# Meta Description Generation Guide
|
||||
|
||||
AI-powered meta description generation and optimization for WordPress posts.
|
||||
|
||||
## Overview
|
||||
|
||||
The meta description generator uses AI to create SEO-optimized meta descriptions for your blog posts. It can:
|
||||
|
||||
- **Generate new meta descriptions** for posts without them
|
||||
- **Improve existing meta descriptions** that are poor quality
|
||||
- **Optimize length** (120-160 characters - ideal for SEO)
|
||||
- **Include focus keywords** naturally
|
||||
- **Add call-to-action** elements when appropriate
|
||||
|
||||
## Usage
|
||||
|
||||
### Generate for All Posts
|
||||
|
||||
```bash
|
||||
# Generate meta descriptions for all posts
|
||||
./seo meta_description
|
||||
|
||||
# Use a specific CSV file
|
||||
./seo meta_description output/all_posts_2026-02-16.csv
|
||||
```
|
||||
|
||||
### Generate Only for Missing Meta Descriptions
|
||||
|
||||
```bash
|
||||
# Only generate for posts without meta descriptions
|
||||
./seo meta_description --only-missing
|
||||
```
|
||||
|
||||
### Improve Poor Quality Meta Descriptions
|
||||
|
||||
```bash
|
||||
# Only regenerate meta descriptions with poor quality scores
|
||||
./seo meta_description --only-poor
|
||||
|
||||
# Limit to first 10 poor quality meta descriptions
|
||||
./seo meta_description --only-poor --limit 10
|
||||
```
|
||||
|
||||
### Dry Run Mode
|
||||
|
||||
Preview what would be processed:
|
||||
|
||||
```bash
|
||||
./seo meta_description --dry-run
|
||||
./seo meta_description --dry-run --only-missing
|
||||
```
|
||||
|
||||
## Command Options
|
||||
|
||||
| Option | Description |
|
||||
|--------|-------------|
|
||||
| `--only-missing` | Only generate for posts without meta descriptions |
|
||||
| `--only-poor` | Only generate for posts with poor quality meta descriptions |
|
||||
| `--limit <N>` | Limit number of posts to process |
|
||||
| `--output`, `-o` | Custom output file path |
|
||||
| `--dry-run` | Preview without generating |
|
||||
| `--verbose`, `-v` | Enable verbose logging |
|
||||
|
||||
## How It Works
|
||||
|
||||
### 1. Content Analysis
|
||||
|
||||
The AI analyzes:
|
||||
- Post title
|
||||
- Content preview (first 500 characters)
|
||||
- Excerpt (if available)
|
||||
- Focus keyword (if specified)
|
||||
- Current meta description (if exists)
|
||||
|
||||
### 2. AI Generation
|
||||
|
||||
The AI generates meta descriptions following SEO best practices:
|
||||
- **Length**: 120-160 characters (optimal for search engines)
|
||||
- **Keywords**: Naturally includes focus keyword
|
||||
- **Compelling**: Action-oriented and engaging
|
||||
- **Accurate**: Clearly describes post content
|
||||
- **Active voice**: Uses active rather than passive voice
|
||||
- **Call-to-action**: Includes CTA when appropriate
|
||||
|
||||
### 3. Quality Validation
|
||||
|
||||
Each generated meta description is scored on:
|
||||
- **Length optimization** (120-160 chars = 100 points)
|
||||
- **Proper ending** (period = +5 points)
|
||||
- **Call-to-action words** (+5 points)
|
||||
- **Overall quality** (minimum 70 points to pass)
|
||||
|
||||
### 4. Output
|
||||
|
||||
Results are saved to CSV with:
|
||||
- Original meta description
|
||||
- Generated meta description
|
||||
- Length of generated meta
|
||||
- Validation score (0-100)
|
||||
- Whether length is optimal
|
||||
- Whether it's an improvement
|
||||
|
||||
## Output Format
|
||||
|
||||
The tool generates a CSV file in `output/`:
|
||||
|
||||
```
|
||||
output/meta_descriptions_20260216_143022.csv
|
||||
```
|
||||
|
||||
### CSV Columns
|
||||
|
||||
| Column | Description |
|
||||
|--------|-------------|
|
||||
| `post_id` | WordPress post ID |
|
||||
| `site` | Site name |
|
||||
| `title` | Post title |
|
||||
| `current_meta_description` | Existing meta (if any) |
|
||||
| `generated_meta_description` | AI-generated meta |
|
||||
| `generated_length` | Character count |
|
||||
| `validation_score` | Quality score (0-100) |
|
||||
| `is_optimal_length` | True if 120-160 chars |
|
||||
| `improvement` | True if better than current |
|
||||
| `status` | Generation status |
|
||||
|
||||
## Examples
|
||||
|
||||
### Example 1: Generate All Missing Meta Descriptions
|
||||
|
||||
```bash
|
||||
# Export posts first
|
||||
./seo export
|
||||
|
||||
# Generate meta descriptions for posts without them
|
||||
./seo meta_description --only-missing
|
||||
```
|
||||
|
||||
**Output:**
|
||||
```
|
||||
Generating AI-optimized meta descriptions...
|
||||
Filter: Only posts without meta descriptions
|
||||
Processing post 1/45
|
||||
✓ Generated meta description (score: 95, length: 155)
|
||||
...
|
||||
|
||||
✅ Meta description generation completed!
|
||||
Results: output/meta_descriptions_20260216_143022.csv
|
||||
|
||||
📊 Summary:
|
||||
Total processed: 45
|
||||
Improved: 42 (93.3%)
|
||||
Optimal length: 40 (88.9%)
|
||||
Average score: 92.5
|
||||
API calls: 45
|
||||
```
|
||||
|
||||
### Example 2: Fix Poor Quality Meta Descriptions
|
||||
|
||||
```bash
|
||||
# Only improve meta descriptions scoring below 70
|
||||
./seo meta_description --only-poor --limit 20
|
||||
```
|
||||
|
||||
### Example 3: Test with Small Batch
|
||||
|
||||
```bash
|
||||
# Test with first 5 posts
|
||||
./seo meta_description --limit 5
|
||||
```
|
||||
|
||||
### Example 4: Custom Output File
|
||||
|
||||
```bash
|
||||
./seo meta_description --output output/custom_meta_gen.csv
|
||||
```
|
||||
|
||||
## Meta Description Quality Scoring
|
||||
|
||||
### Scoring Criteria
|
||||
|
||||
| Criteria | Points |
|
||||
|----------|--------|
|
||||
| Optimal length (120-160 chars) | 100 |
|
||||
| Too short (< 120 chars) | 50 - (deficit) |
|
||||
| Too long (> 160 chars) | 50 - (excess) |
|
||||
| Ends with period | +5 |
|
||||
| Contains CTA words | +5 |
|
||||
|
||||
### Quality Thresholds
|
||||
|
||||
- **Excellent (90-100)**: Ready to use
|
||||
- **Good (70-89)**: Minor improvements possible
|
||||
- **Poor (< 70)**: Needs regeneration
|
||||
|
||||
### CTA Words Detected
|
||||
|
||||
The system looks for action words like:
|
||||
- learn, discover, find, explore
|
||||
- read, get, see, try, start
|
||||
- and more...
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Before Generation
|
||||
|
||||
1. **Export fresh data** - Ensure you have latest posts
|
||||
```bash
|
||||
./seo export
|
||||
```
|
||||
|
||||
2. **Review focus keywords** - Posts with focus keywords get better results
|
||||
|
||||
3. **Test with small batch** - Try with `--limit 5` first
|
||||
|
||||
### During Generation
|
||||
|
||||
1. **Monitor scores** - Watch validation scores in real-time
|
||||
2. **Check API usage** - Track number of API calls
|
||||
3. **Use filters** - Target only what needs improvement
|
||||
|
||||
### After Generation
|
||||
|
||||
1. **Review results** - Open the CSV and check generated metas
|
||||
2. **Manual approval** - Don't auto-publish; review first
|
||||
3. **A/B test** - Compare performance of new vs old metas
|
||||
|
||||
## Integration with WordPress
|
||||
|
||||
### Manual Update
|
||||
|
||||
1. Open the generated CSV: `output/meta_descriptions_*.csv`
|
||||
2. Copy generated meta descriptions
|
||||
3. Update in WordPress SEO plugin (RankMath, Yoast, etc.)
|
||||
|
||||
### Automated Update (Future)
|
||||
|
||||
Future versions may support direct WordPress updates:
|
||||
```bash
|
||||
# Not yet implemented
|
||||
./seo meta_description --apply-to-wordpress
|
||||
```
|
||||
|
||||
## API Usage & Cost
|
||||
|
||||
### API Calls
|
||||
|
||||
- Each post requires 1 API call
|
||||
- Rate limited to 2 calls/second (0.5s delay)
|
||||
- Uses Claude AI via OpenRouter
|
||||
|
||||
### Estimated Cost
|
||||
|
||||
Approximate cost per 1000 meta descriptions:
|
||||
- **~$0.50 - $2.00** depending on content length
|
||||
- Check OpenRouter pricing for current rates
|
||||
|
||||
### Monitoring
|
||||
|
||||
The summary shows:
|
||||
- Total API calls made
|
||||
- Cost tracking (if enabled)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### No Posts to Process
|
||||
|
||||
**Problem:** "No posts to process"
|
||||
|
||||
**Solutions:**
|
||||
1. Export posts first: `./seo export`
|
||||
2. Check CSV has required columns
|
||||
3. Verify filter isn't too restrictive
|
||||
|
||||
### Low Quality Scores
|
||||
|
||||
**Problem:** Generated metas scoring below 70
|
||||
|
||||
**Solutions:**
|
||||
1. Add focus keywords to posts
|
||||
2. Provide better content previews
|
||||
3. Try regenerating with different parameters
|
||||
|
||||
### API Errors
|
||||
|
||||
**Problem:** "API call failed"
|
||||
|
||||
**Solutions:**
|
||||
1. Check internet connection
|
||||
2. Verify API key in `.env`
|
||||
3. Check OpenRouter account status
|
||||
4. Reduce batch size with `--limit`
|
||||
|
||||
### Rate Limiting
|
||||
|
||||
**Problem:** Too many API calls
|
||||
|
||||
**Solutions:**
|
||||
1. Use `--limit` to batch process
|
||||
2. Wait between batches
|
||||
3. Upgrade API plan if needed
|
||||
