I have WordPress site and an iframe, which src is 'http://my-website.com/www.downloadedwebsite.com/index.html'. I had to download iframed website, because I'm modifying a few things in it and that requires same-origin. There are no backlinks to this URL - just single iframe src'ing to it, however, I see Google has indexed it (bad!).
How can I stop Google from indexing or following anything that is inside "http://my-website.com/www.downloadedwebsite.com/" directory?
