Google’s Rich snippets for I, grabbed my attention to create a new advancement in syndicating reviews, products and prices from various areas. I will need to investigate further if it can be integrated into a personal favourite of mine, Google Base.
The best is the extra links within content that add relevance and user ranking to a product or service. If integrated with adsense a marketeer could mark up comment keywords which show up, adding a new dimension to PPC. As well, these snippits can add a long tail aspect in SEO searching. Nice one Google!
