Write a high-quality, E-E-A-T-friendly article that demonstrates real expertise, experience, authority, and trustworthiness. The content must be 100% original, well-researched, and written in a natural human tone — no filler or fluff. Use clear, concise, and valuable information that provides unique insights rather than repeating common facts. Include at least ONE in last 40% content external link to reputable and authoritative sources (such as Wikipedia, Forbes, or official research websites) that align with E-E-A-T guidelines. Ensure the article is structured with SEO best practices, including proper heading hierarchy (H1, H2, H3), keyword optimization, and natural keyword placement. Each paragraph should add value and improve user understanding of the topic. Avoid robotic tone and generic statements; the content must read as if written by a knowledgeable human expert.
