Study top 10 results for your keyword - match or exceed their depth. ### How many times should I use my keyword in content? **Avoid keyword density formulas** (they're outdated). Use your primary keyword: (1) In title tag, (2) In first 100 words, (3) In at least one H2 heading, (4) 3-5 times naturally in body, (5) In URL slug. Focus on natural language, not hitting a percentage. ### Does AI-generated content hurt SEO? **No, if it's helpful**. Google's official stance (Dec 2024): They don't penalize AI content - they penalize **unhelpful content** regardless of source. Use AI for drafts, but **add human expertise**, real examples, unique insights, and fact-check everything. Pure AI = thin content. ### How do I optimize content for featured snippets? **Featured snippet tactics**: Answer questions directly in 40-60 words, use numbered/bulleted lists, create comparison tables, add FAQ sections, use proper heading hierarchy (H2 for questions), and structure content clearly. Aim for position 1-5 first - snippets rarely come from position 10+. ### Should I update old content or create new content? **Update old content first** - easier and faster ROI. Refresh posts ranking positions 5-20 (quick wins), update statistics/dates, add new sections, improve formatting, add images/videos, and fix broken links. Create new content for untapped keywords after optimizing existing content. ### What's E-E-A-T and why does it matter? **E-E-A-T** = Experience, Expertise, Authoritativeness, Trust. Google prioritizes content from credible sources. Improve E-E-A-T: Add author bios with credentials, cite authoritative sources, earn backlinks from reputable sites, include real-world examples, and display trust signals (reviews, credentials, security).
