In short: our systems are pretty good at parsing the common kinds of HTML-like markup, including the various flavors of HTML and XHTML. As far as I know, our crawling and indexing systems currently don’t do anything special for HTML5, so there is no “bonus” for using HTML5 constructs, but similarly also generally no downside. That said, most of the pages with HTML5 markup that I’ve seen tend to be very clean – with little “cruft” and unnecessary elements. While having clean markup isn’t something that our algorithms explicitly look for, we occasionally see pages that are almost unparseable. Also, clean markup makes it much easier to maintain the website, easier to add new elements like microformats, and frequently makes the pages more portable across a variety of browsers and devices. So with that in mind, there’s nothing holding you back (from a search point of view) from creating an awesome site in HTML5 :)<\/p><\/blockquote>\n
