How adding Micro data to HTML tags can optimize your site for search engine spiders
Why use Micro Data?
PROBLEM:
Search engines lack the ability to fully understand the content/context of the data embedded in your web page
THE DREAM:
If only there was a way to enable the web crawlers/spiders used by search engines to better understand your content and display it in a useful, relevant way...
Micro Data
By adding additional tags to your HTML, content can be contextually indexed by web crawlers

Graphical Example of Hierarchy
Simple Code Example
