hReview is a specific microformat intended to designate review content in a webpage and allow it to be easily found and indexed by search engines like Google and other web applications. Microformats is a system which uses existing XHTML and HTML tags to pass information in a systematic way by describing what the content is for search engines and other web users. hCalendar – for events, hCard – for contact information, and hProduct – for products are examples of other specific microformats. Microformats do not affect how your web page renders in a browser, they simply make your source code smarter and have an impact on how web applications and tools collect, understand, and process the information in your web pages.
The hReview microformat is broken into several different properties including the date/time the review was written, a summary of the review, the author, the item being reviewed, a rating, a permalink to the review, and others.

When using the hReview microformat and its properties in your source code you will be at an advantage in the Google SERPS. You will be feeding information to Google to use its Rich Snippets feature. Google defines this feature as ‘giving users convenient summary information about their search results at a glance’. If you search ‘piccolos italian restaurant’ on Google the number one result includes a rich snippet summary of the reviews available on the City-Search site. As the example demonstrates the rich snippets allow a surfer to search for a product and/or service and then see a quick summary of the reviews of that product on any particular site. This data will only be pulled from your web site if you are implementing the hReview microformat in your source code.
