A subheadline is a secondary headline that provides additional context or information about the main headline. It often appears directly below the main title and helps to clarify the content of an article, blog post, or advertisement. Subheadlines can engage readers by summarizing key points or highlighting important details, making it easier for them to decide whether to read further. In journalism and marketing, effective subheadlines can enhance the overall message and improve readability. They serve as a tool to break up text and guide readers through the content. By using keywords and phrases, subheadlines can also improve search engine optimization (SEO), making it easier for audiences to find the material online.
