입찰가 설정 또는 업데이트

Google Ads API를 사용하여 호텔 광고에 대한 입찰가를 설정하거나 업데이트할 수 있습니다.

참고: 0이 아닌 모든 입찰가 (입찰가 조정 포함)는 숙박 시설 프로모션 광고를 게재할 수 있습니다 (AdGroup.type = PROMOTED_HOTEL_ADS일 경우).

bidding_strategy 또는 bidding_strategy_type 필드를 설정하지 마세요. bidding_strategy_type 필드는 캠페인의 현재 설정을 읽기 위한 전용이며 읽기 전용입니다.

수수료 (전환당 또는 숙박당) 전략의 경우:

• 처음에는 입찰 전략을 할당하는 과정에서 캠페인 수준에서 입찰가를 설정합니다.
• 전략을 할당할 때 캠페인 수준에서 설정된 전환 가치의 고정된 비율을 업데이트하여 입찰가를 업데이트할 수 있습니다. 자세한 내용은 입찰 전략 업데이트를 참고하세요.

CPC 비율 또는 수동 CPC 전략의 경우:

• 광고그룹 수준에서 입찰가를 설정하거나 업데이트할 수 있습니다. 자세한 내용은 CPC 비율 또는 수동 CPC 입찰가 설정을 참조하세요.
• 캠페인 수준에서 향상된 CPC 입찰기능을 사용하도록 입찰을 업데이트할 수 있습니다. 향상된 CPC 입찰기능에 대해 자세히 알아보려면 호텔 광고에 적용할 수 있는 향상된 CPC 입찰기능 정보를 참고하세요. 향상된 CPC 입찰기능을 사용하도록 입찰을 업데이트하려면 입찰 전략 지정을 참조하세요.

CPC 비율 또는 수동 CPC 입찰가 설정

CPC 비율 및 수동 CPC 입찰 전략의 경우 특정 입찰가를 다음 값으로 설정해야 합니다.

• 광고그룹 수준
• 등록정보 그룹 트리의 단위 노드의 등록정보 그룹 수준

이 값은 광고그룹 수준에서 설정해야 하지만 호텔 광고에서는 사용되지 않습니다. 호텔 광고는 등록정보 그룹 수준의 값을 사용하며 이 값이 광고그룹 수준의 관련 없는 값을 재정의합니다.

입찰 전략을 설정하는 과정에서 캠페인 수준에서 입찰가 상한을 관리할 수도 있습니다. 자세한 내용은 입찰 전략 할당 또는 업데이트를 참고하세요.

등록정보 그룹 단위 노드에 입찰가 설정

호텔 등록정보 그룹 만들기에 설명된 대로 호텔 광고는 하나 이상의 객실 노드가 포함된 유효한 등록정보 그룹 트리를 만들 때까지 게재되지 않습니다. 또한 노드는 ListingGroupInfo 클래스의 객체이며, 여기에는 노드가 단위인지 하위 그룹인지 나타내는 ListingGroupType 필드가 포함되어 있습니다. ListingGroupInfo를 AdGroupCriterion의 listing_group로 설정하면 ListingGroupInfo 객체가 AdGroup에 연결됩니다. AdGroupCriterion의 percent_cpc_bid_micros 필드 또는 cpc_bid_micros 필드를 설정하여 단위 노드에 입찰을 설정할 수 있습니다. 하위 그룹에서 이를 수행하려고 하면 오류가 발생하고 실패합니다.

등록정보 그룹 수준에서 입찰가를 설정할 때는 다음 사항에 유의하세요.

• '모든 호텔' (루트) 호텔 등록정보 그룹에는 입찰가를 설정할 수 없습니다.
• 하위 그룹에는 입찰가를 설정할 수 없습니다.
• 단위 노드인 '기타' 노드에 입찰가를 설정하지 않는 것이 좋습니다. '기타' (단위) 노드에 대한 입찰가는 다른 호텔 광고 입찰가에 의도하지 않은 영향을 미칠 수 있습니다.

아래 코드는 등록정보 그룹 단위 노드에 입찰가를 설정하는 방법을 보여줍니다.
