    Kerry – extremely good blog post.

    I have been working with a developer recently who has already adopted the HTML5 Tags and Schema.org markup language on their new websites. I think this is a topic worthwhile being ahead of the game (or at least keeping up with it) rather than doing this 2 years down the line when it becomes clearer of the SEO benefits.

    Will duly follow you on Twitter :)

    Adobe just announce that it drop the flash for mobile so basically HTML5 is going defiantly to be the king!!!

    I can’t see where html5 has a benefit over flash with regard to SEO. I keep seeing this statement bot no actual reasoning or evidence behind it.

    If you do flash like stuff in html5 then it’s JavaScript. A language very similar to what flash is written in. So it has the same fundamental issues that make it hard to crawl. How does html5 solve that issue? A pile of crap in a new box is….a pile of crap!

    I’m not saying html5 is bad, but don’t expect Google to suddenly learn how to interpret your complex animated pages just because you switched them from flash to html5 code. They might find it slightly easier to get the text from the content, but to understand how the text is used a complex job, and the easiest solution is to ignore it. A simile case, where text is used in a JavaScript based tabbing system can get the tabs text ignored. Don’t expect content in JavaScript, hidden data or AJAX calls to do brilliant, unless your FaceBook or Disqus ;-)

    html5 does have some good features for SEO, which you pointed out:

    The extra semantic tags such as may help the search engines to confirm the true content of a page.

    Semantic markup is not technically html5, but microdata (schema.org) looks like the syntax that will dominate and is html5 specific.

    It does bloat up code a bit, however I hope it’s bloating will add valuable information for the search engines and not just formatting and styling that traditionally bloat pages..

    HTML5 technologies have a lot to offer outside of semantic tags. One of the plagues of the internet is the use of # or #! within URL structures. An awful implementation of this is seen on billboard.com. Check out how 2 URLs exist for the same content and how polluted they can be when you enter any page other than the homepage.

    The HTML5 History API (which is actually JavaScript) solves this problem because we can update the browser’s history stack while dynamically loading content (updating sections of content on a page; think photo galleries).

    One more item to mention is HTML5 Local Storage (again, JavaScript). Perfect use of it would be for mobile sites. Generally, the cache limit on smartphones is very small so users are consistently downloading necessary components. With Local Storage, we can increase the limit of cacheable objects to provide a responsive experience.

    Going back to semantic markup, is anyone talking about the benefit of rich snippets? CTR + Traffic + Links = Rankings? :)

    Listen up to what Shay mentioned: It is recent information and will make a BIG difference re advantages of HTML5 support of video. Adobe just announced it is discontinuing Flash for mobile, with desktop and other devices presumably to follow.

    Also, as Kerry mentioned, sites like Vimeo and YouTube now offer both Flash and HTML5.Most users like the lighter HTML5 versions.

    Other than HTML5 for video and its appeal for users, it seems like HTML5 could be a real annoyance initially! Tony describes some reasons. I think that despite the fact that schema.org is a standard agreed upon by Google, Yahoo and Microsoft/ Bing, there will be an uneven time interval when they will need to learn how to interpret your HTML5 compliant pages with the new tags. Assuming you get it all correct, with validated markup. I don’t have any evidence to cite, just experience in dealing with standards introductions and transitions.

    Here’s a recent sort-of-example: Google+ implementation. It is new, it is Google’s own product, and it is still in development. Issues due to a single page component, the Google+ feature, are tolerable. But I wouldn’t want ALL of my webpage, and SEO, to go through that at the same time!

    The one other concern I have is that HTML4 (and predecessors) were drafted by W3C and finalized at some point. HTML5 is apparently a “living standard”, a versionless one, thus called HTML, and led by WHATWG (no idea what that means). W3C is still working on their HTML5 snapshot version, getting close to finalizing, and WHATWG works with W3C. But I do wonder how webpage designers and website owners are going to fare with a “living standard”. Static HTML4 (and predecessors) were a known value, could be taken for granted even when other things like search engine algorithms changed.

    Thank you Kerry, for an excellent post. I learned a lot from reading this. Actually, quite a bit more than from trying to read WHATWG and W3C docs, but that’s cause you are writing on a level appropriate for my needs. I appreciate it!

    I’m looking for a reliable source better to understand HTML5 browser compatibility. Is there a source to show which browsers (ex. IE7, IE8, Chrome 11) choke on HTML5 and what their market penetration currently is?
