To achieve a top listing with a search engine’s result page for a specific keyword or phrase for a specific web page or website, you need to analyze the structure of that page. The term “content is king” applies to some extent, but how the content is built, the structure of the XHTML is really important in making the content index to the top of the SERPs (Search Engine Result Pages).

Consider the behavior of a person reading a newspaper. Not all pages will be looked at in any detail, scanning headlines, key areas that stand out on a page or keywords of interest is what the reader will hone into. A web page is no different. Not only do you have to have good, original, relevant to the topic (key words), but you must "type-set" that content into a logical format that is easy to understand quickly. Once the reader is "hooked", more details within the article, info should be available either in finer print, links, images, or other relevant media for a web page to pull and keep the reader active.

This is where semantic structure of the page and content is very important. With the advent of mobile technology, page structure is even more important for a wider range of users to access your information. One tool by the World Wide Web Consortium (W3C) has this semantic extraction tool to help you analyze your page’s semantic structure. Firefox has several add-ons that allow you to view a web pages semantic structure, usually based on the XHTML header tags <h1></h1>...<h6></h6>, <p></p> and other structural elements.

SEO best practices start at the foundation of a page and the semantic structure plays an important role along with good content, properly placed keywords, meta data, links, relevant media, XHTML element placement, usage and fine-tuning with their corresponding attributes.
