Does anyone know if there are any official or intelligently assumed multipliers that you can put on a file download, to estimate how many people actually get a hold of a file off of one person downloading it? For example, if my website offers some articles and white papers to download, and a person from XYZ company downloads the white paper, based on a certain reach metric multiplier, can I assume that since he downloaded it, that means at least X more people in his company now have a copy of this file? I am trying to see if I can gauge a "reach" metric for file downloads, as I've heard many times that people will come in, download a file, and simply share it with all of his peers so that they don't have to come in and download it themselves. Are there any legitimate sources that have officially defined this type of metric? Thanks for any help!
