Does <nav> have a function?

HTML5 introduces header, footer, nav, article, section and aside elements
These elements are not there to indicate an element physical position on the page, but rather the nature/meaning of the element contents.
Use these tags for better SEO score, which eventually would make the page rank higher on search engine results.
