When you enter this in google, Filetype : pdf for say "quit smoking" it pulls the pdf files across the internet which are downloadable, and are in google search format. along sidfe their urls. How can you prevent your pdf from being indexed? so that nobody can find it in a google search, so the seo spiders cannot get to it. so when this gets entered Filetype : pdf "entry" my PDFs which are hosted Dont get listed? {what is the solution, using no follow for example, in the folder ?} but the downloaders from my Optin form should be able to download the ebook with No restrictions.
What are the steps for that ? and what would I name the file? and code what would I include in the file ?
