Structured citation Just like the listings in the old school phone books, a structured citation is basically a business listing online. From online databases such as social media sites, Yelp, Yext, and the online Yellowpages, structured citations include not only your business name, but also your address and phone number (NAP). NAP consistency is one of Google’s main ranking factors. Unstructured citation The difference between structured citation and unstructured is that unstructured is a reference to your business. These references may happen in articles, descriptions, captions, reviews, and online forums. Unstructured citations effectiveness is built around relevance of the industry, local relevance, and domain authority.
