H1based

H1based refers to a web development practice where the main heading of a webpage, typically denoted by the HTML tag `<h1>`, is used for the primary title or topic of the content. This is a fundamental aspect of Search Engine Optimization (SEO) and web accessibility. Search engines like Google utilize the `<h1>` tag to understand the core subject matter of a page, which influences its ranking in search results. For users, the `<h1>` tag visually presents the most important information at the top, providing a clear and immediate understanding of the page's purpose. A well-structured page usually contains only one `<h1>` tag. While other heading tags like `<h2>`, `<h3>`, etc., are used for subheadings and hierarchical organization of content, the `<h1>` is reserved for the singular, overarching theme. Misusing or omitting the `<h1>` tag can negatively impact both SEO performance and user experience, making it a crucial element in effective web design. Developers often ensure that the text within the `<h1>` tag is relevant, descriptive, and includes key keywords that users might search for.
