I have a url on my site that is for a reg file (microsoft registry file), which is similar to a text file, that is breaking the validation every once in a while. This wont show ads as it is not able to. How can i make it so this does not break my validation? I am assuming you are ignoring .txt files with your validation tests. Can you add .reg files as well?
Any file/page in the Google index is fair game. You need to use your robots.txt file to prevent Google from indexing that page, and your problem will be solved
