
Mediapartners-Google is a Google special-case crawler. Google says the global
User-agent: * group is ignored for this crawler, so you normally do not need a special allow rule simply because
your site uses AdSense. However, crawler-specific rules for Mediapartners-Google can directly affect AdSense crawling.
Explicitly allow ad crawlers
The Advanced Options toggle can add empty Disallow: groups for Mediapartners-Google and Google-Display-Ads-Bot, making your intent easy to review later.
Do not block them accidentally
If you specifically add User-agent: Mediapartners-Google followed by Disallow: /, Google warns that it may be unable to serve Google ads on affected pages.
The example above explicitly leaves crawling open for these ad-related crawlers. It is optional, but useful when you want an AdSense-aware robots.txt configuration that is easy to audit.
Training Crawlers and Search Crawlers Are Not the Same Thing
The simple “Block selected model-training controls” option adds full-site opt-out rules for GPTBot, ClaudeBot, and Google-Extended. These controls have different purposes and should not be confused with every AI-related crawler.
GPTBot
OpenAI documents GPTBot as a control for content you want excluded from potential model training. OpenAI separately uses OAI-SearchBot for ChatGPT search discovery.
ClaudeBot
Anthropic documents ClaudeBot for model-development crawling, while Claude-SearchBot and Claude-User have search and user-retrieval purposes.
Google-Extended
Google describes Google-Extended as a robots.txt product token that controls certain Gemini model-development and grounding uses. Google says it does not affect Google Search inclusion or ranking.
Robots.txt remains voluntary
These rules communicate your preference to services that honor robots.txt. They are not a firewall and cannot stop a crawler that ignores the file.
More Than a Basic Robots.txt Maker
A basic generator can turn one path into one Disallow line. This page is designed to help with the decisions around
that file as well: whether you need a custom robots.txt at all, which site-specific paths should be reviewed, how model-training
controls differ from AI search crawlers, and whether an existing file contains an obvious high-impact mistake.
- Simple mode: a three-step workflow for users who only need a sensible starting file.
- Advanced mode: custom crawler and path rules stay available without appearing on the main screen.
- Existing robots.txt quick check: paste an older file to flag common structural risks before editing it.
- AI crawler separation: training/model-development controls are not automatically treated as the same thing as search or user-retrieval crawlers.
- Browser-based workflow: generated and pasted robots.txt text is processed locally by the tool code in your browser.
- Human-readable guidance: the page explains what each choice does instead of assuming every visitor already knows technical SEO terminology.
Four Robots.txt Mistakes to Avoid
- Blocking the whole site by accident:
User-agent: *withDisallow: /is a high-impact rule. - Using Disallow as noindex: crawl blocking and search-result exclusion are different controls.
- Blocking resources needed for rendering: avoid blanket CSS or JavaScript blocks unless you have a tested reason.
- Copying a template without checking your URLs: a path that is correct for one CMS or store may be wrong for another.
Robots.txt Generator — Frequently Asked Questions
Do I need a robots.txt file for my website?
Not necessarily. A small public site does not need a custom robots.txt file simply to be indexable. Use one when you have a specific crawler-management need or want to communicate crawler preferences.
Does Disallow remove a page from Google?
No. Disallow controls crawling. Google can still know about a blocked URL from other links. If you want Google to obey a noindex directive, the page must remain crawlable so Google can read the noindex meta tag or HTTP header.
Where should I upload robots.txt?
Serve it as /robots.txt at the root of the exact host and protocol it applies to, such as https://example.com/robots.txt. Your CMS or hosting platform may provide a dedicated setting instead of direct file access.
Should I add Crawl-delay?
Only when you have a crawler-specific reason. Crawl-delay is a non-standard extension and Google does not support it. Some other crawlers publish their own support for it.
Can I block AI model-training crawlers but still allow AI search?
Yes, when a provider documents separate product tokens. This tool's simple AI option blocks GPTBot, ClaudeBot, and Google-Extended while leaving OAI-SearchBot, Claude-SearchBot, and Claude-User unchanged unless you explicitly block them in Advanced Options.
Is this tool private?
The robots.txt configuration is generated in your browser and is not uploaded to MZTechPro for processing. Normal webpage requests for assets, analytics, consent tools, or advertising may still occur.
Does this tool validate an existing robots.txt file?
The Advanced Options section includes an Existing robots.txt Quick Check that flags several common structural and high-impact issues, including wildcard site-wide blocks, unsupported noindex lines, invalid sitemap URLs and oversized files. It is intentionally described as a quick check rather than a complete crawler emulator. Always test the published file on the live site.
Does every small website need a custom robots.txt file?
No. Many small public websites work perfectly well without a custom robots.txt configuration, and some hosted platforms manage the file for you. Create or edit one when you have a clear crawl-control requirement rather than adding restrictions simply because a robots.txt file exists.
Should I add Mediapartners-Google to robots.txt for AdSense?
You do not normally need a special allow rule simply because you use AdSense. Google documents Mediapartners-Google as a special-case crawler that ignores the global User-agent: * group. However, if you create a crawler-specific Mediapartners-Google group, do not accidentally block it with Disallow: / when you want AdSense crawling. This tool can optionally add explicit allow-all groups for Mediapartners-Google and Google-Display-Ads-Bot.
