4.2 Pembuatan Kampanye Google Ads

Pengantar

---

Setelah berhasil menyelesaikan langkah-langkah sebelumnya, Anda dapat mengaktifkan penjual untuk membuat kampanye Performa Maksimal Retail dan menggunakan mesin untuk membuat keputusan yang paling tepat guna menayangkan setiap iklan.

Untuk memahami apa yang harus dilakukan pengiklan secara manual di UI Google Ads untuk membuat kampanye Performa Maksimal, lihat Membuat kampanye Performa Maksimal. Bagian ini menjelaskan cara menggunakan Google Ads API untuk mengaktifkan pengiklan untuk membuat kampanye Performa Maksimal yang menayangkan Iklan Shopping.

Catatan: jika Anda memilih opsi pengalihan, integrasi API tidak diperlukan untuk pembuatan kampanye.

Hanya fungsi kampanye dasar yang memberikan manfaat maksimal bagi penjual sekaligus meminimalkan kompleksitas implementasi bagian. Untuk setiap kampanye, sebaiknya sediakan tiga hal berikut opsi penyesuaian untuk penjual Anda:

• Nama kampanye: Cara kampanye ditampilkan dalam pelaporan.

• Anggaran: Jumlah yang harus dibelanjakan kampanye rata-rata.

• Penargetan geografis: Tempat kampanye akan menayangkan iklan.

Catatan Penargetan Geografis:

• Fungsi ini direkomendasikan tetapi bersifat opsional jika Anda ingin lebih mengurangi kompleksitas integrasi. Tidak tersedia pada opsi pengalihan.
• Jika kolom ini dihilangkan, produk akan ditayangkan di semua negara yang memenuhi syarat. Jika produk tidak memenuhi syarat untuk ditayangkan di negara tertentu (misalnya, tidak memenuhi Persyaratan pengiriman), produk tersebut akan otomatis dikecualikan dari kampanye, tanpa perlu tindakan apa pun.

Selain itu, di backend Anda perlu menentukan beberapa parameter lagi, yang tercantum di bawah ini.

Strategi bidding

Strategi bidding otomatis menentukan apa yang dimaksimalkan kampanye saat menetapkan maksimum. Untuk Performa Maksimal, tersedia dua strategi bidding:

• Maksimalkan konversi: kampanye mencoba memaksimalkan jumlah konversi yang dicapai (misalnya, jumlah pembelian) untuk anggaran yang ditentukan.

• Maksimalkan nilai konversi (direkomendasikan): kampanye mencoba memaksimalkan total nilai uang konversi (misalnya, dolar yang dibelanjakan untuk pembelian) untuk anggaran yang diberikan, seperti yang Anda tetapkan sebagai bagian dari konversi. pengaturan pelacakan.

Untuk menyederhanakan kerumitan teknis dan pengalaman bagi penjual, kami sebaiknya pilih "Maksimalkan nilai konversi" atas nama penjual, tanpa target ROAS. Hal ini sesuai dengan yang tersedia melalui opsi pengalihan.

Grup aset dan grup listingan

Grup aset adalah tempat penyimpanan elemen materi iklan dari kampanye. seperti produk, gambar, video. Pada pilar dasar, hanya produk dari Merchant Center. Oleh karena itu, Anda hanya memerlukan satu grup aset per kampanye, yang dapat dibuat di backend atas nama penjual.

Grup listingan memungkinkan penjual membagi produk dalam kampanye ke dalam grup (misalnya, untuk hanya mengiklankan produk tertentu). Ini adalah fitur lanjutan tidak direkomendasikan sebagai pilar dasar, tetapi setiap kampanye harus memiliki setidaknya satu grup listingan. Oleh karena itu, Anda hanya memerlukan satu grup listingan per kampanye, yang dapat dibuat di backend atas nama penjual.

Catatan: Grup Aset menggantikan Grup Iklan di jenis kampanye lain (misalnya, kampanye Shopping). Dan Grup Listingan menggantikan apa yang disebut Grup Produk dalam Kampanye Shopping Pintar.

Panduan UX

---

Bagian pertama dari bagian ini membahas skenario pembuatan sebagai bagian dari alur aktivasi Google Ads. Bagian kedua menjelaskan cara membuat kampanye tambahan. Hal ini sangat relevan jika Anda memungkinkan penjual untuk menargetkan kampanye mereka secara geografis.

Pembuatan kampanye selama aktivasi Google Ads

Setelah menghubungkan akun Google Ads, pengguna diminta untuk menyiapkan Kampanye Performa Maksimal:

• Nama kampanye dapat diisi otomatis dengan nama yang bermakna, misalnya, Kampanye Performa Maksimal untuk nama pembuat toko Anda.

• Sebaiknya Anda juga menyertakan pratinjau tampilan iklan dan penjelasan singkat tentang cara kerja kampanye Performa Maksimal. Google Ads API tidak menawarkan cara untuk menghasilkan pratinjau iklan, jadi Anda harus menerapkannya satu per satu. Tidak perlu membuatnya sempurna hingga {i>pixel<i}, karena desain jenis iklan mungkin berubah.

• Jika penjual memenuhi syarat untuk mendapatkan kupon, kupon tersebut harus disebutkan di .

• Pastikan juga untuk menyediakan link ke kebijakan Iklan Shopping pada tahap ini dengan aliran data.

• Selain itu, Anda dapat mengizinkan penjual untuk menargetkan kampanye secara geografis.

Tips: Sebaiknya hanya sertakan negara target yang tersedia di kolom Feed produk Merchant Center.

Dua skenario dapat terjadi saat penjual tiba di langkah penyiapan kampanye:

1. Penagihan belum disiapkan. Hal ini selalu terjadi jika akun Google Ads baru telah dibuat sebagai bagian dari alur ini.

2. Penagihan sudah disiapkan untuk akun Google Ads yang terhubung (misalnya, penjual menggunakan kembali akun Google Ads yang sudah mereka gunakan untuk menjalankan jenis kampanye lainnya).

Skenario penagihan bermasalah seharusnya sudah ada di Google Ads langkah penautan akun. Perbedaan antara skenario 1 dan 2 adalah perilaku dan pesan ajakan (CTA) dari tindakan utama:

• Untuk Skenario 1, CTA harus disebut 'siapkan penagihan' dan buka penagihan di jendela pop-up. Setelah penagihan diberikan dan jendela pop-up ditutup, lanjutkan ke 'tinjau dan selesaikan penyiapan' langkah waktu ini.

• Untuk skenario 2, CTA harus disebut 'lanjutkan' dan langsung melanjutkan ke 'tinjau dan selesaikan penyiapan' langkah waktu ini.

Berikut contoh tampilan langkah penyiapan kampanye untuk skenario 1.

Informasi tambahan harus diberikan kepada penjual terkait nama kampanye. termasuk produk dan anggarannya. Berikut contoh tampilannya.

Jika penjual memasukkan anggaran di bawah nilai minimum yang direkomendasikan untuk negara yang bersangkutan tempat mereka beriklan, memberikan notifikasi dengan rekomendasi anggaran minimum. Berikut saran tampilannya.

Setelah menyelesaikan langkah penyiapan kampanye dan memberikan informasi penagihan (jika perlu), pengguna melanjutkan ke "tinjauan dan selesai" langkah waktu ini. Pengguna diberikan kesempatan untuk meninjau penyiapan kampanye untuk terakhir kalinya sebelum meluncurkan kampanye. UI mungkin terlihat seperti ini di langkah ini:

Setelah keluar dari alur orientasi, sebaiknya tampilkan pratinjau kepada pengguna tentang apa yang akan terjadi selanjutnya. Contohnya ditampilkan di bawah ini.

Setelah keluar dari aktivasi, penjual akan diarahkan ke ringkasan kami. Berikut contoh tampilannya.

Kampanye Display dan membuat kampanye tambahan

UI Anda harus dapat menampilkan beberapa kampanye, karena penjual mungkin memiliki kampanye Performa Maksimal yang ada atau ingin membuat lebih dari satu kampanye, terutama jika Anda mengizinkan mereka melakukan penargetan geografis. Contoh yang memungkinkan penjual untuk menargetkan kampanye mereka secara geografis ditampilkan di bawah ini. Selalu pastikan bahwa penargetan geografis lebih sempit dari negara atau beberapa negara tempat penjual beriklan.

Jika penjual memiliki lebih dari satu kampanye, gabungkan metrik iklan dalam ke halaman ringkasan. Berikut contoh tampilannya.

Cantumkan masing-masing kampanye di tampilan detail Google Ads. Contoh yang menunjukkan mungkin terlihat di bawah ini.

Tampilan detail Google Ads juga merupakan titik awal yang disarankan untuk membuat kampanye tambahan. Contoh tampilan alur ini ditunjukkan dalam animasi di bawah ini. Perhatikan bahwa animasi akan dilewati saat mengisi informasi anggaran seperti yang dibahas sebelumnya dalam panduan ini.

Panduan Teknologi

---

Setelah akun Google Ads ditautkan ke akun Merchant Center, Anda dapat membuat kampanye Performa Maksimal untuk Retail menggunakan langkah-langkah berikut:

1. Buat operasi anggaran
2. Buat operasi kampanye
3. Buat kriteria kampanye
4. Buat grup aset dengan filter grup listingan
5. Ganti sasaran konversi
6. Mengirim semua operasi sekaligus

Perhatikan bahwa hal berikut berlaku untuk mengelola kampanye Performa Maksimal:

• Anda harus menggunakan setidaknya versi 9 Google Ads API

• Anda harus mengirim semua operasi mutasi dalam satu permintaan mutasi tunggal. Oleh karena itu, Anda harus membuat semua operasi mutasi terlebih dahulu, lalu mengirimkannya bersama-sama dalam satu permintaan mutasi ke Google Ads API.

• Anda menggunakan ID sementara pada semua operasi yang dibuat karena Anda mengirim satu permintaan mutasi dengan semua operasi, dan operasi itu menggunakan ID sementara untuk memberi tahu Google bahwa mereka semua adalah satu.

Nama kumpulan

Jika ada kemungkinan penjual Anda mengakses platform Google Ads langsung, Anda mungkin harus lebih mempertimbangkan nama kampanye sehingga sudah jelas bahwa Anda, sebagai partner, membuat kampanye secara terprogram. Ini akan memberi tahu penjual bahwa sebaiknya mengedit kampanye dari dalam platform Anda, bukan di platform Google Ads. Misalnya, meskipun Anda izinkan penjual untuk menyesuaikan nama, Anda dapat menambahkan awalan atau "Dibuat oleh platform X".

Tips: Lakukan pemeriksaan untuk mengurangi risiko dasar dari Merchant Center dan Ads masalah performa. Hal ini membantu menyiapkan penjual untuk meraih kesuksesan. Lihat bagian 4.5 Penanganan Error.

Langkah 1. Membuat operasi anggaran

Contoh kode dapat ditemukan di artikel Membuat anggaran kampanye, jadi di sini kita hanya menyoroti hal-hal yang paling penting:

• Kampanye Performa Maksimal memerlukan anggaran, seperti semua kampanye lainnya, tetapi dengan batasan berikut:

  • Anggaran harus memiliki periode anggaran HARIAN.
  • Anggaran tidak dapat dibagikan.

• Metode penayangan untuk anggaran adalah Standar. Penayangan standar memperhitungkan akun untuk performa iklan yang diharapkan sepanjang hari dan lebih baik dalam memaksimalkan performa sesuai dengan anggaran harian rata-rata Anda.

• Seperti yang disebutkan sebelumnya di bagian ini, Anda perlu menggunakan ID sementara di semua operasi yang Anda buat. Oleh karena itu, Anda melihat dalam contoh kode bahwa _BUDGET_TEMPORARY_ID ditetapkan dalam nama resource anggaran sehingga dapat oleh kampanye di langkah-langkah berikutnya.

Langkah 2. Membuat kampanye dan strategi bidding

Anda dapat melihat contoh kode di Buat kampanye dan strategi bidding untuk mempelajari cara membuat bidding standar Kampanye Performa Maksimal. Berikut beberapa catatan tambahan:

• Contoh kode ini menggunakan Maksimalkan Nilai Konversi untuk strategi bidding, yang kami rekomendasikan untuk Anda gunakan di pilar Fondasi. Dengan Maksimalkan Nilai Konversi, Anda memiliki opsi untuk menentukan target ROAS (Laba atas Pembelanjaan Iklan). Meskipun memilih untuk tidak menentukan nilai target ROAS, Anda harus menyetelnya, kecuali jika Anda menggunakan Java. Di Java, Anda memiliki: setMaximizeConversionValue(MaximizeConversionValue.newBuilder().build())

• Untuk versi mendatang, Anda dapat mempertimbangkan untuk menggunakan Maksimalkan Konversi sebagai opsi strategi bidding lainnya, dengan kemampuan untuk menetapkan target CPA.

• Perluasan URL memungkinkan kampanye menarget seluruh domain, bukan hanya URL yang ditentukan di Merchant Center pengiklan. Sebaiknya Anda gunakan perluasan URL final, sehingga jangkauan kampanye tidak terbatas dan dan pada akhirnya. Perhatikan bahwa ini berarti iklan dapat ditayangkan kepada di situs penjual.

• start_date dan end_date bersifat opsional.

Untuk kampanye Performa Maksimal untuk Retail, Anda juga harus membuat ShoppingSetting dengan kolom berikut, lalu tambahkan ke kampanye. Bagian ini menentukan akun Merchant Center yang ingin Anda gunakan, beserta feed produk yang ingin digunakan di akun tersebut. Seperti yang dijelaskan dalam Membuat kampanye retail Performa Maksimal, Anda harus menetapkannya Kolom ShoppingSetting:

• merchant_id (wajib): ID Merchant Center untuk akun yang berisi produk yang akan diiklankan.

• feed_label (mungkin wajib): jika ada kemungkinan Anda memiliki menggunakan akun Merchant Center yang ada dengan feed produk lama, Anda harus menggunakan feed_label untuk menentukan bahwa Anda ingin kampanye menggunakan produk tersebut feed yang telah dibuat; dipetakan ke DatafeedTarget di Content API.

Berikut contoh operasi untuk membuat Performa Maksimal untuk Retail kampanye dan strategi bidding Anda. Hal ini mengasumsikan bahwa hanya ada satu feed produk di akun Merchant Center (yaitu, yang Anda kelola), jadi ini tidak menetapkan feed_label.

Python
mutate_operation = googleads_client.get_type("MutateOperation")
campaign = mutate_operation.campaign_operation.create
campaign.name = f"Performance Max campaign #{uuid4()}"

campaign.status = googleads_client.enums.CampaignStatusEnum.ENABLED

campaign.advertising_channel_type = (       googleads_client.enums.AdvertisingChannelTypeEnum.PERFORMANCE_MAX
)

# Add Merchant Center ID to create a Performance Max for Retail
# campaign. This ID should be linked to the Ads account
# where you are creating the campaign
campaign.shopping_setting.merchant_id = int(google_merchant_id)
campaign.maximize_conversion_value.target_roas = None

# Set the Final URL expansion opt out. This option is specific to
# Performance Max campaigns. If opted out (True), only the
# final URLs in the asset group or URLs specified in the
# advertiser's Google Merchant Center or business data feeds are
# targeted.
# If opted in (False), the entire domain will be targeted.
# For best results, set this value to false to opt in and allow
# URL expansions. You can optionally add exclusions to limit
# traffic to parts of your website.
campaign.url_expansion_opt_out = False

# Assign the resource name with a temporary ID.
campaign_service = googleads_client.get_service("CampaignService")
campaign.resource_name = campaign_service.campaign_path(
       customer_id, _PERFORMANCE_MAX_CAMPAIGN_TEMPORARY_ID
)

# Set the budget using the given budget resource name.
campaign.campaign_budget = campaign_service.campaign_budget_path(
      customer_id, _BUDGET_TEMPORARY_ID
)

print("mutate_operation for step 2 - campaign and bidding strategy creation")
print(mutate_operation)

return mutate_operation

Langkah 3. Membuat kriteria kampanye

Anda dapat melihat contoh kode di bagian Membuat kriteria kampanye, jadi berikut adalah poin terpenting:

• Seperti yang ditunjukkan contoh kode, Anda harus terlebih dahulu memulai semua layanan yang diperlukan sebelum melanjutkan untuk mengonfigurasi kriteria kampanye LOCATION dan LANGUAGE.

• Saat menetapkan kriteria kampanye LOCATION, Anda dapat menambahkan target negatif untuk lokasi yang ingin Anda kecualikan dengan menyiapkan campaign_criterion.negative untuk Benar.

• Pastikan untuk menggunakan ID sementara yang sama dari langkah 2 untuk memberi tahu Google mengenai kampanye tempat Anda membuat kriteria ini.

Langkah 4. Membuat grup aset dengan filter grup listingan

Seperti yang dijelaskan dalam Membuat Grup Aset Performa Maksimal, grup aset bersifat sekumpulan aset yang berpusat pada tema atau terkait dengan target audiens. Tujuan grup aset digunakan untuk menyusun semua iklan dan membuat inventaris untuk semua format iklan yang relevan untuk tujuan iklan Anda.

Anda dapat menggunakan Grup listingan Shopping untuk membagi produk ke dalam grup untuk menyertakan satu set produk atau mengecualikannya. Hal ini memungkinkan Anda memfilter kumpulan produk yang valid untuk ditampilkan dalam kampanye.

Anda dapat melihat contoh kode untuk membuat beberapa grup listingan produk di Grup listingan Performa Maksimal, tetapi untuk pilar Dasar, hal ini sebaiknya Anda menyiapkan satu kampanye yang menargetkan semua Google. Oleh karena itu, contoh kode yang lebih sederhana disertakan di bawah. Anda harus menyertakan node root AssetGroupListingGroupFilter yang berisi semua produk. Jika tidak, iklan tidak ditayangkan.

Python
googleads_service = googleads_client.get_service("GoogleAdsService")

operations = []

# Create the AssetGroup
mutate_operation = googleads_client.get_type("MutateOperation")
asset_group = mutate_operation.asset_group_operation.create
asset_group.name = f"Performance Max asset group #{uuid4()}"
asset_group.campaign = googleads_service.campaign_path(
       customer_id, _PERFORMANCE_MAX_CAMPAIGN_TEMPORARY_ID
)

asset_group.status = googleads_client.enums.AssetGroupStatusEnum.ENABLED
asset_group.resource_name = googleads_service.asset_group_path(
      customer_id,
      _ASSET_GROUP_TEMPORARY_ID,
)
operations.append(mutate_operation)

# Create a listing group and link it to the AssetGroup.
# The way you link a listing group to an AssetGroup is different
# than when you are linking headlines, descriptions, images, etc
# where you set the field_type of the asset_group_asset as HEADLINE, for example.
# https://developers.google.com/google-ads/api/reference/rpc/v13/AssetGroupListingGroupFilter
mutate_operation = googleads_client.get_type("MutateOperation")
asset_group_listing_group = mutate_operation.asset_group_listing_group_filter_operation.create
asset_group_listing_group.asset_group = googleads_service.asset_group_path(
       customer_id,
       _ASSET_GROUP_TEMPORARY_ID,
)

asset_group_listing_group.type_ = googleads_client.enums.ListingGroupFilterTypeEnum.UNIT_INCLUDED
# here are other options for ListingGroupFilterTypeEnum
# https://developers.google.com/google-ads/api/reference/rpc/v13/ListingGroupFilterTypeEnum.ListingGroupFilterType

asset_group_listing_group.vertical = googleads_client.enums.ListingGroupFilterVerticalEnum.SHOPPING

operations.append(mutate_operation)

print("mutate_operation for step 4 - create asset group and product group attached to that asset group")
print(operations)

return operations

Anda dapat menambahkan judul, deskripsi, dan bahkan gambar ke grup aset untuk meningkatkan performa kampanye. Namun, karena ini bukan persyaratan untuk Performa Maksimal untuk Retail, kami tidak merekomendasikannya untuk pilar Dasar.

Langkah 5. Timpa sasaran konversi

Seperti yang dinyatakan di bagian Tracking Konversi, jika Anda mengizinkan penjual sebaiknya menggunakan akun Google Ads yang ada, sebaiknya Anda dapat menetapkan sasaran konversi di tingkat kampanye. Hal ini dapat dilakukan dengan mengganti sasaran konversi di tingkat pelanggan atau akun. Saat tidak ada tingkat kampanye sasaran konversi ditetapkan, kampanye secara default akan ditetapkan ke konversi tingkat pelanggan sasaran.

Contoh kode dapat ditemukan di Memperbarui Sasaran Konversi Kampanye. Pertama, Anda harus mendapatkan sasaran konversi akun. Anda kemudian dapat melakukan iterasi melalui sasaran konversi dan memeriksa apakah setiap sasaran ditujukan untuk mendorong penjualan online (yaitu, kategori PEMBELIAN, SITUS WEB asal). Jika tidak, tetapkan kemampuan bid ke Salah (False). Jika yang sama, tetapkan kemampuan di-bid ke True (Benar). Dengan begitu, kampanye Performa Maksimal dioptimalkan untuk meningkatkan penjualan online.

Langkah 6. Mengirim semua operasi mutasi secara bersamaan

Terakhir, Anda harus mengirim semua operasi mutasi sekaligus. Seperti yang ditunjukkan dalam kode di bawah ini, urutan operasi itu penting, karena mereka bergantung pada lainnya. Misalnya, performance_max_campaign_operation menggunakan data dari campaign_budget_operation, dan campaign_criterion_operations menggunakan data dari performance_max_campaign_operation.

Python
ga_service = googleads_client.get_service("GoogleAdsService")
response = ga_service.mutate(
   customer_id=customer_id,
   mutate_operations=[
       # It's important to create the entities in this order
       # because they depend on each other
       campaign_budget_operation,       # Step 1
       performance_max_campaign_operation,  # Step 2
       # Expand the list of multiple operations into the list of
       # other mutate operations
       *campaign_criterion_operations,  # Step 3
       *asset_group_operations,             # Step 4
       *conversion_goal_operations,         # Step 5
   ],
)

Setelah kampanye berhasil dibuat, API akan menampilkan hal seperti ini:

Python
mutate_operation_responses {
campaign_budget_result {
resource_name: "customers/7244690427/campaignBudgets/10689184019"
}
}
mutate_operation_responses {
campaign_result {
    resource_name: "customers/7244690427/campaigns/16822128600"
}
}
mutate_operation_responses {
campaign_criterion_result {
        resource_name: "customers/7244690427/campaignCriteria/16822128600~20009"
}
}
mutate_operation_responses {
    campaign_criterion_result {
resource_name: "customers/7244690427/campaignCriteria/16822128600~20024"
    }
}
mutate_operation_responses {
campaign_criterion_result {
        resource_name: "customers/7244690427/campaignCriteria/16822128600~1003"
    }
}
mutate_operation_responses {
asset_group_result {
        resource_name: "customers/7244690427/assetGroups/6444254998"
    }
}
mutate_operation_responses {
asset_group_listing_group_filter_result {
    resource_name: "customers/7244690427/assetGroupListingGroupFilters/6444254998~6454725458"
}
}
mutate_operation_responses {
campaign_conversion_goal_result {
    resource_name: "customers/7244690427/campaignConversionGoals/16822128600~PURCHASE~WEBSITE"
}
}

Simpan resource_name kampanye dan anggaran karena Anda memerlukannya saat mengedit setelan kampanye dan untuk tujuan pelaporan.

Menyatukan semuanya: Anda dapat menemukan contoh kode komprehensif terkait pembuatan kampanye Performa Maksimal untuk Retail di bagian Contoh Kode dalam dokumentasi Ads API. Perhatikan bahwa contoh ini dapat menyertakan petunjuk untuk menerapkan fitur selain yang direkomendasikan dalam pilar Dasar, termasuk menambahkan judul dan aset gambar tambahan.

/**
 * This example shows how to create a Performance Max retail campaign.
 *
 * This will be created for "All products".
 *
 * For more information about Performance Max retail campaigns, see
 * https://developers.google.com/google-ads/api/docs/performance-max/retail.
 *
 * Prerequisites:
 * - You need to have access to a Merchant Center account. You can find
 * instructions to create a Merchant Center account here:
 * https://support.google.com/merchants/answer/188924.
 * This account must be linked to your Google Ads account. The integration
 * instructions can be found at:
 * https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
 * - You need your Google Ads account to track conversions. The different ways
 * to track conversions can be found here:
 * https://support.google.com/google-ads/answer/1722054.
 * - You must have at least one conversion action in the account. For more about conversion
 * actions, see
 * https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions.

"""This example shows how to create a Performance Max retail campaign.

This will be created for "All products".

For more information about Performance Max retail campaigns, see
https://developers.google.com/google-ads/api/docs/performance-max/retail

Prerequisites:
- You need to have access to a Merchant Center account. You can find
  instructions to create a Merchant Center account here:
  https://support.google.com/merchants/answer/188924.
  This account must be linked to your Google Ads account. The integration
  instructions can be found at:
  https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
- You need your Google Ads account to track conversions. The different ways
  to track conversions can be found here:
  https://support.google.com/google-ads/answer/1722054.
- You must have at least one conversion action in the account. For
  more about conversion actions, see
  https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions

#
# For more information about Performance Max retail campaigns, see
# https://developers.google.com/google-ads/api/docs/performance-max/retail
#
# Prerequisites:
# - You need to have access to a Merchant Center account. You can find
#   instructions to create a Merchant Center account here:
#   https://support.google.com/merchants/answer/188924.
#   This account must be linked to your Google Ads account. The integration
#   instructions can be found at:
#   https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center
# - You need your Google Ads account to track conversions. The different ways
#   to track conversions can be found here:
#   https://support.google.com/google-ads/answer/1722054.
# - You must have at least one conversion action in the account. For
#   more about conversion actions, see
#   https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions

#
# This will be created for "All products".
#
# For more information about Performance Max retail campaigns, see
# https://developers.google.com/google-ads/api/docs/performance-max/retail.
#
# Prerequisites:
# - You need to have access to a Merchant Center account. You can find
#   instructions to create a Merchant Center account here:
#   https://support.google.com/merchants/answer/188924.
#   This account must be linked to your Google Ads account. The integration
#   instructions can be found at:
#   https://developers.google.com/google-ads/api/docs/shopping-ads/merchant-center.
# - You need your Google Ads account to track conversions. The different ways
#   to track conversions can be found here:
#   https://support.google.com/google-ads/answer/1722054.
# - You must have at least one conversion action in the account. For more about
#   conversion actions, see
#   https://developers.google.com/google-ads/api/docs/conversions/overview#conversion_actions.

Status kampanye berjalan: Agar kampanye dapat berjalan, setidaknya satu produk harus disetujui di Merchant Center. Jika tidak, status kampanye menunjukkan bahwa kampanye berjalan padahal sebenarnya tidak.

Pemecahan masalah: Login ke platform Google Ads sebagai akun pengelola. Buka kampanye Performa Maksimal sub-akun dan periksa setelan kampanye. Ada baiknya juga jika Anda melihat histori perubahan untuk mengonfirmasi bahwa Andalah yang melakukan perubahan menggunakan Ads API.
