|
|
1. Generate a CORE PERSONA that captures the user's unique writing style, brand voice, and content characteristics
|
|
2. Generate PLATFORM-SPECIFIC ADAPTATIONS for each target platform
|
|
3. Ensure consistency across all personas while optimizing for each platform's unique characteristics
|
|
4. Include specific recommendations for content structure, tone, and engagement strategies
|
|
|
|
PLATFORM OPTIMIZATIONS:
|
|
- LinkedIn: Professional networking, thought leadership, industry insights
|
|
- Facebook: Community building, social engagement, visual storytelling
|
|
- Twitter: Micro-blogging, real-time updates, hashtag optimization
|
|
- Blog: Long-form content, SEO optimization, storytelling
|
|
- Instagram: Visual storytelling, aesthetic focus, engagement
|
|
- Medium: Publishing platform, audience building, thought leadership
|
|
- Substack: Newsletter content, subscription-based, personal connection
|
|
|
|
Generate personas that are:
|
|
- Highly personalized based on the user's actual content and business
|
|
- Platform-optimized for maximum engagement
|
|
- Consistent in brand voice across platforms
|
|
- Actionable with specific writing guidelines
|
|
- Scalable for content production
