Schema markup is a type of code added to a webpage that helps search engines better understand the content on that page.
For example, it can tell search engines whether a page is about a recipe, a product, an event, or something else. This added information can improve how the page appears in search results sometimes showing extra details like star ratings, prices, or event dates.
Because of this, schema markup is considered an important part of SEO optimization, as it can enhance visibility and improve how search engines interpret your content.
