The first thing to understand is that HTML 5,html 5 is the core language of the fifth generation of the consortium, which we often say is HTML code. It was a new reform on the HTML4.01, or to make up for the shortcomings of the previous version. Thus, the interoperability between different user-agent is enhanced.
HTML 5 will bring in a better feature to help programmers or search engines to dissect a page's code. In the past DIV tags may be used in many pages, can be said to be flooded. In HTML 5, however, a new set of code elements is presented to describe navigation, headers, text, and so on. And this new element can help search engines better and faster to understand the content of the page.
