A robot.txt file is a text file that enables communication between web crawlers and robots on a website. It gives web crawlers instructions about which part of the website should be crawled and which one should be ignored. 

Robot.txt file serves some main purposes like:-

Access control: The owners of the website use it to prevent web crawlers from accessing certain directories available on their sites.


Crawl Optimization: By directing the areas of the website to be crawled, website owners might help crawlers prioritize and focus on the important content. This ensures the crawling of the valuable pages that are indexed.

Resource Control: Big websites use robot.txt to avoid server overload when too many crawlers are seeking requests.  They do this by blocking some resource-intensive areas. 

This file is established in the root directory of the website. Its syntax contains one or more user-agent lines which helps identify the rules for the crawlers. This is then followed by "Allow" or "Disallow" directions that specify the path a crawler can or cannot access.

Though the web crawlers are good at following instructions it is important to know that following these commands is voluntary. Malicious Robots do tend to ignore these instructions.

Benefits Of Robots.txt File

This feature is very helpful when you don’t want to showcase a few sections of your website in the search results like staging environments or pages that contain sensitive information. 

Avoid Crawling Wasted Resources: The search engine might waste crawler time without a robot.txt file. It may also waste resources crawling or indexing pages that are not meant to be shown to the public. This ultimately results in insufficient crawling and indexing, Ultimately slowing down the process of getting your important pages scrolled. 

Prevent Duplicate Content Issues: In case you have multiple versions of the same content you can utilize the robots.txt file and instruct it to not crawl and index the duplicate versions, which leads to ignorance of potential duplicate content issues.


Support Website Maintenance: While website maintenance and major updating you can instruct the robots.txt file to block search engine crawlers from accessing the site temporarily. This prevents crawlers from indexing incomplete or inconsistent content, which negatively impacts your search engine rankings. 

While the robot.txt file is not a strict rule to follow but is beneficial in many ways. It helps in maintaining control over your website’s crawling and indexing method. It also ensures that search engines have their focus on the important and relevant pages of the website. 

However, it is very important to know that the robots.txt file is not the trustworthy way to prevent access to your website’s content.

Therefore, it should be used in conjunction with other security measures, such as password protection or IP restrictions, for sensitive areas of your website.
