How the Changes in HTML 5 Will Affect SEO?

As a SEO expert, you are most likely interested mainly in those changes in the HTML 5 specification, which will affect your work. Here are some of them:

*Improved page segmentation. Search engines are getting smarter and there are many reasons to believe that even now they are applying page segmentation. Basically, page segmentation means that a page is divided into several separate parts (i.e. main content, menus, headers, footers, links sections, etc.) and these parts are treated as separate entries. At present, there is no way for a Web master to tell search engines how to segment a page but this is bound to change in HTML 5.
*A new * A new <section> tag. The new <section> tag can be used to identify separate sections on a page, chapter, book. The advantage is that each section can have its separate HTML heading. As with the *A new <header> tag. The new <header> tag (which is different from the head element) is a blessing for SEO experts because it gives a lot of flexibility. The <header> tag is very similar to the <H1> tag but the difference is that it can contain a lot of stuff, such as H1, H2, H3 elements, whole paragraphs of text, hard-coded links (and this is really precious for SEO), and any other kind of info you feel relevant to include.
*A new <footer> tag. The <footer> tag might not be as useful as the <header> one but still it allows to include important information there and it can be used for SEO purposes as well. The <header> and <footer> tags can be used many times on one page � i.e. you can have a separate header/footer for each section and this gives really a lot of flexibility.
*A new <nav> tag. Navigation is one of the important factors for SEO and everything that eases navigation is welcome. The new <nav> tag can be used to identify a collection of links to other pages.
