"HTML5 is a new version of HTML and XHTML. The HTML5 draft specification defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML."
From http://html5.org
As we know, Xhtml 1.0 and 1.1 is a new age for web pages, XHTML documents need to be well-formed, they can be parsed using standard XML parsers .But if you see source code of many website, you will find it's always DIV tags, many DIVs. If just see the html source code, we dont know which div tag is what, and search engine either.
Thanks GOD, we have HTML5.
HTML5 have some new functions and tags, some browsers do not support all functions, but we still can use the new tags for good seo html document.
For example, in XHTML, we will have:
<div id="header"></div>
But in HTML5, we have:
<header></header>
And we have:
<aside></aside>
<article></article>
<section></section>
etc...
DIV just a NORMAL container, search engines dont know id="header" or how impotant about this DIV.
In good tags, search engine will find the right container of you important content, not many DIVs.
If you warry about browser compatibility is not good, please check the website what you see now in different browsers. We use HTML5.
