Header tags (H1, H2, H3, etc.) structure your content and help both users and search engines understand the hierarchy and topic of a page. Every page should have one H1 tag (usually the main title), followed by H2s for major sections and H3s for subsections. Beyond headers, content optimization means naturally including your target keyword and related terms throughout the page — in the introduction, subheadings, and body — without “keyword stuffing.” Google also values content length and depth; longer, well-organized content that thoroughly answers the search intent tends to rank better than short, thin pages.
