Robots.txt is a text (not html) file you put on your site to tell search robots which pages you would like them not to visit. Robots.txt is by no means mandatory for search engines but generally search engines obey what they are asked not to do. It is important to clarify that robots.txt is not a way from preventing search engines from crawling your site (i.e. it is not a firewall, or a kind of password protection) and the fact that you put a robots.txt file is something like putting a note “Please, do not enter” on an unlocked door – e.g. you cannot prevent thieves from coming in but the good guys will not open to door and enter. That is why we say that if you have really sen sitive data, it is too naïve to rely on robots.txt to protect it from being indexed and displayed in search results.

Robot.txt is used to crawl the pages website. It tells that which part of the area should not be accessed. We can define the pages which should not be accessed by putting the disallow tag in robot.txt. Those disallow pages are restricted to visit. It also help to index the web content.

You can ask your web hosting provider to upload it under your control panel (root directory of the website) and webmaster will pick it automatically.

If you have access then you can upload it from your end.
