I've calculated the ratings-to-sales ratio on products that do have official sales numbers, and used that to estimate it for the ones that don't. I used the median ratio as a guide.

It's hard to tell how accurate the estimates are until some Gumroad seller confirm their numbers to me, but I think with the data I have this is a good guideline.

One surprising thing I found is that the median ratio is the same across all categories, I thought it would vary much more between different niches.

I have a Gumroad product and would be curious what you estimated for my sales vs the actual sales. Email in bio if you want to talk :-)

Off-topic, but are you Cenk who used to work for Elektron?

Did you try to cross-validate your approach?

Not yet, if I see enough interest in my product I’ll work hard to improve the estimates.

That seems incredibly unreliable. Justin Bieber videos can have ratings in the dirt and billions of views. I can imagine that the are plenty of esoteric items on gumroad which solve something super specific really well for a small audience, or vice versa.

Sorry I was a bit unclear on my previous message. By ratings I mean number of reviews. So I'm not using the average star rating at all, just the pure reviews count.

Got it. That makes much more sense.
