On-Page SEO Optimization

Apply ../00-blog-writing-guardrails/SKILL.md first; its originality, accuracy, E-E-A-T, canonicalization, accessibility, plain-language, and structured-data gates apply to every post before the checks below.

1. Title tag gate

• Write a page title that is unique to the page, clear, concise, and accurately describes the page's content; do not reuse the same title across multiple pages. [GOOGLE-SEOSTART-01][GOOGLE-TITLELINK-01]
• Put the most important, page-specific information first and keep site branding minimal or reserved for the homepage; do not pad the title with repeated boilerplate that pushes unique content out of the visible, non-truncated portion. [GOOGLE-TITLELINK-01]
• Do not repeat the same word or phrase multiple times in the title in an attempt to rank for it; a few accurately descriptive terms are enough. [GOOGLE-TITLELINK-01]
• Make the page's main heading visually and structurally prominent (its own <h1>) so it is unambiguous which heading is the primary title. [GOOGLE-TITLELINK-01]

2. Meta description gate

• Write a meta description that is short, unique to that one page, and states the page's most relevant points in one or two sentences a reader can use to judge relevance before clicking. [GOOGLE-SEOSTART-01]
• Do not ship a generic or duplicated meta description across multiple pages; a missing or duplicate description forfeits control over how the page is summarized in results. [GOOGLE-SEOSTART-01]

3. Header hierarchy gate

• Use real <h1>-<h6> elements in strict nesting order that mirrors the post's actual structure, per the accessibility gate in the guardrails skill; do not skip levels or use headings only for visual size. [W3C-WCAG-01]
• Do not add headings purely to stuff in extra keyword phrasing; write each heading to describe the section that actually follows it. [GOOGLE-SEOSTART-01]
