Use this free robots.txt builder to create and download a valid robots.txt file in seconds. Whether you need a simple robots.txt maker for a new WordPress site or a custom crawler configuration for a large Laravel application, this tool generates the exact syntax search engines expect — no coding required.
⚠️ Important: Blocking a page in robots.txt does not remove it from Google search results. If you need to fully deindex a page, use a noindex meta tag instead — and make sure the page is still crawlable so Google can read the tag

What Is a robots.txt File?
The robots.txt file is a plain text file placed at the root of your website (e.g., https://example.com/robots.txt) that instructs search engine crawlers which pages or sections of your site they are allowed or not allowed to access. It is part of the Robots Exclusion Protocol — a standard followed by all major search engines including Google, Bing, and Yandex.
Every time a search engine bot visits your website, it first checks robots.txt before crawling any page. If a rule blocks it from a certain path, the bot skips that path entirely. This gives you direct control over how your site is crawled and which content gets discovered.
Key robots.txt directives:
*
User-agent — specifies which bot the rule applies to. Use * for all bots, or name a specific one like Googlebot or Bingbot.
*
Disallow — tells the bot not to crawl the specified path. For example, Disallow: /admin/ blocks all crawlers from your admin panel.
*
Allow — explicitly permits crawling of a path, even if a parent directory is disallowed. Useful for overriding a broad Disallow rule.
*
Crawl-delay — sets a delay (in seconds) between requests from the bot. Helps reduce server load for high-traffic sites.
*
Sitemap — points crawlers to your XML sitemap URL so they can discover all your pages efficiently.
robots.txt vs noindex — what's the difference?
This is one of the most commonly misunderstood distinctions in SEO. robots.txt controls crawling — it stops bots from visiting a page. A noindex meta tag controls indexing — it lets bots visit the page but tells them not to include it in search results. If you block a page in robots.txt, Google cannot read its noindex tag and may still index the URL if other sites link to it. For complete removal from search results, use both: block crawling with robots.txt AND add a noindex tag.

Frequently Asked Questions
Upload it to your website's root directory so it is accessible at https://yourdomain.com/robots.txt. In WordPress, place it in the root folder (same level as wp-config.php). In Laravel, place it inside the /public folder. In cPanel or FTP, upload it to public_html/. The file must be named exactly robots.txt in lowercase.
Yes, significantly. A poorly configured robots.txt can accidentally block Google from crawling important pages, killing your rankings. A well-configured file helps Google focus its crawl budget on your most important pages, improving how quickly new content gets indexed. Common mistakes include blocking CSS and JS files (which Google needs to render pages), blocking paginated URLs, or forgetting to add the sitemap reference.
No — and this is a critical distinction. robots.txt prevents crawling, not indexing. If other websites link to a page you have blocked in robots.txt, Google can still discover that URL and index it (without reading its content). To fully remove a page from Google search results, you need to either: (1) use a noindex meta tag on the page (and allow crawling so Google can read it), or (2) request removal via Google Search Console.
Yes. You can write multiple User-agent blocks in a single robots.txt file, each with its own set of rules. For example, you can allow Googlebot full access while blocking all other bots, or give Bingbot a crawl delay while letting Googlebot crawl freely. Each User-agent block applies only to the bot(s) named in it.
Add separate User-agent blocks for each AI crawler you want to block. The most common AI scrapers and their user-agent names are: GPTBot (OpenAI), Claude-Web (Anthropic), CCBot (Common Crawl, used by many AI datasets), Google-Extended (Google's AI training crawler), Amazonbot (Amazon), and meta-externalagent (Meta/Facebook AI). Use our "Block AI Scrapers" preset above to generate this automatically. Note that not all AI companies respect robots.txt — it is a voluntary standard, not a technical barrier.
Crawl-delay tells a bot how many seconds to wait between requests to your server. For example, Crawl-delay: 2 means the bot waits 2 seconds between page visits. This is useful if your server has limited resources and bot traffic is causing slowdowns. Important: Google officially ignores the Crawl-delay directive. To control Googlebot's crawl rate, use Google Search Console instead. Crawl-delay is respected by Bingbot, Yandex, and several other crawlers.
Disallow: / blocks the bot from crawling your entire website — every single page and directory. Disallow: (with nothing after the colon) means the bot is allowed to crawl everything — it is effectively the same as having no Disallow rule. An empty Disallow is often used alongside a specific User-agent block to explicitly grant full access to a particular bot while restricting others.
Yes. Crawl budget is the number of pages Googlebot will crawl on your site within a given timeframe. For large sites (thousands of pages), wasting crawl budget on low-value pages like /tag/, /search/?q=, pagination parameters, or /cart/ means important pages get crawled less frequently. Using robots.txt to block these low-value URLs helps Google focus its crawl budget on your core content pages, which can speed up indexing of new or updated content.
No. robots.txt is a public file — anyone can read it by visiting yourdomain.com/robots.txt. It is a courtesy instruction for well-behaved bots, not a security tool. Malicious bots and scrapers routinely ignore it. Never rely on robots.txt to protect sensitive content. Use proper authentication (login walls, .htaccess password protection, or server-level access controls) to secure private data.
No. Each subdomain needs its own robots.txt file. A robots.txt at example.com/robots.txt does not apply to blog.example.com or shop.example.com. You need to create and upload a separate robots.txt at the root of each subdomain if you want to control crawling there.
