Your cards are beautiful! I love the gold embossing.
I'm not great at outside marketing myself. Everything good that has happened to my shop happened sort of by accident. But I work at my shop a little everyday, so maybe that's my best advice.
I do, however, have some ways you can improve views:
1. Add more to your title descriptions. Think of what words a buyer might type in the box above to find items like yours. Then,
2. Repeat some of those key words in your tags.
3. Your tags should be multiple words. (wedding card, mr and mrs card, hand embossed, gold embossing, etc.)
4. Your cards are so elegant, but the background you're using isn't. It might be difficult to find a background that white cards will photograph well on, and that might be a question for another thread.
I hope this helps!
