4.2 Creazione di campagne pubblicitarie

Introduzione

---

Una volta completati correttamente i passaggi precedenti, puoi attivare la per creare campagne Performance Max per la vendita al dettaglio e usare imparare a prendere la decisione più intelligente per la pubblicazione di ogni annuncio.

Per capire che cosa devono fare gli inserzionisti manualmente nell'interfaccia utente di Google Ads per Per creare una campagna Performance Max, consulta l'articolo Creare una campagna Performance Max. Questa sezione descrive come utilizzare l'API Google Ads per attivare inserzionisti di creare campagne Performance Max per gli annunci Shopping.

Nota: se hai scelto l'opzione di reindirizzamento, non è richiesta l'integrazione dell'API per la creazione della campagna.

Solo le funzionalità di base della campagna che apportano il massimo valore al tuo i commercianti e minimizzando la complessità dell'implementazione sono trattati in questo . Per ogni campagna, ti consigliamo di fornire le seguenti tre opzioni di personalizzazione disponibili per i tuoi commercianti:

• Nome campagna: mostra come viene visualizzata la campagna nei report.

• Budget: l'importo che dovrebbe spendere in media per la campagna.

• Targeting geografico:punto in cui la campagna deve pubblicare gli annunci.

di Gemini Advanced.

Note sul targeting geografico:

• Questa funzionalità è consigliata, ma facoltativa nel caso in cui volessi ridurre ulteriormente la complessità dell'integrazione. Non è disponibile nell'opzione di reindirizzamento.
• Se questo campo viene omesso, i prodotti verranno pubblicati in tutti i paesi idonei. Se un prodotto non è idoneo alla pubblicazione in un determinato paese (ad es. non soddisfa i requisiti di spedizione), viene escluso automaticamente dalla campagna, senza che sia richiesta alcuna azione.

Inoltre, nel backend devi specificare alcuni altri parametri, elencati di seguito.

Strategia di offerta

La strategia di offerta automatica definisce ciò che massimizza la campagna quando imposta offerte. Per Performance Max sono disponibili due strategie di offerta:

• Massimizza le conversioni: la campagna cerca di massimizzare il numero di conversioni ottenute (ad es. il numero di acquisti) per il budget specificato.

• Massimizza il valore di conversione (opzione consigliata): la campagna cerca di massimizzare il valore monetario totale delle conversioni (ad esempio, dollari spesi su acquisti) per il budget specificato, come lo hai definito come parte della conversione impostazione del monitoraggio.

Per semplificare la complessità tecnica e l'esperienza dei commercianti, ti consigliamo di selezionare "Massimizza il valore di conversione" per conto tuo commercianti, senza ROAS target. È coerente con quanto disponibile tramite l'opzione di reindirizzamento.

Gruppi di asset e gruppi di schede

I gruppi di asset sono gli elementi in cui vengono archiviati gli elementi creativi della campagna, come prodotti, immagini, video. Sono fondamentali solo i prodotti del Gli argomenti trattati sono Merchant Center. Di conseguenza, ti serve un solo gruppo di asset per che potrai creare nel backend per conto del commerciante.

I gruppi di schede consentono ai commercianti di suddividere i prodotti di una campagna in gruppi (ad es. per pubblicizzare solo prodotti specifici). Questa è una funzionalità avanzata non consigliato come pilastro fondamentale, ma ogni campagna deve avere al almeno un gruppo di schede. Di conseguenza, ti serve un solo gruppo di schede per che potrai creare nel backend per conto del commerciante.

Nota: il gruppo di asset sostituisce quello che viene chiamato gruppo di annunci in altri tipi di campagna ad es. le campagne Shopping. Un gruppo di schede sostituisce il cosiddetto un gruppo di prodotti nelle campagne Shopping intelligenti.

Indicazioni per l'esperienza utente

---

La prima parte di questa sezione illustra lo scenario di creazione della prima campagna nell'ambito del flusso di onboarding di Google Ads. La seconda parte descrive modalità di creazione di altre campagne. Ciò è particolarmente pertinente se consentono ai commercianti di applicare il targeting geografico alle loro campagne.

Creazione di una campagna durante l'onboarding di Google Ads

Dopo aver collegato l'account Google Ads, all'utente viene chiesto di configurare Campagna Performance Max:

• Il nome della campagna può essere precompilato con un nome significativo, ad esempio Campagna Performance Max per il nome del tuo store builder.

• Consigliamo anche di includere un'anteprima del possibile aspetto di un annuncio e un breve spiegazione del funzionamento delle campagne Performance Max. L'API Google Ads non offre un modo per generare un'anteprima dell'annuncio, pertanto è necessario implementare uno tu. Non c'è bisogno di rendere il pixel perfetto, dato che il design tipo di annuncio potrebbe cambiare.

• Se il commerciante è idoneo a ricevere un coupon, questo deve essere indicato nel richiesta.

• Assicurati di fornire anche un link alle norme degli annunci Shopping in questo momento il flusso.

• Se vuoi, puoi consentire al commerciante di impostare la campagna come target geografico.

di Gemini Advanced.

Suggerimento: è meglio includere solo i paesi di destinazione disponibili nella feed dei prodotti di Merchant Center.

Quando il commerciante arriva alla fase di configurazione della campagna, i due scenari possono essere:

1. La fatturazione non è configurata. Questo vale sempre quando un nuovo account Google Ads è stato creato nell'ambito di questo flusso.

2. La fatturazione per l'account Google Ads collegato (ad esempio, il commerciante ha riutilizzato un account Google Ads che aveva già utilizzato per pubblicare altri tipi di campagne).

Gli scenari di fatturazione non funzionanti dovrebbero essere già stati rilevati in Google Ads per collegare l'account. L'unica differenza tra gli scenari 1 e 2 è comportamento e invito all'azione dell'azione principale:

• Per lo scenario 1, l'invito all'azione deve essere chiamato "Configura la fatturazione" e aprirai il riquadro di fatturazione pop-up. Una volta che hai fornito i dati di fatturazione e il popup è stato chiuso, procedi con Rivedi e completa la configurazione passaggio.

• Per lo scenario 2, l'invito all'azione dovrebbe essere chiamato "continua" e procedi direttamente Rivedi e completa la configurazione passaggio.

Di seguito è riportato un esempio di come potrebbe presentarsi il passaggio di configurazione della campagna per lo scenario 1.

Al commerciante devono essere fornite ulteriori informazioni sul nome della campagna, prodotti inclusi e il budget. Di seguito trovi un esempio.

Se il commerciante inserisce un budget inferiore alla soglia consigliata per il paese pubblica gli annunci, invia una notifica con un consiglio sul budget minimo. Di seguito puoi trovare un suggerimento in merito.

Dopo aver completato il passaggio di configurazione della campagna e fornito i dati di fatturazione (se necessario), l'utente passa alla fase di "revisione e completamento" passaggio. L'utente di rivedere la configurazione della campagna un'ultima volta prima lanciare la campagna. L'interfaccia utente potrebbe avere un aspetto simile al seguente in questo passaggio:

Dopo l'uscita dal flusso di onboarding, consigliamo di presentare un'anteprima all'utente su cosa succederà dopo. Di seguito è riportato un esempio.

Una volta uscito dall'onboarding, il commerciante deve essere indirizzato a una panoramica . Di seguito trovi un esempio.

Campagne display e creazione di altre campagne

L'interfaccia utente deve essere in grado di mostrare più campagne, come potrebbero aver fatto i commercianti campagne Performance Max esistenti o se vuoi crearne più di una soprattutto se consenti il targeting geografico. Esempio di come consentire a un commerciante di il targeting geografico delle campagne è mostrato di seguito. Assicurati sempre che il targeting geografico è più ristretto rispetto al paese o ai paesi in cui il commerciante fa pubblicità.

Quando un commerciante ha più di una campagna, aggrega le metriche pubblicitarie su la pagina Panoramica. Di seguito trovi un esempio.

Elenca le singole campagne nella visualizzazione dei dettagli di Google Ads. Un esempio di come questo guarda è di seguito.

La visualizzazione dei dettagli di Google Ads è anche il punto di partenza suggerito per la creazione campagne aggiuntive. Un esempio di come potrebbe essere questo flusso è mostrato in animazione qui sotto. Tieni presente che l'animazione salta l'inserimento delle informazioni sul budget come illustrato in precedenza.

Consulenza tecnica

---

Una volta collegato l'account Google Ads all'account Merchant Center, Per creare la campagna Performance Max per la vendita al dettaglio:

1. Crea operazione budget
2. Operazione di creazione campagna
3. Crea criteri per la campagna
4. Crea gruppo di asset con filtro del gruppo di schede
5. Esegui l'override degli obiettivi di conversione
6. Invia tutte le operazioni insieme

Tieni presente che quanto segue si applica per la gestione delle campagne Performance Max:

• Devi utilizzare almeno la versione 9 dell'API Google Ads

• Devi inviare tutte le operazioni di modifica in un'unica richiesta di modifica. Pertanto, devi prima creare tutte le operazioni di modifica e poi inviarle tutte insieme in una singola richiesta di modifica all'API Google Ads.

• Utilizzi ID temporanei in tutte le operazioni che crei perché invii una singola richiesta di modifica con tutte le operazioni, che le usano ID temporanei per comunicare a Google che sono tutti associati.

Nome insieme

Se è possibile che i tuoi commercianti accedano alla piattaforma Google Ads ti consigliamo di fare più attenzione al nome della campagna, è evidente che tu, in qualità di partner, hai creato la campagna in modo programmatico. Questo segnalerà al commerciante che è meglio apportare modifiche alla campagna all'interno della tua piattaforma e non quella di Google Ads. Ad esempio, anche se consentire al commerciante di personalizzare il nome, ti consigliamo di anteporre o aggiungere "Creata dalla piattaforma X".

Suggerimento: esegui dei controlli per ridurre il rischio dei concetti fondamentali di Merchant Center e Google Ads che le applicazioni presentino problemi di prestazioni. Ciò aiuta il commerciante a ottenere risultati ottimali. Vedi sezione 4.5 Gestione degli errori.

Passaggio 1. Crea l'operazione di budget

L'esempio di codice si trova in Creare un budget della campagna. In questo caso, evidenziare i punti più importanti:

• Una campagna Performance Max richiede un budget, come tutte le altre campagne, ma con le seguenti restrizioni:

  • Il budget deve avere un periodo di budget GIORNALIERO.
  • Il budget non può essere condiviso.

• Il metodo di pubblicazione per il budget è Standard. La consegna standard prende in considerazione il rendimento degli annunci previsto nell'arco della giornata ed è migliore nel massimizzarlo senza superare il budget giornaliero medio.

• Come accennato in precedenza in questa sezione, devi utilizzare gli ID temporanei tutte le operazioni che crei. Pertanto, nell'esempio di codice vedi che _BUDGET_TEMPORARY_ID è impostato nel nome della risorsa del budget, quindi può essere a cui la campagna fa riferimento nei passaggi successivi.

Passaggio 2: Creare la campagna e la strategia di offerta

Puoi fare riferimento all'esempio di codice Crea la campagna e la strategia di offerta per scoprire come definire uno standard Campagna Performance Max. Ecco alcune note aggiuntive:

• L'esempio di codice utilizza Massimizza il valore di conversione per la strategia di offerta. che è ciò che consigliamo di usare nel pilastro Fondazione. Con Massimizza Valore di conversione, hai la possibilità di specificare un ROAS target (ritorno Spesa pubblicitaria). Anche se scegli di non specificare un valore per il ROAS target, deve essere impostato, a meno che non utilizzi Java. In Java sono disponibili: setMaximizeConversionValue(MaximizeConversionValue.newBuilder().build())

• Per le versioni future, puoi utilizzare Massimizza le conversioni come un'altra opzione di strategia di offerta, con la possibilità di impostare un CPA target.

• L'espansione dell'URL consente alla campagna di avere come target l'intero dominio, non solo gli URL specificati nel Merchant Center dell'inserzionista. Ti consigliamo di Utilizzano l'espansione dell'URL finale, in modo che la copertura della campagna non sia limitata e il rendimento. Questo significa che gli annunci possono essere pubblicati per qualsiasi sul sito web del commerciante.

• start_date e end_date sono facoltativi.

Per una campagna Performance Max per la vendita al dettaglio, devi anche creare una ShoppingSetting con i seguenti campi e aggiungilo alla campagna. Questa opzione indica quale account Merchant Center vuoi utilizzare e quali che vuoi utilizzare nell'account. Come descritto nella sezione Crea una campagna Performance Max per la vendita al dettaglio, che devi impostare. ShoppingSetting campi:

• merchant_id (obbligatorio): l'ID Merchant Center dell'account che contiene i prodotti da pubblicizzare.

• feed_label (potrebbe essere obbligatorio): se esiste la possibilità che tu abbia un commerciante utilizzando un account Merchant Center esistente con i vecchi feed dei prodotti, deve utilizzare feed_label per specificare che la campagna utilizzi il prodotto il feed che hai creato; questo viene mappato a DatafeedTarget nell'API Content.

Ecco un esempio dell'operazione per creare una campagna Performance Max per la vendita al dettaglio campagna e strategia di offerta. Questo presuppone che ci siano un feed dei prodotti nell'account Merchant Center (quello che gestisci), quindi non imposta 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

Passaggio 3: Creare i criteri della campagna

Puoi vedere l'esempio di codice in Creare i criteri della campagna, quindi qui sono i punti più importanti:

• Come illustrato nell'esempio di codice, devi prima avviare tutti i servizi necessari prima di procedere con la configurazione dei criteri della campagna LOCATION e LANGUAGE.

• Quando imposti i criteri della campagna LOCATION, puoi aggiungere target da escludere per località da escludere impostando campaign_criterion.negative su Vero.

• Assicurati di utilizzare lo stesso ID temporaneo del passaggio 2 per indicare a Google quale campagna che sta creando questo criterio.

Passaggio 4: Creare il gruppo di asset con il filtro del gruppo di schede

Come descritto in Creare gruppi di asset Performance Max, un gruppo di asset viene una raccolta di asset incentrata su un tema o correlata a un pubblico di destinazione. La gruppo di asset viene utilizzato per assemblare tutti gli annunci e creare un inventario per tutti formati dell'annuncio adatti al tuo obiettivo pubblicitario.

Puoi utilizzare i gruppi di schede Shopping per suddividere i prodotti in gruppi, includere un insieme di prodotti o escluderli. Ti permette di filtrare l'insieme prodotti idonei a essere visualizzati nella campagna.

Puoi visualizzare l'esempio di codice per creare più gruppi di schede di prodotto in gruppi di schede Performance Max, ma come pilastro della base è di configurare un'unica campagna che abbia come target tutte le prodotti di big data e machine learning. Di seguito è riportato un esempio di codice più semplice. Devi includere un parametro nodo principale AssetGroupListingGroupFilter contenente tutti i prodotti. Altrimenti, gli annunci non vengono pubblicati.

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

Puoi aggiungere titoli, descrizioni e persino immagini al gruppo di asset per migliorare il rendimento delle campagne. Tuttavia, poiché questo non è un requisito per Performance Max per la vendita al dettaglio, lo sconsigliato per le funzionalità di base.

Passaggio 5: Sovrascrivi gli obiettivi di conversione

Come indicato nella sezione Monitoraggio delle conversioni, se consenti ai commercianti di utilizzare un account Google Ads esistente, ti consigliamo vivamente di imposti gli obiettivi di conversione a livello di campagna. Per farlo, basta eseguire l'override gli obiettivi di conversione a livello di cliente o di account. Se non a livello di campagna l'obiettivo di conversione è impostato, per impostazione predefinita la campagna utilizza la conversione a livello di cliente obiettivo.

Un esempio di codice è disponibile in Aggiornamento degli obiettivi di conversione della campagna. Per prima cosa, devi ottenere gli obiettivi di conversione dell'account. Puoi quindi ripetere obiettivi di conversione e verificare se ogni obiettivo è incrementare le vendite online, ovvero categoria PURCHASE, SITE di origine). In caso contrario, imposta l'offerta su False. Se imposta l'offerta su True. In questo modo, la campagna Performance Max è ottimizzato per aumentare le vendite online.

Passaggio 6: Invia tutte le operazioni di modifica insieme

Infine, devi inviare tutte le operazioni di modifica insieme. Come mostrato nel codice esempio qui sotto, l'ordine delle operazioni è importante, in quanto dipendono e l'altro. Ad esempio, performance_max_campaign_operation utilizza i dati di campaign_budget_operation e campaign_criterion_operations utilizzano i dati di 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
   ],
)

Dopo aver creato correttamente la campagna, l'API restituisce un risultato simile al seguente:

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"
}
}

Salva il resource_name della campagna e del budget perché ne hai bisogno quando la modifica delle impostazioni della campagna e per la generazione di report.

Riassumendo: Puoi trovare esempi di codice completi per la creazione di una campagna Performance Max per la vendita al dettaglio nella sezione Esempi di codice della documentazione dell'API Google Ads. Tieni presente che questi esempi potrebbero includere istruzioni per implementare funzionalità aggiuntive rispetto a quelle consigliate nel pilastro di base, tra cui l'aggiunta di ulteriori asset titolo e immagine.

 *
 * 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

"""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 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.
