Do search engines and/or screen readers give any importance to the new tags in HTML5?

Sometimes I think I will use HTML5 with the help of JavaScript, but what is the benefit if search engines and/or screen readers will not understan开发者_如何转开发d the new tags?

<header> and <div class="header"> are the same thing if <header> has no benefit for SEO and screen readers.

I haven’t heard of search engines paying attention to HTML5 tags yet, nor of any screen readers with HTML5 support.

But if/when screen readers do support HTML5, the new document outlining rules should make it easier for users to navigate HTML5 documents that use the sectioning and heading elements.

Companies that make screen readers might be waiting for there to be more HTML5 pages before implementing HTML5 support. It could be a chicken-and-egg problem.

Of course, there are new tags in HTML5 other than <header> that offer advantages unrelated to search engines and screen readers, e.g.

• <canvas> (you get a 2D drawing surface, for like graphs and stuff)
• <video> (you get to use videos without having to use a Flash video player)
