The H1 Tag (<h1>) represents the main heading of a web page. It is the most important heading tag, indicating the primary topic or title of the content to both users and search engines. Think of it as the title of a book or newspaper article.
For optimal SEO and user experience, each page should ideally have only one H1 tag. This tag should contain the main keyword(s) for the page and accurately summarize its content. It helps search engines understand the page's relevance for specific queries and provides a clear entry point for users.
For example, on a blog post titled '10 Tips for Better React Performance', the H1 tag would be: <h1>10 Tips for Better React Performance</h1>. This clearly states the page's focus, making it easy for users to grasp the content at a glance and for search engines to index it appropriately.
