The post is intended for Magento 2 store owners or those responsible for the store's SEO. You are already aware of the significance of the robots.txt file, which is a text file that informs web robots, such as search engines, which pages should be crawled and which should not.
Google explains that a robots.txt file informs search engine crawlers which pages or files they can or cannot request from your site.
Every website, including Magento 2 stores, must have this tiny file. Fortunately, Magento 2's default settings allow for the creation of a robots.txt file, which will be demonstrated in this article.
Meta robots provide webmasters with a way to give search engines information about their stores. This code, located in the head section of your webpage, instructs the search engines on what to follow and what to ignore, as well as which links to follow and which links to avoid.
