What is Semantic SEO? Semantic SEO refers to the practice of optimizing your content for collective topics that are connected, rather than single keywords. That means that when you create digital content which you want to rank for a certain keyword and answer a specific query, you will anticipate the questions that would naturally come to a reader after the initial query. By including the answers to these questions as well, your content has a chance to rank for a variety of relevant keywords, and ultimately a chance to rank for a longer period of time.
