Free Robots.txt Generator for SEO | Create & Test Rules

Take absolute control of your website's crawl budget and indexation. Instantly generate a flawlessly formatted robots.txt file to guide search engines, block rogue AI scrapers, and point Google directly to your XML sitemap.

Your robots.txt file is the front door to your website's server. Before Google, Bing, or OpenAI scans a single page on your site, they check this file to see what they are allowed—and forbidden—to look at. A single typo in this file can accidentally de-index your entire website from Google overnight. Our Free Robots.txt Generator eliminates syntax errors entirely. Using an intuitive, visual dashboard, you can define global access rules, set server crawl delays, and add highly specific allow/disallow paths for individual web spiders without writing a single line of code.

How to Generate Your robots.txt File

Our generator uses an intelligent, state-driven engine to format your directives perfectly. Follow these steps to secure your server:

1. Set the Global Policy: By default, you want to Allow All. Only change this to "Disallow All" if you are working on a private staging server or a website currently under construction that you do not want anyone to find.
2. Attach Your Sitemap: Paste the absolute URL of your XML sitemap (e.g., https://yoursite.com/sitemap.xml). This provides search engines with a perfect map of the pages you want them to crawl.
3. Define Specific Directives: Click "Add Custom Rule" to block specific bots from accessing private folders. For example, if you run a WordPress site, you should block Googlebot from accessing the /wp-admin/ directory.
4. Export and Upload: Click "Copy Code". Open a plain text editor (like Notepad), paste the code, and save the file as exactly robots.txt. Upload this file to the root directory of your web hosting server.

What Exactly is the Robots Exclusion Protocol?

Before a web crawler (a "bot" or "spider") scans your website to index it into a search engine, it always checks for a specific file at the root of your domain: yoursite.com/robots.txt.

This file is written in a standardized syntax known as the Robots Exclusion Protocol (REP). It is a polite set of instructions telling the bot what it is allowed to look at. A properly formatted file consists of two primary elements:

• User-agent: Identifies which specific bot the rule applies to. An asterisk (*) is a wildcard that applies to every bot on the internet.
• Disallow: Tells the bot which specific URL paths it is forbidden to crawl.

Important Note: A robots.txt file is a guideline, not a firewall. Respectable bots from Google, Microsoft, and OpenAI will strictly obey your rules. However, malicious scraper bots and hackers will completely ignore the file. Do not use robots.txt to hide sensitive passwords or secure user data; use server-level password protection (.htpasswd) instead.

Crucial SEO Error: robots.txt vs. NoIndex Tags

The most common and devastating mistake junior SEOs make is attempting to remove a page from Google Search by putting it in their robots.txt file.

If you put Disallow: /secret-page/ in your robots file, you are telling Google not to crawl the page. However, if another website links to your secret page, Google will still put the URL in their search results! It will simply appear with a generic description reading: "No information is available for this page."

To completely remove a page from Google Search, you must use a noindex meta tag inside the HTML of the page itself.

Here is the paradox: If you block a page in robots.txt, Google's bot is forbidden from visiting the page. If it cannot visit the page, it cannot see the noindex tag, meaning the page will remain stuck in the search results! Never block a page in robots.txt if you want it de-indexed. Allow Google to crawl it, read the noindex tag, and drop it from the search engine naturally.

Modern SEO: Blocking ChatGPT and AI Scrapers

In the modern era of Generative AI, companies like OpenAI, Anthropic, and Google train their massive Large Language Models (LLMs) by scraping billions of words from public websites.

Many publishers and news organizations are choosing to opt out of this mass data collection. You can use our custom rule builder to specifically block AI bots from stealing your content to train their algorithms.

To block OpenAI's web crawlers, add a custom rule in our tool, select the bot GPTBot (which crawls for training data) or ChatGPT-User (which crawls to answer live user prompts), and set the path to / to block them entirely from your site.

Frequently Asked Questions (FAQ)

What happens if I don't have a robots.txt file?

If a search engine crawler requests /robots.txt and receives a 404 Not Found error, it simply assumes there are zero restrictions. It will proceed to crawl and index every single publicly accessible page on your entire website.

How does the 'Crawl-delay' directive work?

A crawl delay tells a bot to wait a specific number of seconds between page requests. If your server is cheap or slow, aggressive bots can crash your site by requesting 100 pages a second. A crawl delay prevents this. Note: Googlebot ignores this directive (you must set Google's crawl rate in Google Search Console), but Bing, Yandex, and Baidu respect it.

Can I block specific file types like PDFs or Images?

Yes. The syntax allows for wildcards. To block all PDF files, you would add a custom rule with the path: /*.pdf$. To block Google from putting your images in Google Images, you would use the Googlebot-Image user-agent and disallow the specific image directories.
