Richard Baxter of SEO Gadget has posted an interesting article on how the introduction of microformats, common tags, and other "structured format" standards may impact search results, and consequently, search engine marketers.

Baxter begins by actually defining those standards, explains what groundwork has been placed, and identifies early adopters and initial impressions.

Here's an excerpt:

In May 2009 Google announced their support for RDFa and Yahoo had already been working on this for a year or so via the Search Monkey application, with early example implementations in sites such as Linkedin and Yelp.

So if we’re already seeing search results changing as a result of more structured data on the web, what examples can we see to prove search engine companies intentions towards more meaningful, structured and information rich results?
