Google endorses microformats

Google has announced support for Rich Snippets. This is information you add to your web pages using "microformats" to help Google understand specific data. For example, Google understands vcard tags. I think it's likely that they understood those long before this announcement, but now they have also added hreview for reviews and say that they intend to extend this idea.

I think it's great, but not everyone is so enthusiastic. Some think that spammers will abuse this or that it will only benefit large sites. While that all could be true, I don't see any reason NOT to make use of this - anything that helps Google understand your pages better has to help you no matter what anyone else is doing.

I've started doing this on pages here. I've updated recent reviews and added microformat tags to the Linux and Unix Consultants page. You can "View Source" there and look for "vcard" to see how this is done. For an example of using hReview, look at the source for Take Control of the Mac Command Line with Terminal. You'll see these tags in the source:

 <div class="hReview">
 <div class="item">
 

Those tell Google that this is a review. Later on, I tag the title with a "fn" tag. Notice that these are done "inline".

 <p><i><span class="fn">
 Take Control of the Mac Command Line with Terminal</span></i> 
 is the answer.
 <span class="summary">Joe Kissell leads you step by step from
 knowing absolutely nothing to having confident control of Mac OS
 X Terminal and the bash shell.   If you have been fearful of the
 OS X command line, this is where you want to start.</span></p>
 

I use a few more tags to identify the reviewer, the date, and a rating:

 <span class="reviewer">Tony Lawrence</span> 
 <span class="dtreviewed">2009/05/04</span> 
 Rating:  <span class="rating">4.5</span></p>
 

This is simple enough, but unfortunately, some of the examples Google provides are inaccurate and potentially confusing. I'd pay more attention to Microformats.org pages for guidance.
