SEO Content: Content Optimization

Guides on-page content optimization: word count, heading keywords, keyword density vs stuffing, multimedia, tables, and lists. Complements heading-structure (structure) and content-strategy (planning).

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope

• Word count: Length by content type; quality over length
• H2 keywords: Placement, quantity, variation
• Keyword density vs stuffing: Natural use; avoid manipulation
• Multimedia: Images, tables, lists for structure and Featured Snippets. See featured-snippet for snippet-specific optimization.

Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md or .cursor/product-marketing-context.md exists, read it for target keywords and content type.

Identify:

1. Content type: Article, guide, listicle, pillar, news
2. Target keyword: Primary and secondary
3. Competitors: Top 10 average length and structure — see competitor-research

Word Count

Google does not rank by word count. Length should match search intent and topic depth. A 1,000-word post that satisfies intent can outrank a 3,000-word thin piece.

Reference Ranges by Content Type

| Content type | Word count | Notes | |--------------|-------------|-------| | News / announcements | 300–600 | Time-sensitive; concise | | Standard articles / how-tos | 1,000–1,500 | Single topic; actionable | | Listicles / guides | 1,200–2,000 | "Top 10," "Best X" | | Pillar / cornerstone | 2,000–3,500+ | Comprehensive; cluster hub | | Competitive keywords | 2,000–2,500 | Top 10 avg ~2,400 words |

Strategy

1. Analyze top 10 for target keyword — average length and depth
2. Match intent — informational often needs ~40% longer than transactional
3. Value over padding — each section must add genuine value; avoid fluff
4. Comprehensive coverage — answer the query and related questions

H2 Heading Keywords

Placement

• Primary keyword: Include naturally in at least one H2 when relevant
• Related keywords: Use LSI and long-tail in other H2s for topical coverage
• Avoid stuffing: Headings must stay clear and readable; organic placement only

Quantity

• No strict limit — one H2 per major section; structure follows content
• Typical article: 4–8 H2s; pillar: 8–15+ H2s
• Hierarchy: H1 → H2 (major sections) → H3 (subsections); don't skip levels

Best Practices

| Practice | Purpose | |----------|---------| | Descriptive H2s | Search engines understand context; users scan | | Answer-first | Place direct answer in first 40–50 words after H2 for Featured Snippets; see featured-snippet | | Keyword variation | Use related terms; avoid repeating exact phrase in every H2 | | Logical flow | H2s outline the article; support topical authority |

Keyword Density vs Keyword Stuffing

Definitions

| Term | Meaning | |------|---------| | Keyword density | (Keyword count / Total words) × 100; a metric, not a ranking factor | | Keyword stuffing | Excessive, unnatural repetition to manipulate rankings; black-hat |

Current Guidance

• Keyword density is not a direct ranking factor — Google has stated since 2011 that repetition alone doesn't improve rankings
• Reference range: 0.5%–1.5% for most content; some sources cite up to 2.5%
• Use density mainly to avoid stuffing — if density exceeds ~2–3% and reads unnaturally, reduce
• Prioritize natural placement: title, H1, first 100 words, 1–2 H2s, body; avoid forced repetition

How to Avoid Stuffing

• Write for users first; keywords should fit naturally
• Use synonyms, related terms, and question phrasing
• If a sentence sounds awkward with the keyword, rewrite
• Monitor: if every paragraph repeats the exact phrase, simplify

Multimedia: Images, Tables, Lists

Images

| Practice | Purpose | |----------|---------| | Alt text | Descriptive; include keyword when natural; accessibility | | File names | Descriptive (e.g. seo-checklist-2025.jpg) | | Compression | WebP; optimize for LCP | | Captions | Relevant to topic; can support Featured Snippets; see featured-snippet | | Original over stock | Unique images signal E-E-A-T — see eeat-signals |

Tables

• Use for: Comparisons, stats, specs, "X vs Y"
• Semantic HTML: <table>, <thead>, <tbody>, clear column headers
• Featured Snippets: ~6% of snippets are tables; optimize headers with target keywords. See featured-snippet
• Mobile: Responsive; avoid horizontal scroll when possible
• Data quality: No empty cells; consistent units; accurate, current data

Lists: Ordered vs Unordered

| Type | Use case | SEO / Snippet | |------|----------|---------------| | Ordered (<ol>) | Steps, rankings, sequences, "Top 10" | List snippets (~19% of Featured Snippets); how-to; see featured-snippet | | Unordered (<ul>) | Non-sequential items, features, options | Bullet snippets; definitions, options |

Best practices:

• Use semantic <ol> and <ul>; avoid divs styled as lists
• Answer-first: For snippet targets, put the direct answer in the first 40–50 words after the heading
• Concise items: List items should be scannable; expand in body if needed
• Logical order: Ordered lists = sequence matters; unordered = no sequence

GEO / AI Citation

Answer-first (direct answer in first 40–60 words after H2) supports both Featured Snippets and GEO. For article-level GEO (TL;DR, Key Takeaways, QAE pattern), see article-page-generator and generative-engine-optimization. For Featured Snippet formats and optimization, see featured-snippet.
