The Newbies Guide to Robots.txt: How Important Robots.txt File

Are you new to the world of web development and SEO? Have you heard of the robots.txt file but need clarification on its importance? Well, you are in the right place! In this article, we will explain what robots.txt is and why it is important for your website’s search engine optimization (SEO).

First things first, let’s define what robots.txt is. It is a file that tells search engine robots which pages or sections of your website to crawl and index and which to avoid. In other words, it gives instructions to search engines on which pages should be visible in search results and which should not. The file is usually placed in the root directory of your website and can be accessed by adding “/robots.txt” to the end of your website’s URL.

Now, why is this file so important? Well, here are some reasons:

1. Improve Website’s Crawl Ability:

  • Using a robots.txt file, you can direct search engine robots to crawl and index only the pages you want.
  • It can help prevent search engines from wasting resources on pages that are not important or relevant and can also help prevent duplicate content issues.

2. Block Sensitive Content:                            

  • If certain pages or sections of your website contain sensitive information or should not be publicly available, you can use robots.txt to block search engine robots from accessing them.
  • It also can help protect your website from unauthorized access and potential security breaches.

3. Avoid Penalties:

  • If your website has duplicate content or spammy pages, search engines may penalize it by lowering its ranking or removing it from search results altogether.
  • Using a robots.txt file can prevent search engines from crawling and indexing these pages, which can help avoid penalties.

Now that you understand the importance of robots.txt file let’s discuss some best practices for creating and using it:

1. Please keep it simple:

  • txt file should be simple and easy to understand. Avoid using complex directives or syntax that might confuse search engine robots.

2. Test it:

  • Before you upload the robots.txt file to your website, test it to ensure it works correctly.
  • You can use online tools like Google Search Console to check if search engine robots can access your website’s pages.

3.Update it regularly:

    • As your website evolves, you may need to update your robots.txt file to reflect these changes.
    • Regularly review and update your file to ensure search engine robots can crawl and index the right pages.

4. Use specific directives:

  • The most common directives in robots.txt are “Disallow” and “Allow.” “Disallow,” tells search engine robots not to crawl or index a specific page or section of your website, while “Allow” allows them to crawl and index a specific page or section.
  • You can also use wildcards to block or allow multiple pages or sections at once.

5. Be careful with blocking pages:

  • While robots.txt can be a useful tool to block pages or sections of a website, you should use it cautiously.
  • Blocking too many pages could harm your website’s SEO by preventing search engine robots from crawling and indexing important pages.

6. Use other methods for sensitive content:

  • If you have sensitive content on your website that you do not want publicly available, robots.txt may not be enough to protect it.
  • Use other methods, such as password protection or a secure login page, to prevent unauthorized access.

7. Consider using meta robots tags:

  • In addition to robots.txt, you can also use meta robots tags to give search engine robots more specific instructions about crawling and indexing your website’s pages.
  • These tags can be added to individual pages and provide more granular control over how search engine robots interact with your website.

8. Regularly monitor your website’s crawl errors:

  • Even with a properly configured robots.txt file, search engine robots may still encounter errors when crawling your website.
  • Regularly monitoring your website’s crawl errors can help you identify and fix any issues impacting your website’s SEO.


In the summary robots.txt is an important tool for improving your website’s SEO and protecting it from potential security risks. In this article and regularly monitoring your website’s crawl errors, you can create a robots.txt file that is effective and easy to manage.
