If your digital product launched to silence, what was actually wrong?

I keep noticing a very specific indie-maker problem.

Someone builds a digital product, packages it properly, puts it on Gumroad / Lemon Squeezy / Payhip / Whop / a self-hosted checkout page, posts about it once or twice, and then...

nothing.

No sales.
No useful feedback.
No clear reason why.

The hard part is that "no sales" can mean several completely different things:

• the product is too generic;
• the buyer is unclear;
• the page does not explain the outcome;
• the screenshots, demo, or docs are missing;
• the proof/trust layer is too weak;
• the price feels wrong for the promise;
• the launch channel is wrong;
• the product is okay, but the first audience was too cold;
• the product should be a service first, not a downloadable product yet.

I am trying to turn this into a practical launch-triage framework for small digital products.

Not a "guaranteed sales" thing.
Not a motivation thread.

What did you later realize was actually wrong?

The more boring and specific, the better.
