Of course, including keywords in the product page title/description and associated feed.  But what else?Would be interested to hear your thoughts on:  PageRank of destination page  how product pricing affects placement  how age of page affects placement  imagesEDIT: meant to say - the above are just some things that I'm wondering about, but any other general non-obvious tips also appreciated!
Google Shopping: beyond the basics, how can I optimize for high placement?

As a rule of thumb I always supply as much data as possible into all the fields available. Note: I don't mean keyword cram, I mean just supply as much detail as you can about the product. This has served me well to date.Read the official Google Guidelines for more.I once read an (unverified) article stating that Google shopping does not take the target page into consideration and only the supplied feed. I'm not sure this is true, but even if it were you would still want a well built website with proper titles and content to compete in the standard web search regardless which does mitigate this point.One thing that is apparent when I search for items using Google Shopping is that the items near the top always have lots of user ratings. I don't think it is a coincidence. It is hard to prove this as in the world of Google nothing is ever confirmed or denied.
