@virgilbrewster I think the best way is to simply upload the PDF file into WordPress uploads folder, following this path:

wp-content/uploads

However, you can actually uploaded anywhere on your server, but… Why the uploads files? 

Simply because we all forget things, especially when we emigrate sites to other hosting or do upgrades on our blogs, the uploads folder is a safe place in my opinion.

You can then create a nice folder inside the uploads folder like this:

wp-content/uploads/mybook/YOUR-BOOK.PDF

Or

wp-content/uploads/download/YOUR-BOOK.PDF

** The other way is to create a folder on the root directory, to avoid long URL, this can easily done by FTP or via your host cPanel, for example:

Your-Blog.com/downloads/Your-Book.PDF

I hope this helps, and good luck.

Aweber allows you to attach a PDF file to an auto responder so you don’t need to place it on your site at all.
