Hello,
What is the importance of robot.txt in SEO?

[thaichacha]

It's important to update your Robots.txt file if you add pages, files or directories to your site that you don't wish to be indexed by the search engines or accessed by web users. This will ensure the security of your website and the best possible results with your search engine optimization.

The robots.txt file, also known as the robots exclusion protocol or standard, is a text file that tells web robots (most often search engines) which pages on your site to crawl. It also tells web robots which pages not to crawl. Let's say a search engine is about to visit a site.

Robot.txt file is not for public use, and this file contains information for search engine crawler, information tells crawler whether to read the website and what page crawler should read on the site.
