Bid Menurut Cuaca

Permintaan untuk produk dan layanan tertentu sangat bervariasi bergantung pada cuaca. Misalnya, pengguna jauh lebih cenderung menelusuri informasi tentang taman hiburan pada hari yang panas dan cerah daripada saat dingin dan hujan. Perusahaan taman hiburan mungkin ingin meningkatkan bid mereka saat cuaca bagus, tetapi melakukannya setiap hari akan membutuhkan banyak pekerjaan manual. Namun, dengan skrip Google Ads, Anda dapat mengambil informasi cuaca secara terprogram dan menyesuaikan bid dalam hitungan menit.

Skrip ini menggunakan Google Spreadsheet untuk menyimpan daftar kampanye dan lokasi yang terkait. Panggilan ke OpenWeatherMap API dibuat untuk setiap lokasi dan kondisi cuaca dihitung menggunakan beberapa aturan dasar. Jika aturan bernilai true (benar), pengganda bid lokasi yang sesuai akan diterapkan ke penargetan lokasi untuk kampanye.

Cara kerjanya

Skrip bekerja dengan membaca data dari {i>spreadsheet<i}. {i>Spreadsheet <i}terdiri dari tiga {i>sheet<i} individu:

1. Data kampanye

Serangkaian aturan menentukan pengubah bid yang akan diterapkan pada kampanye saat kondisi cuaca terpenuhi. Berikut adalah kolom yang wajib diisi:

• Nama Kampanye: Nama kampanye yang akan diubah.
• Lokasi Cuaca: Lokasi yang kondisi cuacanya akan diperiksa.
• Kondisi Cuaca: Kondisi cuaca tempat aturan ini akan diterapkan.
• Pengubah Bid: Pengubah bid lokasi yang akan diterapkan jika kondisi cuaca terpenuhi.
• Terapkan Pengubah Ke: Apakah pengubah bid hanya diterapkan ke target geografis kampanye yang cocok dengan Lokasi Cuaca atau ke semua target geografis kampanye.
• Enabled: Tentukan Yes untuk mengaktifkan aturan dan No untuk menonaktifkannya.

Contoh

Contoh berikut memiliki tiga kampanye.

Kampanye Pengujian 1 menggambarkan skenario penggunaan umum. Kampanye tersebut menargetkan Boston, MA dan memiliki dua aturan:

1. Terapkan pengubah bid 1.3 jika cuaca di Jakarta, MA adalah Sunny.
2. Terapkan pengubah bid 0.8 jika cuaca di Jakarta, MA adalah Rainy.

Kampanye Pengujian 2 memiliki aturan bidding yang sama dengan Kampanye Pengujian 1, tetapi menargetkan Connecticut.

Kampanye Pengujian 3 juga menggunakan aturan bidding yang sama, tetapi menargetkan Florida. Karena aturan cuaca untuk Florida dipetakan ke seluruh negara bagian, yang bukan lokasi yang ditargetkan secara eksplisit oleh kampanye, 'Apply Modifier To' ditetapkan ke All Geo Targets sehingga kota yang menjadi target kampanye terpengaruh.

Poin Penting: Jika beberapa aturan cocok untuk kampanye dan lokasi tertentu, aturan pencocokan terakhir akan menang.

2. Data cuaca

Sheet ini menunjukkan kondisi cuaca yang digunakan dalam sheet data Kampanye. Kolom berikut wajib ada:

• Nama Kondisi: Nama kondisi cuaca (misalnya, Sunny).
• Suhu: Suhu dalam Fahrenheit.
• Presipitasi: Hujan, dalam milimeter, selama 3 jam terakhir.
• Angin: Kecepatan angin, dalam mil per jam.

Sheet yang ditampilkan di atas mendefinisikan dua kondisi cuaca:

1. Sunny: Suhu antara 65 dan 80 derajat Fahrenheit, curah hujan di bawah 1 mm hujan dalam tiga jam terakhir, dan kecepatan angin kurang dari 5 mpj.
2. Rainy: Presipitasi di atas 0 mm hujan dalam tiga jam terakhir dan kecepatan angin kurang dari 10 km/jam.

Kondisi cuaca

Saat menentukan kondisi cuaca, tetapkan nilai sebagai berikut:

• below x: Nilai yang ditentukan adalah below x (misalnya below 10)
• above x: Nilai yang ditentukan adalah above x (misalnya above 70)
• x to y: Nilai yang ditentukan adalah antara x dan y, inklusif (misalnya, 65 to 80)

Jika Anda membiarkan sel kosong, parameter tersebut tidak akan dipertimbangkan dalam penghitungan. Jadi dalam contoh kita, karena kondisi cuaca Rainy memiliki kolom suhu yang kosong, suhu tidak akan dipertimbangkan saat menghitung kondisi cuaca ini.

Kondisi cuaca digabungkan dengan fungsi AND saat menghitung kondisi cuaca. Untuk contoh ini, kondisi cuaca Sunny dievaluasi sebagai berikut:

const isSunny = (temperature >= 65 && temperature <= 80) && (precipitation < 1) && (wind < 5);

3. Data lokasi cuaca

Sheet ini menentukan lokasi cuaca yang digunakan dalam sheet data Kampanye, dan terdiri dari dua kolom:

• Lokasi Cuaca: Ini adalah nama lokasi cuaca, seperti yang dipahami oleh OpenWeatherMap API.
• Kode Target Geografis: Ini adalah kode target geografis, sebagaimana dipahami oleh Google Ads.

Skrip ini memungkinkan Anda menentukan beberapa kode target geografis untuk satu lokasi cuaca karena lokasi cuaca tidak selalu sedetail opsi penargetan yang tersedia di Google Ads. Pemetaan satu lokasi cuaca ke beberapa lokasi geografis dapat dilakukan dengan membuat beberapa baris dengan lokasi cuaca yang sama, tetapi dengan kode geografis berbeda untuk setiap baris.

Untuk contoh ini, ada tiga lokasi cuaca yang ditentukan:

1. Boston, MA: Kode geografis 10108127
2. Connecticut: Kode geografis 1014778, 1014743, dan 1014843, yang sesuai dengan tiga kota di Connecticut
3. Florida: Kode geografis 21142

Penargetan Kedekatan

Aturan kampanye yang menggunakan Matching Geo Targets dapat diterapkan ke lokasi yang ditargetkan, kedekatan yang ditargetkan, atau keduanya menggunakan flag TARGETING.

Penargetan lokasi cocok dengan kode geografis dengan ID lokasi.

Penargetan kedekatan memverifikasi bahwa koordinat lintang dan bujur yang ditentukan berada dalam radius proximity menggunakan formula Haversine.

Logika skrip

Skrip dimulai dengan membaca aturan dari ketiga lembar. Kemudian, sistem akan mencoba menjalankan setiap aturan dari sheet Kampanye secara berurutan.

Untuk setiap aturan yang dijalankan, skrip akan memeriksa apakah kampanye menargetkan lokasi yang ditentukan. Jika ya, skrip akan mengambil pengubah bid saat ini.

Selanjutnya, kondisi cuaca untuk lokasi tersebut diambil dengan melakukan panggilan ke OpenWeatherMap API. Aturan kondisi cuaca kemudian dievaluasi untuk melihat apakah kondisi cuaca untuk lokasi tersebut cocok dengan yang ditentukan dalam aturan. Jika ya, dan pengubah bid baru berbeda dari pengubah bid saat ini, skrip akan mengubah pengubah bid untuk lokasi tersebut.

Tidak ada perubahan yang dilakukan jika kondisi cuaca tidak cocok, jika nilai pengubah bid sama, atau jika Apply Modifier To dari aturan adalah Matching Geo Targets, tetapi kampanye tidak menargetkan lokasi yang dipetakan ke aturan.

Penyiapan

• Daftar untuk mendapatkan kunci API di openweathermap.org.
• Buat salinan spreadsheet template lalu edit aturan kampanye dan cuaca Anda.
• Buat skrip baru dengan kode sumber di bawah.
• Update variabel OPEN_WEATHER_MAP_API_KEY, SPREADSHEET_URL, dan TARGETING dalam skrip.
• Jadwalkan untuk dijalankan sesuai kebutuhan.
