A "head line" typically refers to the main title or heading of a news article, blog post, or other written content. It is designed to grab the reader's attention and provide a brief summary of the article's main point. Effective head lines are often concise, engaging, and informative, helping readers quickly understand the topic being discussed. In journalism, head lines play a crucial role in attracting readers and encouraging them to read further. They often include keywords related to the content, making it easier for readers to find the article through search engines. A well-crafted head line can significantly impact the article's reach and engagement.
