On April 17th, Google announced they were rolling out updates to Rich Snippets that includes support of product rich snippets globally. For any webmasters out there that haven’t implemented this simple HTML markup on their site, this should be your last call.
(If you’re unfamiliar with Rich Snippet Markup, here is the 60 Second Intro from Google)
Fortunately for all of us, Google, Bing, and Yahoo have agreed to support a common standard in micro data formatting. The http://schema.org/ resource outlines most of the various tags that can be added, and provides clear documentation.
Google has also provided a Rich Snippet Tool to allow developers to test exactly how their markup will appear in the Google SERP’s before pushing it live.
On Ecommerce sites rich snippets can include price, reviews, star ratings, brand, categories, and breadcrumbs. One study showed a 150% improvement in Organic CTR.
Content Based Websites aren’t left out though. You can add the rel=author tag to show your picture and name in the search results next to the article. Barry Swartz at SearchEngineRoundtable outlines how authors are getting a better CTR simply by changing their picture!
