Glad to see ranking on Bing and Yahoo picks up. For photo to portrait, portrait from photo etc., the rankings are still very low. Wait for Bing and Yahoo to cache the pages.

In general, I think Magento platform is pretty friendly for SEO. Wordpress is the same. I didn't do anything for my old website phototoportrait.us, but it keeps its ranking of keyword "photo to portrait painting" very high, around No. 5-6 of first page.
