These are the REAL free guides. No cost for you, no cost for me.
Almost a year ago, I mentioned this:
Roughly 10% of unique visitors download an English-language PDF (although this can shoot up to 18% during March, a heavy vacation-planning month).
Consumers prefer PDFs to printed-and-mailed materials – Currently 350-400% more consumers will download a PDF from the site than fill out a form requesting a printed copy be mailed to them.
Of course, that only works if you don’t hide the stuff on a form page.
