robots.txt and upload it to the root directory of your website (e.g., yourdomain.com/robots.txt).The Robots.txt Generator by GrowthSyntax is a free, browser-based SEO tool that helps website owners, developers, and digital marketers create perfectly formatted robots.txt files in seconds. Control which search engine bots can crawl your site, block restricted directories, set crawl delay, add your XML sitemap URL, and manage individual bot permissions for Google, Bing, Yandex, and Applebot — all with a live preview and instant download.
A robots.txt file is a plain text file placed in the root directory of your website that tells search engine crawlers which pages or directories they are allowed or not allowed to visit. It is one of the first files Googlebot, Bingbot, and other crawlers check when they visit your website. A correctly configured robots.txt file helps protect sensitive pages from being indexed, reduces unnecessary crawl budget usage, and gives you precise control over how search engines interact with your site.
An incorrectly configured robots.txt file can accidentally block search engines from crawling your most important pages — preventing them from appearing in Google search results entirely. On the other hand, a well-optimized robots.txt file helps you protect admin areas, staging pages, duplicate content, and private directories from being indexed. The Robots.txt Generator takes the guesswork out of this process by generating a correctly formatted file with real-time preview and one-click download.
Set default access rules for all crawlers at once — allow all bots to crawl your site or block them entirely with a single dropdown selection.
Block specific directories like /wp-admin/, /private/, or /cgi-bin/ from being crawled by entering them one per line in the restricted directories field.
Set individual rules for Googlebot, Bingbot, YandexBot, and Applebot — allowing or blocking each one independently from your global settings.
Specify a crawl delay in seconds to prevent bots from overloading your server — particularly useful for high-traffic or resource-constrained websites.
Add your sitemap URL directly to your robots.txt file so search engines can discover and index all your important pages more efficiently.
See your robots.txt output update in real time as you adjust settings, then copy it to clipboard or download it as a ready-to-upload .txt file.
Stop writing robots.txt manually and risking costly crawler mistakes. Use the Robots.txt Generator by GrowthSyntax to create a perfectly formatted file with advanced bot control, crawl delay, and sitemap integration — completely free, instantly downloadable, and always accurate.
