Many businesses are quietly updating their websites in the background. Why? Because today's search engine results page competition is fierce, and as a result, SEO strategies have evolved to a new model that many content-focused websites are employing.
The old topic-based model for SEO has been replaced with a topic cluster approach, in which a single "pillar" page serves as the centerpiece of information for an entire subject area while numerous content pages that are related to that same subject link back to the pillar page and to each other. The pillar page is linked to in order to signal search engines that it is an authority on the subject, and over time, the page may rank higher for the subject it covers. At its core, the topic cluster model is a method of organizing a site's content pages using a more clear and deliberate architecture.
