I would like to know the best way to protect Clickbank ebook downloads without using DLGuard etc. and finding it on Google or Alexa. Someone posted these instructions. Add a folder named download with a blank index file and then make a funny name for the download page inside the download folder. This will prevent the page / file from being indexed or found. You could also add things like if referrer=clickbank/paypal etc display download page else 404 error.
