I might have more precisely said: I imagined myself to be creating a BCC clone of sorts with www.makecupcakewrappers.com but found that trying your style of SEO/Content-Creation often resulted in ugly repetitive pages, where creating genuinely new content is expensive and labor intensive due to the graphical nature of the product.
But I didn't quite realize that going in. That's why I point out how elegantly conducive your product is to Scaleable Content Creation.
If you are using words in your cupcake wrappers, maybe find some way to make them searchable text (SVG for instance). Also something like theme groups (birthday, Halloween, etc.) might help. Also magnetic text as an alternative to a word cloud.
