Jon Morrow is the gold standard in this arena, and this post encapsulates that. He consulted with me at the launch of my blog, and these 20 principles feel like evolutions of that great advice. My numbers are nowhere near his (frankly, my subscriber list seems fixed lately), but my experience validates the core of what’s here: it’s all about consulting, leading to products (in my case, a bit of the other way around, via a book that arose from my website/blog). If you can afford Jon (I can’t), go for it… provided you truly are an “expert” in a given field, one that other people will pay to listen to. If you can’t, or aren’t (at least yet), just read everything he’s written, here and elsewhere.
One attractive feature of promoting digital information products is that the commissions tend to be higher than that of physical products; ranging anywhere from 10% to 50% or even higher. As an example, if someone is selling a digital information product for $500 with a 50% commission - you can earn $250 per sale. This is much higher than commissions on physical products due to the high profit margins.

Hi Sam! I love your site. We should definitely connect. I’m a school counselor and recently launched a site for parents to address pertinent teen topics. Like you, I struggle with the ultimate service I’d eventually offer on my site, but Ramsay’s idea is a great start. He’s absolutely right that people are looking for fresh content for their sites! Best of luck to you and I hope we can collaborate.
