Looking ahead to HTML 5
Currently, all important content, is mostly found within either a <div> or a <span> HTML tag. I cannot emphasise the importance of content from an SEO perspective enough but here I shall focus on the HTML tags the content is found within. You may ask what is the importance of what tag is used for your content? Now there may not be a huge difference but in the future it seems that the HTML tags your content is found within may have a significant impact upon Search Engine Optimisation (SEO) and your website.
