Rich snippets are one of the best ways to improve search results. Basically the idea behind rich snippets is to tell the search engine spiders EXACTLY what each part of the website does. So addresses get the itemprop=”address” tag added. This can be done through a span or div element. The span element could look like this:
<span itemprop="address">123 Sycamore Ave.</span>
This tells the search engines what parts of a website are important for certain queries (“What is that business’s address?). Try tagging multiple parts of your website, starting with the content and working around the various areas such as
the header and footer.

<div itemscope itemtype="http://data-vocabulary.org/Person"> My name is <span itemprop="name">Bob Smith</span> but people call me <span itemprop="nickname">Smithy</span>. Here is my home page: <a href="http://www.example.com" itemprop="url">www.example.com</a> I live in Albuquerque, NM and work as an <span itemprop="title">engineer</span> at <span itemprop="affiliation">ACME Corp</span>. </div>
