H1 tag is an important part of HTML coding and provides a content hierarchy within a webpage. It indicates the most important piece of content on the page, allowing readers to focus on the crucial information.
H1 tags appear as large text titles at the top of webpages, search engines, or post summaries, and they can profoundly affect SEO performance when used properly. It can also help improve accessibility for those using screen reading software by providing titles that succinctly describe the main topic of each page or post. That way, users can easily navigate the web page without searching through paragraphs of text.
H1 tags should only be used once per page, as using them more than once can lead to confusing messaging and poor SEO results.
