Schema markup is a form of structured data that helps search engines better understand the content on your website. It provides context to your content by labeling the different elements on your page such as products, recipes, reviews, events, and more. By doing so, it makes it easier for search engines to crawl and index your site, which can help improve your search engine rankings.
