🤖 Free Robots.txt Generator

Create a pristine Robots.txt file to optimize your SEO crawl budget. Safely instruct Googlebot what it should—and shouldn't—index.

Why Your Website Needs a Robots.txt File

Before Google indexes your website, its crawlers ("bots") first look for a file at `/robots.txt`. If you don't have this file configured correctly, you are leaving your technical SEO to chance.

  • Maximize Crawl Budget: Google spends a limited amount of time on your site. By using `Disallow` rules on admin folders (`/wp-admin/`) or internal searches, you force the bot to index your valuable money-pages.
  • Prevent Duplicate Content Penalties: If you use query parameters for tracking or filtering (e.g., `?sort=price`), robots.txt prevents search engines from indexing these variations as duplicate content.
  • Sitemap Discovery: Your `robots.txt` is the absolute best place to declare the location of your `sitemap.xml` file, ensuring search engines find all your links instantly.
  • Block Unwanted AI Scrapers: In 2026, you can explicitly use rules in your robots.txt to prevent generative AI companies from using your site's data to train their models without compensation.

Frequently Asked Questions

What is a robots.txt file?

It is a plain text file placed in your website's root directory that communicates with web crawlers (like Googlebot), telling them which parts of your site they should or shouldn't scan.

Where should I place the robots.txt file?

It must be placed in the highest-level root directory. For example, it must be accessible at exactly `https://www.yourdomain.com/robots.txt` to function correctly.

Can a robots.txt file hide my site from hackers?

No. Robots.txt is a public directive, not a security protocol. Malicious scrapers will ignore the rules entirely. Never put sensitive data paths in your robots.txt file—use authentication instead.

How robots.txt works

robots.txt is a plain-text file at the root of your domain (https://example.com/robots.txt) that tells well-behaved crawlers which paths they may fetch. Each block starts with a User-agent line naming a crawler (or * for all), followed by Disallow and Allow rules matched against the URL path. A Sitemap: line pointing at your XML sitemap helps search engines discover pages faster.

  • It controls crawling, not indexing. A URL blocked in robots.txt can still appear in search results if other sites link to it. To keep a page out of the index, let it be crawled and add a noindex meta tag instead.
  • Don't block CSS and JavaScript. Google renders pages; blocking asset folders makes your pages look broken to it and can hurt rankings.
  • The longest matching rule wins. Allow: /blog/ beats Disallow: / for anything under /blog/. Use $ to anchor a pattern to the end of a URL and * as a wildcard.
  • It is public and advisory. Anyone can read it, and malicious bots ignore it. Never use it to "hide" admin panels — protect those with authentication.

Common configurations

Allow everything, declare the sitemap — the right default for most content sites: a single User-agent: * block with no Disallow rules and a Sitemap: line.

Keep crawlers out of internal search and cart pages — e-commerce sites often disallow /search, /cart and URLs with sorting parameters so crawl budget goes to product pages.

Opt out of AI training crawlers — separate User-agent blocks for GPTBot, CCBot, Google-Extended and similar let you decline AI training while still allowing normal search indexing. The generator includes these as a toggle.

After uploading the file, confirm it with Google Search Console's robots.txt report. A syntax error there usually means a stray blank line between a User-agent and its rules, or a rule written with a full URL instead of a path.
