設定服務順序

重點提示：如未按照這項設定操作，系統就會按任意順序顯示服務。

規格

如要影響特定商家服務的顯示順序，請在服務動態饋給中的每個 Service 上設定 ranking_hint.score。

// Ranking hints for a service.
message ServiceRankingHint {
  // Arbitrary partner or merchant assigned rank for this service.
  //
  // Services with a higher score will be shown more prominently (e.g. shown
  // higher in lists). Note that other factors may also influence ranking, such
  // as price, availability, user history, etc.
  //
  // Optional. Must be non-negative if set.
  optional float score = 1;
}

顯示多項服務時 (例如，「預訂」按鈕後方直接顯示了供使用者選擇的所有服務的網頁)，系統會使用 Service.ranking_hint.score 做為服務訂購服務的信號之一。服務頁面中的分數越高，服務就會顯示。

注意：Google 可能會搭配 ranking_hint.score 以外的使用者信號，並且重新排序與 ranking_hint.score 指定的值不同的順序。

注意： ranking_hint.score 不得為負數。如果為「商家」的至少一項服務設定 ranking_hint.score，請為這個商家的所有服務設定其中一項。

範例

某商家有 3 項服務「剪髮」、「著色」、「Scalp 按摩和髮型」，以下是他們偏好的訂單：

1. 剪髮
2. 頭皮按摩與理髮
3. 著色

服務動態饋給可以指定如下：
