I've been using Google checkout for about five months now. I want users to see my perfect feedback in case they are a bit worrisome. Is there a way to link directly with the google system on your site? I know that Google Checkout ratings are visible on Google product seach but my products have been in "Base" for a long time and quite honestly I don't think I will ever show up in Google products.
The best way is to find any one of your products in product search. Under your name will be your rating with a link to user feedback. I would copy the url and link to it from whatever you need to. Other than that, I don't know of any way to display the rating.
Good advice, I'd add a link to the ratings/product page and maybe include a few quotes of good customer feedback next to the link.
