Do you have experience of getting sales from Gumroad's discover page?
That is, apart from sales that come from the product's website and other direct links.
By discover page, this is what I mean - https://gumroad.com/discover?query=Ebook
Gumroad needs to improve this. I have tried to find stuff on the discovery page and not been successful. For example, if you try an empty search you get nothing if you not logged in. This is from a buyers perspective, so a reason why sales are unlikely to happen from the 'discover' page.
