Metadata is data that provides information about other data. In the context of web development, metadata refers to information about a web page that is not visible to users, but is used by search engines and other tools to better understand and categorize the content of the page. Examples of metadata include the page title, description, and keywords. Metadata is important for search engine optimization (SEO), as it can help improve a website's visibility in search engine results pages (SERPs).
Metadata is important for SEO as it provides context and information about the content of a web page to search engines. This helps search engines understand what a page is about, and can make it more likely to appear in relevant search results. In addition to improving visibility in search results, metadata can also help improve click-through rates by providing users with a better understanding of what they can expect to find on a page.
