H2 and H3 tags form part of the HTML heading hierarchy, coming right after the main H1 tag. They function as subheadings (H2) and sub-subheadings (H3) to break down your content into digestible sections. This not only helps in structuring your content but also plays a vital role in guiding the reader and search engines through the topic efficiently.

Why are Heading Tags Important for SEO?

Bullet Points: Benefits of Heading Tags

Heading tags like H2 and H3 are essential tools in SEO for several reasons. They make your content more readable, thereby enhancing user experience. By properly segmenting your content, you offer both human readers and search engines a roadmap to the most important points of your article. This, in turn, improves the chances of your page ranking higher in search engine results.

Role of Keywords in SEO

Keywords are the building blocks of any SEO strategy. They are the terms that users type into search engines, looking for answers to their queries. By aligning your content with relevant keywords, you increase its visibility on search engines, thus attracting a more targeted audience.
