Maximize Your SEO Potential with Server Side Tracking: A Comprehensive Guide

// Beispiel: Event-Tracking in React Native App
import { trackServerSideEvent } from './tracking';

const handlePurchase = async (orderData) => {
  // Event wird an Server gesendet
  await trackServerSideEvent({
    event: 'purchase',
    userId: user.id,
    properties: {
      orderId: orderData.id,
      value: orderData.total,
      currency: 'EUR',
      items: orderData.items
    },
    timestamp: new Date().toISOString()
  });
};

// TrackingManager.swift
class ServerSideTrackingManager {
    static let shared = ServerSideTrackingManager()
    private let apiEndpoint = "https://tracking.your-domain.com/events"

    func track(event: String, properties: [String: Any]) {
        var request = URLRequest(url: URL(string: apiEndpoint)!)
        request.httpMethod = "POST"
        request.setValue("application/json", forHTTPHeaderField: "Content-Type")

        let eventData: [String: Any] = [
            "event": event,
            "userId": UserDefaults.standard.string(forKey: "userId"),
            "properties": properties,
            "timestamp": ISO8601DateFormatter().string(from: Date()),
            "platform": "iOS",
            "appVersion": Bundle.main.infoDictionary?["CFBundleShortVersionString"]
        ]

        request.httpBody = try? JSONSerialization.data(withJSONObject: eventData)

        URLSession.shared.dataTask(with: request).resume()
    }
}

// Usage
ServerSideTrackingManager.shared.track(
    event: "product_viewed",
    properties: [
        "productId": "123",
        "category": "Electronics",
        "price": 299.99
    ]
)

// ServerSideTracker.kt

            put("userId", getUserId())
            put("properties", JSONObject(properties))

            put("platform", "Android")
            put("appVersion", BuildConfig.VERSION_NAME)
        }

        val request = Request.Builder()
            .url(apiEndpoint)
            .post(json.toString().toRequestBody("application/json".toMediaType()))
            .build()

        client.newCall(request).enqueue(object : Callback {

}

// Usage
