  1. What is Robots.txt? 

Robots.txt is a text file that website owners create and place in the root directory of their website. It tells search engine bots which pages or files on their website should be crawled and which ones should be excluded. The file is a set of instructions that search engine bots follow when crawling a website. 

  1. The Purpose of Robots.txt in Technical SEO. 

The primary purpose of robots.txt in technical SEO is to control which pages or files on a website are crawled by search engine bots. Website owners use robots.txt to allow or disallow access to specific parts of their websites. This can be useful in several scenarios, such as: 

  1. a) To exclude duplicate content: In some cases, a website may have duplicate content on different pages. This can hurt the website’s SEO because search engines will not know which page to rank higher in search results. By using robots.txt to exclude duplicate content, website owners can ensure that search engines only crawl and index the pages they want.
  2. b) To protect sensitive information: Some parts of a website may contain sensitive information that the website owner does not want to be accessible to the public. By using robots.txt, website owners can exclude these pages from search engine crawlers.
  3. c) To prevent crawling of non-public pages: Some websites may have pages that are only accessible to logged-in users or contain sensitive information that the website owner does not want to be publicly accessible. By using robots.txt, website owners can prevent these pages from being crawled and indexed by search engines.

  1. How to Create a Robots.txt File?

Creating a robots.txt file is a simple process. Website owners can use a text editor to create the file or use an online robots.txt generator tool. Once the file is created, it should be uploaded to the root directory of the website. 

  1. Best Practices for Using Robots.txt.

To ensure that robots.txt is used effectively in technical SEO, there are several best practices that website owners should follow: 

  1. a) Use the Disallow directive: The Disallow directive tells search engine bots which parts of a website should not be crawled. This is the primary function of the robots.txt file.
  2. b) Use the Allow directive: The Allow directive tells search engine bots which parts of a website should be crawled. This can be useful when website owners want to exclude specific pages but still want search engines to crawl certain pages.
  3. c) Use a wildcard when necessary: Website owners can use the “wildcard to specify which parts of their website should be excluded or allowed. For example, using “Disallow: /wp-admin/” would exclude all pages that contain “/wp-admin/” in the URL.
  4. d) Test the robots.txt file: Website owners should test the robots.txt file to ensure that it is working correctly. Google Search Console has a robots.txt tester that can be used to check for errors or issues.

In conclusion, robots.txt is an essential component of technical SEO. It allows website owners to control which parts of their websites are crawled by search engine bots. Website owners should use best practices when creating and implementing their robots.txt file to ensure that it is effective in improving their website’s visibility in search engine results.
