Keep the PDF file(s) in a separate directory and exclude the search bots
by using a robots.txt file:
User-agent: *
Disallow: /pdf_directory/
This will keep out Google, Yahoo, etc and all other legitimate search
engines (those that honor the robots.txt file). I've used this technique
for years to prevent them from snarfing up my large images.
But note that honoring the robots.txt file is strictly voluntary: Legit
companies like Google honor it, spammers and scammers run their own
spiders that don't...
