Two negatives with using the Google Shopping feeds for rich snippets.
1. AC does not support external imaging for Product Feeds. (This excludes us immediately)
2. Google wants canonical tags on product pages. (This also excludes us)
Note: Product page canonical tags can now be implemented by adding
<link rel="canonical" ##ITEMFULLURL## /> to each product's Head
Tags (meta) box.
"For Google to make use of Merchant Center feeds for rich snippets, you should also use the rel=”canonical” link element
on your product pages. By adding rel=”canonical” to your pages, Google
can match the URLs in your feed to the pages found by our crawler."
The benefit of hard coded RDFa Rich Snippets should be seen across all search engines soon, regardless of feed availability, or quality. The semantic web is coming, so we might as well jump on board.
