## Common JSON-LD Syntax Errors

### Trailing Commas

**Error**: Invalid JSON syntax
```json
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Title",  ← Trailing comma here
}
```

**Fix**: Remove the comma after the last property
```json
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Title"
}
```

### Missing Required Quotes

**Error**: Property names must be quoted
```json
{
  @context: "https://schema.org"
}
```

**Fix**: Quote all property names
```json
{
  "@context": "https://schema.org"
}
```

### Incorrect Date Format

**Error**: Invalid date format
```json
{
  "datePublished": "01/15/2024"
}
```

**Fix**: Use ISO 8601 format
```json
{
  "datePublished": "2024-01-15T08:00:00+00:00"
}
```

### Relative URLs Instead of Absolute

**Error**: Relative URLs are not allowed
```json
{
  "image": "/images/photo.jpg"
}
```

**Fix**: Use absolute URLs
```json
{
  "image": "https://example.com/images/photo.jpg"
}
```

### Incorrect Array Syntax

**Error**: Multiple values not in array
```json
{
  "image": "url1.jpg", "url2.jpg"
}
```
