You might have heard many points about both robots Html tags plus the text files uploaded to the root servers of the sites that are also called as the robots files. Now let's see what the differences between the two terms are actually for avoiding confusion. As we have already discussed, the robots tags are the ones being added to the headings sections of the sites and they may or may not be used but the robots files are simple text files that are created by using the simple text processing documents such as notepads of the Windows operating softwares and then some codes and commands are being written inside them which are relevant to deciding over certain parts and folders of the sites get visited by the search engines or not. For example, as it is widely practiced by the webmasters, the images folders at websites are added to the list of the folders which are not going to be crawled by the search engines robots and so the files will not be visited too and no information about them will be shared if you search for them in the image search engines and portals.

Please note that the robots text file is made up of a simple text document, just like the rest of simple letters you are writing via notepad program on your computer and is generally very small in size due to the limited number of words and symbols being used and written on that. Your site's robots text file may even be smaller than one kilobyte in size and it needs to be uploaded to the root directory of your hosting account to remain functional. You know, it's highly recommended and indeed necessary to upload the robots text file to the root section of the sites and not putting them inside some directories or folder online. This is because the search engines robots will search for the robots files as soon as they arrive at a site's main server address and they begin reading through the points inside the robots text files immediately. There is no need to write lengthy descriptive points and paragraphs inside the robots text files because they will not be read by the crawlers robots and instead, simply specifying the folders you want get crawled and the ones you do not is enough.

The robots tags on the other hand are not recognized to be coming in the form of new text files because they simply are being recognized and known to be inseparable parts of the websites and internet pages. They go along with the other tags into the headings sections of the sites and this is done to ensure they too are easily seen and interpreted by the search engines. Usually, the robots text files are more important than the tags because as mentioned earlier and in previous topics, search engines have their own methods and ways of crawling sites and interpreting the files and resources they encounter but the robots text files have been known to remain very active and significant when search engines reach them and begin reading them. You may have a question regarding the way domains and subdomains are actually performing online. For instance, as you already know, the modern hosting accounts today allow webmasters running several sites together and at the same time using only a single shared account and you can easily add a robots text file to the every domain name which is accessible from your hosting account and in fact subdomains too can have them.
