## Property-Specific Verification

### 1. ✅ areaServed vs geographicArea

**Research Findings:**

- `areaServed` is the **correct property** for WebApplication (and Service types)
- `geographicArea` is **NOT valid** for BusinessAudience type
- `areaServed` accepts: Country, State, GeoCircle, or Text
- **Best Practice:** Use Country array for multiple countries

**Our Implementation:**

```json
"areaServed": [
    {
        "@type": "Country",
        "name": "Deutschland"
    },
    {
        "@type": "Country",
        "name": "Österreich"
    },
    {
        "@type": "Country",
        "name": "Schweiz"
    }
]
```

**Verification:** ✅ **CORRECT** - Following Schema.org best practices

---

### 2. ✅ BusinessAudience Properties

**Research Findings:**

- Valid properties for BusinessAudience:
  - `audienceType` ✅ (we use this)
  - `geographicArea` ❌ (NOT valid - this was the error)
  - `requiredMinAge` ❌ (NOT valid - this was the warning)
  - `audienceSize` ❌ (NOT valid - this was the error)

**Our Implementation:**

```json
"audience": {
    "@type": "BusinessAudience",
    "audienceType": "Restaurant-Betreiber, Einzelhandel, Hotel-Manager, Schichtbetriebe"
}
```

**Verification:** ✅ **CORRECT** - Removed invalid properties, kept only valid `audienceType`

---

### 3. ✅ availableLanguage vs inLanguage

**Research Findings:**

- `inLanguage` ✅ - Valid for WebApplication (we use this)
- `availableLanguage` ❌ - NOT a valid property for WebApplication
- **Best Practice:** Use `inLanguage` for WebApplication (single language) or `inLanguage` array for multiple

**Our Implementation:**

```json
"inLanguage": "de-DE"
```

**Verification:** ✅ **CORRECT** - Using valid `inLanguage` property, removed invalid `availableLanguage`

---

### 4. ✅ FAQPage Implementation

**Research Findings:**

- **Best Practice:** Use JSON-LD only (not microdata)
- **Best Practice:** Each Question must have `name` and `acceptedAnswer` with `text`
- **Best Practice:** Avoid duplicate schema declarations

**Our Implementation:**

- ✅ Single FAQPage declaration in JSON-LD
- ✅ All questions have `name` property
- ✅ All answers have `text` property
- ✅ Removed HTML microdata (was causing duplicate)

**Verification:** ✅ **CORRECT** - Following Schema.org best practices
