Digital download drawing worksheet gets views but no sales - what clarity issues should I check first?

I sell digital printable art/drawing-study downloads and I am trying to diagnose views with no sales.

I am not looking for a shop critique or promotion. I am trying to understand what experienced Etsy sellers would check first for a digital PDF worksheet-type product.

Current things I am reviewing:

- whether the first image makes the exact deliverables obvious

- page count/value perception

- PDF/JPG/ZIP clarity

- mobile download confusion

- whether the title sounds like wall art instead of a practice worksheet

- whether the previews show enough without giving away the whole product

For digital downloads, what has usually caused views without conversion in your experience?
