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 <article> tag. The new <article> tag is probably the best addition from a SEO point of view. The tag allows to mark separate entries in an online publication, such as a blog or a magazine. It is expected that when articles are marked with the tag, this will make the HTML code cleaner because it will reduce the need to use <div> tags. Also, probably search engines will put more weight on the text inside the tag as compared to the contents on the other parts of the page.

* 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 <article> tag, it can be presumed that search engines will pay more attention to the contents of separate sections. For instance, if the words of a search string are found in one section, this implies higher relevance as compared to when these words are found all across the page or in separate sections.

* 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

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.

As you see, the new tags follow the common structure of a standard page and each of the parts (i.e. header, footer, main section) has a separate tag. The tags we described here, are just some (but certainly not all) of the new tags in HTML 5, which will affect SEO in some way. For instance, <audio>, <video> or <dialogue> tags are also part of the HTML 5 standard and they will allow to further separate the content into the adequate categories. There are many other tags but they are of relatively lower importance and that is why they are not discussed.
