# SEO Optimizer for WordPress
Production-ready Go application that automatically optimizes WordPress blog posts for SEO using Claude AI.
## Features
- **Autonomous Optimization**: Automatically selects and optimizes old blog posts
- **Budget-Conscious**: Single comprehensive Claude API call per post (~€0.05/post)
- **Multi-Language Support**: Alternates between English and Spanish (Polylang)
- **Comprehensive SEO**: Meta tags, content improvements, internal linking, FAQ blocks
- **Draft Revisions**: Creates draft revisions for human approval (never auto-publishes)
- **Smart Selection**: Respects cooldown periods and content quality criteria
- **REST API**: Manual triggers and status monitoring
- **Production-Ready**: Docker, Kubernetes, graceful shutdown, structured logging
## Architecture
```

```
## Quick Start
### Prerequisites
- Go 1.21+
- Docker (optional)
- WordPress with:
- Application Password enabled
- Polylang plugin
- RankMath SEO plugin
- REST API accessible
### Setup
1. **Clone and configure**:
```bash
git clone <repository>
cd WPSideKick
make dev-setup
```
2. **Edit credentials**:
```bash
# Edit .env with your credentials
nano .env
```
Required:
- `WP_APP_PASSWORD`: Generate in WordPress → Users → Profile → Application Passwords
- `CLAUDE_API_KEY`: Get from https://console.anthropic.com/
3. **Install dependencies**:
```bash
make deps
```
4. **Run locally**:
```bash
make run
```
## Configuration
### Environment Variables
| Variable | Description | Default |
|----------|-------------|---------|
| `WP_APP_PASSWORD` | WordPress Application Password | **Required** |
| `CLAUDE_API_KEY` | Claude API key | **Required** |
| `OPTIMIZATION_INTERVAL_HOURS` | Hours between optimizations | 2.5 |
| `LOG_LEVEL` | Logging level (INFO/DEBUG) | INFO |
| `API_PORT` | REST API port | 8080 |
| `WEBHOOK_URL` | Optional webhook for notifications | - |
### Configuration File
Copy `configs/config.example.yaml` to `configs/config.yaml` and customize:
```yaml
wordpress:
base_url: "https://your-blog.com"
username: "admin"
claude:
model: "claude-sonnet-4-20250514"
max_tokens: 4096
temperature: 0.3
scheduler:
enabled: true
interval_hours: 2.5
languages: ["en", "es"]
optimization:
min_content_length: 500
min_age_days: 30
max_age_days: 365
reoptimization_cooldown_days: 365
storage:
base_path: "./data/optimizations"
```
## Docker Deployment
### Docker Compose (Recommended)
```bash
# Build and start
make docker-build
make docker-run
# View logs
make logs
# Stop
make docker-stop
```
### Docker Run
```bash
docker build -t seo-optimizer .
docker run -d \
--name seo-optimizer \
-p 8080:8080 \
-e WP_APP_PASSWORD="your-password" \
-e CLAUDE_API_KEY="your-key" \
-e OPTIMIZATION_INTERVAL_HOURS=2.5 \
seo-optimizer
```
## Kubernetes Deployment
```bash
# Edit secrets in deployment.yaml first
kubectl apply -f deployments/kubernetes/deployment.yaml
# Check status
kubectl get pods -l app=seo-optimizer
kubectl logs -f deployment/seo-optimizer
# Port-forward for local access
kubectl port-forward svc/seo-optimizer 8080:8080
```
## REST API
### Endpoints
#### Health Check
```bash
curl http://localhost:8080/api/v1/health
# Response: {"status":"ok","version":"1.0.0"}
```
#### Manual Optimization
```bash
curl -X POST http://localhost:8080/api/v1/optimize \
-H "Content-Type: application/json" \
-d '{"post_id": 123, "language": "es"}'
# Response: {"job_id":"uuid","status":"accepted"}
```
#### Check Status
```bash
curl http://localhost:8080/api/v1/status/uuid
# Response: {"status":"completed","post_id":123,...}
```
#### Pending Reviews
```bash
curl http://localhost:8080/api/v1/pending
# Response: {"count":2,"records":[...]}
```
#### Optimization Details (by Post ID)
```bash
curl http://localhost:8080/api/v1/optimization/123
# Response: { ... optimization record ... }
```
#### Apply Draft
```bash
curl -X POST http://localhost:8080/api/v1/apply-draft \
-H "Content-Type: application/json" \
-d '{"draft_post_id": 456}'
# Response: {"status":"applied","message":"Draft applied to original post and draft deleted"}
```
### Optimization Records (File Storage)
Optimizations are stored on disk for audit and review:
- Base path: `storage.base_path` (default `./data/optimizations`)
- Subfolders: `pending/`, `applied/`, `rejected/`, `skipped/`
- Files: `{post_id}_{unix_timestamp}.json` containing the full Claude response
## How It Works
### Post Selection
The optimizer selects posts based on:
- **Age**: Last modified between 30 and 365 days ago
- **Content**: >= 500 words
- **Cooldown**: Not optimized in last 12 months
- **Status**: Published only
- **Order**: Oldest first
### Optimization Process
1. **SEO Meta**: Optimized title (50-60 chars) and description (150-160 chars)
2. **Content Changes**: Keyword injection, heading improvements, technical updates
3. **Internal Links**: 3-8 relevant internal links with descriptive anchors
4. **FAQ Block**: 4-6 questions in RankMath format (if appropriate)
5. **Validation**: Fact-checking and broken link fixes
6. **Draft Creation**: WordPress draft revision (requires manual approval)
### Cost Tracking
- Model: Claude Sonnet 4.5
- Pricing: $3/1M input tokens, $15/1M output tokens
- Est. per post: 8K input + 2K output ≈ $0.054 (€0.05)
- Budget: €10/month ≈ 200 posts
- Interval: 2.5 hours ≈ 10 posts/day ≈ 300 posts/month
## Monitoring
### Logs
```bash
# Docker Compose
docker-compose logs -f
# Kubernetes
kubectl logs -f deployment/seo-optimizer
# JSON format (default)
{
"time":"2026-01-24T10:30:00Z",
"level":"INFO",
"msg":"Optimization completed",
"post_id":123,
"cost_usd":0.054,
"changes":8,
"links":5,
"duration_seconds":45.2
}
```
### Health Check
```bash
# HTTP
curl http://localhost:8080/api/v1/health
# Docker
docker inspect --format='{{.State.Health.Status}}' seo-optimizer
```
## Development
### Build
```bash
# Local build
make build
# Production build (optimized)
make build-prod
# Run with debug logging
make run-debug
```
### Testing
```bash
# Run all tests
make test
# With coverage
make test-coverage
# Quick tests
make test-quick
```
### Code Quality
```bash
# Format code
make fmt
# Lint (requires golangci-lint)
make lint
# All checks
make all
```
## Troubleshooting
### WordPress Connection Issues
**Problem**: "WordPress API error: status 401"
**Solution**:
1. Verify WordPress Application Password is correct
2. Check WordPress REST API is accessible: `curl https://your-blog.com/wp-json/wp/v2/posts`
3. Ensure username and password are properly set in .env
### Claude API Errors
**Problem**: "Claude API error: status 401"
**Solution**:
1. Verify Claude API key is correct
2. Check API key has sufficient credits
3. Test API key: `curl https://api.anthropic.com/v1/messages -H "x-api-key: YOUR_KEY"`
### No Posts Selected
**Problem**: "No eligible posts found for optimization"
**Possible causes**:
- All posts are too recent (< 120 days old)
- All posts were recently optimized (< 90 days ago)
- Posts don't meet minimum word count (500 words)
**Solution**:
- Adjust `max_age_days` or `reoptimization_cooldown_days` in config
- Check post modification dates in WordPress
### Budget Exceeded
**Problem**: Costs exceeding €10/month
**Solution**:
- Increase `interval_hours` (e.g., 3.0 or 4.0)
- Reduce optimization frequency
- Monitor costs in logs: `grep "cost_usd" logs/*.log`
## Security
- **No Auto-Publish**: Creates draft revisions only
- **Local API**: No authentication (assumes local/trusted network)
- **Credentials**: Use environment variables, never commit secrets
- **Non-Root**: Docker runs as non-root user (UID 1000)

```
http://localhost:8080/api/v1
```
## Endpoints
### 1. Health Check
Check if the API server is running.
```bash
GET /health
```
**Response:**
```json
{
"status": "ok",
"version": "1.0.0"
}
```
---
### 2. Optimize Post
Manually trigger optimization for a specific post.
```bash
POST /optimize
Content-Type: application/json
{

```
**Response:**
```json
{
"id": "uuid-string",
"post_id": 123,
"language": "es",
"status": "completed",
"started_at": "2025-01-24T10:00:00Z",
"ended_at": "2025-01-24T10:02:30Z",
"summary": "Optimization completed successfully"
}
```
**Example:**
```bash
curl http://localhost:8080/api/v1/status/abc-123-def
```

"questions": [...]
}
}
}
]
}
```
**Example:**
```bash
curl http://localhost:8080/api/v1/pending
```
---
### 5. Get Optimization Details
Get detailed optimization information for a specific post.
```bash
GET /optimization/{post_id}
```
**Parameters:**
- `post_id` (int): Original WordPress post ID
**Response:**
```json
{
"post_id": 123,
"original_post_id": 123,
"draft_post_id": 456,
"post_title": "How to Test Helm Charts in Production",
"language": "en",
"optimized_at": "2025-01-24T10:00:00Z",
"status": "pending",
"optimization": {
"seo_meta": {...},

"faq_block": {...},
"validation": {...},
"summary": "Enhanced SEO with 8 keyword injections..."
}
}
```
**Example:**
```bash
curl http://localhost:8080/api/v1/optimization/123
```
---
### 6. Apply Draft
Apply a pending draft to the original published post and delete the draft.
```bash
POST /apply-draft
Content-Type: application/json
{
"draft_post_id": 456
}
```
**Parameters:**
- `draft_post_id` (int, required): WordPress draft post ID to apply
**Response:**
```json
{
"status": "applied",
"message": "Draft applied to original post and draft deleted"
}
```
**Example:**
```bash
curl -X POST http://localhost:8080/api/v1/apply-draft \
-H "Content-Type: application/json" \
-d '{"draft_post_id": 456}'
```
Or use the helper script:
```bash
./scripts/apply-draft.sh 456
```
---
## Workflow
### Typical Optimization Workflow
1. **Trigger Optimization** (automatic via scheduler or manual via API)
```bash
POST /optimize {"post_id": 123, "language": "en"}
```
- Creates a draft copy with optimized content
- Original post stays published
- Optimization record saved to storage
2. **Review Pending Drafts**
```bash
GET /pending
```
- Lists all draft posts waiting for review
- Shows what changes were made
3. **Check Optimization Details** (optional)
```bash
GET /optimization/123
```
- See detailed changes, FAQ blocks, internal links, etc.
4. **Review in WordPress Admin**
- Go to Posts → Drafts
- Find the draft post (linked to original via meta)
- Review changes in WordPress editor
5. **Apply Draft** (when satisfied)
```bash
POST /apply-draft {"draft_post_id": 456}
```
- Copies draft content to original post
- Keeps original post published
- Deletes the draft
- Updates storage status to "applied"
---
## Error Responses
All endpoints return appropriate HTTP status codes:
- `200 OK`: Success
- `202 Accepted`: Request accepted (async processing)
- `400 Bad Request`: Invalid input
- `404 Not Found`: Resource not found
- `500 Internal Server Error`: Server error
Error response format:
```
HTTP/1.1 400 Bad Request
post_id must be positive
```
---
## File Storage
Optimization records are stored in the file system at the configured `storage.base_path`:
```
./data/optimizations/
├── pending/ # Drafts waiting for review
│ ├── 123_1737715200.json
│ └── 456_1737718800.json
├── applied/ # Successfully applied optimizations
│ └── 789_1737629200.json
└── rejected/ # Manually rejected drafts
```
Each file contains the complete optimization record including:
- Post metadata
- Optimization details
- SEO meta
- Content changes
- FAQ blocks
- Internal links
- Validation results
---
## Configuration
Enable/disable the API server in `config.yaml`:
```yaml
api:
enabled: true
port: 8080
storage:
base_path: "./data/optimizations"
```
---
## Security
**IMPORTANT**: The API has no authentication and is intended for local access only.
- Do not expose the API to the internet
- Use a reverse proxy with authentication if needed
- Run on localhost or behind a firewall
---
## Monitoring
Check server logs for detailed operation information:
```bash
# View logs in JSON format
tail -f logs/optimizer.log | jq
# Filter for API-related logs
tail -f logs/optimizer.log | jq 'select(.component == "api")'
```

**Optimization Guidelines**:
1. **SEO Meta Optimization**:
- Title: Front-load primary keyword, make it unique and compelling
- Description: Include target keyword, benefits, and subtle call-to-action
- Both must be different from current ones (show improvement)
- Follow character limits strictly
2. **Content Optimization**:
- **Moderate changes only**: Don't rewrite entire sections unless critically outdated
- Add target keywords naturally where they fit (keyword density: 1-2%)
- Improve H2/H3 headings for clarity and keyword inclusion
- Fix awkward phrasing or unclear explanations
- Add technical context where it helps LLM understanding
- Update deprecated terms, old version numbers, obsolete practices
- Maintain the author's technical voice and depth
3. **Internal Linking** (3-8 links per post):
- Prioritize posts in same category or related topics
- Use descriptive anchor text (avoid "click here", "this post")
- Vary anchor text (don't repeat same phrase)
- Insert links naturally in context (not forced)
- Prefer linking to comprehensive guides or deep technical posts
- Reasoning: explain topic relevance and SEO benefit
4. **FAQ Block (RankMath)** (4-6 questions):
- Create FAQ only if content benefits from structured Q&A
- Focus on questions users actually search for (use question keywords)
- Answers: 40-80 words, clear, direct, technically accurate
- Include product names, technical terms, and version info where relevant
- Use HTML formatting: <strong> for emphasis, <code> for commands, <a> for links
- Questions should cover: What, Why, How, When, Best practices
5. **Validation & Fact-Checking**:
- Verify technical claims against official documentation:
* Kubernetes: kubernetes.io
* TIBCO: docs.tibco.com
* Proxmox: pve.proxmox.com
* Ceph: docs.ceph.com
- Check for outdated version numbers, deprecated APIs, old practices
- Validate external links (simulate check: 404s, moved pages, redirects)
- If uncertain about accuracy, mark as "uncertain" and flag for review
- Prioritize official sources over blog posts or Stack Overflow
6. **Summary** (write in {{if eq .Language "es"}}Spanish{{else}}English{{end}}):
- List each type of change made (meta, content, links, FAQ, validation)
- Explain reasoning for major updates
- Flag any concerns requiring manual review
- Note any technical claims you're uncertain about
- Provide overall assessment of post quality and improvements made
**Critical Rules**:
- NEVER change the post slug (URL must remain stable)
- NEVER remove substantial content without strong justification
- ALWAYS provide "reason" fields for transparency
- ALWAYS write summary in {{if eq .Language "es"}}Spanish{{else}}English{{end}} for human reviewer
- Keep technical depth and accuracy (this is an expert audience)
- Maintain original author's voice and style
- Return ONLY valid JSON, no markdown formatting, no text outside JSON
