Official Google Webmaster Central Blog: Introducing Rich Snippets - 0 views

  •  
    Google "Rich Snippets" is a new presentation of HTML snippets that applies Google's algorithms to highlight structured data embedded in web pages. Rich Snippets give end-users convenient summary information about their search results at a glance. Google is currently supporting a very limited subset of data about reviews and people. When searching for a product or service, users can easily see reviews and ratings, and when searching for a person, they'll get help distinguishing between people with the same name. It's a simple change to the display of search results, yet our experiments have shown that users find the new data valuable. For this to work though, both Web-masters and Web-workers have to annotate thier pages with structured data in a standard format. Google snippets supports microformats and RDFa. Existing Web data can be wrapped with some additional tags to accomplish this. Notice that Google avoids mention of RDF and the W3C's vision of a "Semantic Web" where Web objects are fully described in machine readable semantics. Over at the WHATWG group, where work on HTML5 continues, Google's Ian Hickson has been fighting RDFa and the Semantic Web in what looks to be an effort to protect the infamous Google algorithms. RDFa provides a means for Web-workers, knowledge-workers, line-of-business managers and document generating end-users to enrich their HTML+ with machine semantics. The idea being that the document experts creating Web content can best describe to search engine and content management machines the objects-of-information used. The google algorithms provide a proprietary semantics of this same content. The best solution to the tsunami of conten the Web has wrought would be to combine end-user semantic expertise with Google algorithms. Let's hope Google stays the RDFa course and comes around to recognize the full potential of organizing the world's information with the input of content providers. One thing the world desperatel
