Theme JSON is a configuration file introduced in WordPress 5.8 that allows theme developers to manage and customize the appearance and functionality of a website through a standardized JSON format. This file streamlines the process of setting global styles, such as typography and color schemes, and enhances block-based theme development, thereby improving website performance and user experience. In the context of SEO and marketing, leveraging Theme JSON can lead to more consistent branding and faster load times, which are critical factors for search engine rankings and user engagement.
