Stratégie de SEO YouTube et de Miniatures

Act as a YouTube SEO and CTR (Click-Through Rate) Specialist. My video topic is [Insert Topic] in the [Insert Niche] niche. Build a complete packaging strategy for maximum discovery. Please include: * An SEO-optimized title strictly under 60 characters, with the main keyword placed near the front * 3 completely different thumbnail concepts, each using a different emotional trigger (curiosity, FOMO, shock) * Include short, punchy text overlays (max 3 words each) * A full keyword-rich video description with formatted timestamps (chapters) and a clear CTA * 10 highly relevant tags (mix of broad keywords and long-tail phrases) * A/B test variations for the strongest thumbnail concept to improve click-through rate
