Anyone know what factors Google uses in determining "relevance" of products submitted to Froogle? Obviously product name/description but what else: overall relevance of domain, price, how long it has been submitted, how often a link is clicked for a given search? The reason I ask is, in my product niche, the domains in the SERPS a general Google search of the product name v. the domains in the Froogle SERP are completely different. Curious to see if others have had the same experience or know any sure fire Froogle SEO tips.
We have yet to discover what ranks some items higher than others in Google Base, but it would be useful to know. Another Google secret I think!
