5 Years of Google Rich Snippets

Today marks the fifth anniversary of the official introduction of Google rich snippets, announced in a Webmaster Central blog post of May 12, 2009.

Google had been experimenting with "enhanced listings" as far back as December 2008, with review and product rich snippets being spotted in results for Yelp, Citysearch, CNET, TripAdvisor and Download.com. The May 2009 announcement provided these enhanced listings with an official name, and explained how these results were generated.

The announcement post extolled the virtue of giving "users convenient summary information about their search results at a glance" through rich snippets, and provided information about the markup formats that were used to generate rich snippets – intially microformats and RDFa.

The number of rich snippet types displayed in Google has grown steadily over the past five years. I've compiled a list of these rich snippets, along with a rendering of the example snippet that accompanied each Google announcement. This inventory may not be wholly comprehensive, but I believe you'll find the most important rich snippet types listed.

Many rich snippets, like breadcrumbs or video, weren't officially announced but made their appearance in the search results over time. And are the innumerable stand-out results in Google "rich snippets," "search verticals," or simply evolved search results? To-may-to, to-mat-oh, in my opinion.

And there's been many technical tweaks and infrastructure changes at Google in support of rich snippets, even if these haven't resulted in the generation of new rich snippets or changes to the appearance of existing rich snippets. Milestones include the launch of the Rich Snippets Testing Tool (October 2009, renamed the Structured Data Testing Tool in September 2012), support for microdata (March 2010), and – of course – the launch of schema.org (June 2011).

The introduction of rich snippets into Google search results marked the beginning of the end of "ten blue links." Rich snippets both conceptually and visually paved the way for Knowledge Graph and even, perhaps, signaled the point at which Google ceased to be a simple provider of links to other websites and set its sights on becoming a purveyor of answers in its own right.

Google Rich Snippets really change the search ball game, for the better of course.

Nice look back on snippets. With social media structured data it is becoming more difficult to eliminate redundancy and focus in on what is really needed to cover both search engines and social networks. For example og:description, <meta itemprop="description" and the <meta name="description" all serve different purposes, but figuring this out takes a lot of study!

Thanks Anne. Yyou’re quite right, with more and more types of structured data being made available for different purposes it’s difficult to avoid duplication and errors.

Slides 21 and 36 of my deck on “digital presence optimization,” embedded at the end of the post of the same name, elucidate further the point you make with your “description” example.

More and more I’ve come to look at structured data markup more generically as property-value pairs than as data targeting a specific data consumer like a search engine or specific social network, and now often create tables that help me to consistently supply the same values for the same sorts of properties. That doesn’t necessarily eliminate or reduce redundancy, but it does help ensure that the different bases are covered – efficiently and consistently – for different data consumers.

Being a huge fan of structured data I always use Rich Snippet, especially Schema in my projects and got really good results, indeed. Most of the time it makes the SERP listing stand out from the other listings and results in higher CTR. Always recommended to the site owners. Good info shared and thanks for the same.
