If I were to upload pdf files, is there a way to let google crawl the pdfs? Was thinking I could upload a bunch of pdfs and get long-tail keyword traffic if people search for specific phrases which are in the pdfs.
Whoever uploads sensitive information to the internet without protecting it...well I can't help them.
Your RSS feed doesn't include password protected files. This could be done similarly - only crawl unprotect PDF files.
If you make a plugin, I'll gladly buy it!
