Schema markup is a type of structured data that helps search engines better understand and display website content. For restaurants, implementing schema markup can significantly enhance their appearance in search results, leading to rich snippets that include information such as menus, prices, ratings, and operating hours. These enhanced search results not only make a restaurant more visually appealing in SERPs but also provide valuable information to potential diners at a glance. This increased visibility and information can lead to higher click-through rates and more informed customers, ultimately resulting in increased reservations and foot traffic.
