|
|
|
|
**2026 Algorithm Notes:**
|
|
- Video content (Reels) prioritized - 60% of content
|
|
- Link posts penalized (98% of viewed posts have no external links)
|
|
- Groups content receives algorithmic boost
|
|
- Meaningful engagement > vanity metrics
|
|

## 2. Thai Language Considerations
|
|
|
|
### 2.1 Character Counting
|
|
|
|
| Platform | English | Thai |
|
|
|----------|---------|------|
|
|
| Facebook post | 63,206 chars | Same (Thai chars count individually) |
|
|
| Facebook headline | 40 chars | 40 chars (ไทย = 3 chars) |

|
|
| Google Ads description | 90 chars | 90 chars |
|
|
| Twitter | 280 chars | 280 chars (Thai properly counts) |
|
|
|
|
**Thai Character Properties:**
|
|
- Thai script: Unicode range U+0E00-0E7F
|
|

## Appendix: AI Content Humanization
|
|
|
|
### Avoiding Robotic Patterns
|
|
|
|
**Common AI Mistakes:**
|
|
- Overuse of transition words (furthermore, additionally)
|
|
- Generic openings (In today's world, It's important to note)
|
|
- Perfectly structured paragraphs
|
|
- Lack of specific examples
|
|
- No personal voice or opinion
|
|
|
|
**Humanization Techniques:**
|
|
|
|
1. **Vary sentence structure:** Mix short punchy + longer flowing
|
|
2. **Add specific details:** Names, dates, real examples
|
|
3. **Include opinions/takes:** "Here's what I think..."
|
|
4. **Use contractions:** Don't → don't (when appropriate for tone)
|
|
5. **Rhetorical questions:** Engage reader directly
|
|
6. **Cultural references:** Thai context, local examples
|
|
7. **Imperfections OK:** Occasionally fragment sentences
|
|
8. **Active voice:** Most of the time
|
|
|
|
**Thai-Specific:**
|
|
- Add Thai idioms (สำนวน) appropriately
|
|
- Use casual markers (ครับ/ค่ะ) correctly
|
|
- Reference Thai current events
|
|
- Include Thai-specific examples
|
