Best Practices

Writing Effective Posts

1. Hook first: Lead with the most interesting point
2. Be concise: Every word should add value
3. Use threads for long content: Break into digestible chunks
4. Add context: Don't assume readers know the topic
5. Include CTA: Ask questions, invite replies

What to Avoid

• Excessive hashtags (more than 3)
• All caps (reads as shouting)
• Broken links
• Posting too frequently (spam behavior)
• Controversial content without context
