• Create content clusters: Build topical authority by covering your niche comprehensively
• Use AI for efficiency, not replacement: AI tools speed up research and drafting, but human editing ensures quality
• Prioritize technical basics: Fast loading, mobile-friendly, proper indexing — get these right before investing in content at scale
• Measure everything: Google Search Console is free and provides the data you need to make informed decisions
