I've been designing Figma/Canva templates for a while now, and the difference between a template that gets a 1-star "looks nothing like the preview" review and one that gets shared unprompted usually comes down to 3 things:

1. Component structure, not just static layers. If someone has to manually reposition every element when they swap a photo, the template feels broken. Auto-layout (Figma) or smart groups (Canva) aren't optional polish — they're the actual product.

2. A realistic color/font swap path. Most buyers aren't going to keep your brand colors. Build templates around a single set of color/text styles so a full re-theme takes 5 clicks, not 50.

3. Restraint in the preview. The biggest trust-killer is a preview image that's more polished than the actual editable file (extra shadows, custom fonts nobody can access, stock photos not included). Show exactly what they're buying.

Building out a small Figma UI + Social Kit right now with this philosophy baked in — happy to answer questions if you're building your own template shop too.
