💥 How to Optimize LLM Content for High Impact
To ensure your AI-generated content performs well, follow these best practices:
✅ Add Human Touches
Even the best LLM output may need minor edits. Personalize with your brand voice and tweak tone or phrasing as needed.
✅ Include Visual Elements
Use the generated content as a script or caption, but don’t forget to pair it with eye-catching visuals or videos.
✅ Keep Platform Nuances in Mind
What works on LinkedIn won’t work on TikTok. Be platform-specific in your prompts and edits.
✅ Test and Iterate
Track what types of posts perform best. Then tweak prompts accordingly for even better results.
⚠️ Common Mistakes to Avoid
| Mistake | Fix |
|---|---|
| ❌ Generic or vague prompts | ✅ Be clear about audience, tone, and platform |
| ❌ No CTA or engagement driver | ✅ Always include a reason for people to respond or share |
| ❌ Ignoring platform formatting | ✅ Use platform-appropriate structure (e.g., threads, lists) |
| ❌ Over-relying on AI with no edits | ✅ Always review and humanize output |
