← Back to blogsLearn what Robots.txt is, how it works, and how to configure it correctly to improve website crawling and support your Technical SEO strategy.
Every website contains pages that should be visible to search engines and others that should remain private or unnecessary for indexing. This is where the Robots.txt file becomes important.
A Robots.txt file tells search engine crawlers which parts of your website they are allowed to crawl and which parts they should avoid. It acts as a set of instructions for search engine bots before they begin crawling your website.
Although Robots.txt is a simple text file, using it incorrectly can prevent important pages from appearing in Google Search. Understanding how it works is an essential part of Technical SEO.
In this guide, you'll learn what Robots.txt is, how it works, how to create it, common mistakes to avoid, and best practices for optimizing your website.
Robots.txt is a plain text file placed in the root directory of your website.
It provides instructions to search engine crawlers such as Googlebot, Bingbot, and other web crawlers about which pages or folders they should or should not crawl.
For example:
Robots.txt does not directly improve rankings, but it helps search engines crawl your website more efficiently.
Robots.txt helps website owners:
It is especially useful for large websites with thousands of pages.
When a search engine crawler visits your website, one of the first files it requests is:
https://yourwebsite.com/robots.txt
The crawler reads the instructions inside the file before visiting other pages.
If a page is blocked, the crawler generally avoids crawling it.
If a page is allowed, the crawler proceeds to visit it.
The Robots.txt file should always be placed in the root directory of your website.
Example:
https://yourwebsite.com/robots.txt
Examples:
https://example.com/robots.txt
https://hirloyeacademy.com/robots.txt
There should only be one Robots.txt file for each domain.
A simple Robots.txt file looks like this:
User-agent: *
Disallow:
Sitemap: https://yourwebsite.com/sitemap.xml
This means:
The User-agent directive specifies which crawler the rule applies to.
Example:
User-agent: Googlebot
Applies only to Google's crawler.
To target all search engines:
User-agent: *
The asterisk (*) means "all crawlers."
The Disallow directive tells crawlers not to access a page or directory.
Example:
User-agent: *
Disallow: /admin/
This tells search engines not to crawl the admin folder.
The Allow directive permits crawling of a specific page or folder.
Example:
User-agent: *
Allow: /blog/
This explicitly allows search engines to crawl the blog section.
You can specify your XML Sitemap within Robots.txt.
Example:
Sitemap: https://yourwebsite.com/sitemap.xml
This helps search engines locate your important pages.
User-agent: *
Disallow:
All pages can be crawled.
User-agent: *
Disallow: /admin/
Useful for preventing crawlers from visiting administrative areas.
User-agent: *
Disallow: /login/
Login pages usually do not need to be crawled.
User-agent: *
Disallow: /search/
Internal search result pages are generally not useful in Google Search.
User-agent: *
Disallow:
Sitemap: https://yourwebsite.com/sitemap.xml
This is a common configuration for many websites.
Typical pages to block include:
Blocking these pages helps search engines focus on valuable content.
Avoid blocking:
Blocking important resources may prevent search engines from properly understanding your website.
Many beginners confuse these concepts.
Controls crawling.
Example:
"Do not visit this page."
Controls indexing.
Example:
"You may crawl this page, but don't include it in search results."
A page blocked in Robots.txt may still appear in search results if other websites link to it. If your goal is to keep a page out of search results, use the appropriate indexing controls rather than relying solely on Robots.txt.
Robots.txt | XML Sitemap |
Controls crawling | Helps discover pages |
Blocks unnecessary areas | Lists important URLs |
Guides search engine bots | Guides search engines to valuable content |
Located at /robots.txt | Usually located at /sitemap.xml |
Both files work together as part of Technical SEO.
Follow these recommendations:
A well-maintained Robots.txt file improves crawl efficiency without restricting important content.
Avoid these common errors:
Example:
User-agent: *
Disallow: /
This prevents search engines from crawling your entire website.
Search engines need these files to understand how your pages are rendered.
Never block pages you want users to find through Google Search.
If your website structure changes, review and update your Robots.txt file.
Including your XML Sitemap helps search engines discover important pages more efficiently.
After updating your Robots.txt file:
Regular testing helps ensure your instructions are working as intended.
✔ Place the file in the root directory
✔ Use the correct User-agent
✔ Block only unnecessary folders
✔ Allow important content
✔ Include your XML Sitemap
✔ Keep the file updated
✔ Test after changes
✔ Review crawl reports
✔ Avoid blocking CSS and JavaScript
✔ Verify important pages remain crawlable
Helpful tools include:
These tools help monitor crawl behavior and identify configuration issues.
Robots.txt is a text file that provides instructions to search engine crawlers about which parts of a website they should or should not crawl.
It does not directly improve rankings, but it supports Technical SEO by helping search engines crawl your website more efficiently.
Most websites benefit from having one, especially if they want to guide crawlers or reference an XML Sitemap.
No. Robots.txt is publicly accessible and should not be used to protect sensitive information. Secure private content with authentication and proper access controls.
It is placed in the root directory of your website and is typically available at:
https://yourwebsite.com/robots.txt
Robots.txt is a small but essential part of Technical SEO. It helps search engines understand which areas of your website they should crawl while allowing them to focus on your most valuable content.
A properly configured Robots.txt file improves crawl efficiency, supports your XML Sitemap, and helps prevent unnecessary pages from being crawled. However, it's important to use it carefully—blocking the wrong pages or resources can negatively affect your website's visibility.
Regularly review your Robots.txt file, especially after major website updates, and monitor your crawl reports in Google Search Console to ensure your SEO strategy stays on track.
