I'm repurposing content but analyze: should I go platform-native only? Map each platform's native format preference: TikTok = vertical video, Twitter = text, etc. Show me if cross-posting is killing my reach. Calculate: does platform-specific content outperform repurposed by enough to justify the extra work? Give me the native vs. repurpose decision: these platforms punish repurposing, these don't care. Include: which platforms demand native content, how algorithm detects repurposed content, and when laziness (repurposing) costs you reach.
