Bob,  
When you do a search from the home page, you'll only bring up cards that you have your name in the keywords or title somewhere.  The search will not take you to an artist's store.  
 We just had the discussion on whether to use your store name in the keywords and came to the conclusion that it's not a good idea if you use common terms in your store name like "valley" or "visions" as you have in your name.  If you have cards with 'visions' or 'valley' as the theme, then you're OK!
Someone could find you from the home page by doing an artist search either for your name or your store name.  
Best,  Randy

I thought you couldn't use your store name in the keywords...
