設定服務順序

重點：如果您未遵循這項設定，系統會按任意順序顯示服務。

規範

如要影響特定商家的服務顯示順序，請在服務動態饋給中為各個 Service 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;
}

如果顯示了多項服務 (例如：直接在「書籍」按鈕之後顯示的網頁)，其中有可供使用者選擇的所有服務，系統會使用「Service.ranking_hint.score」做為向「服務」排序的信號。「服務」將會在頁面上顯示分數越高。

注意：Google 可能會將其他信號與 ranking_hint.score 一併使用，並依據 ranking_hint.score 所指定的值重新排序。

注意：ranking_hint.score 不得為負值。如果您至少為同一個商家的「服務」設定 ranking_hint.score，請為這個商家的所有「服務」設定一個「服務」。

範例

商家提供 3 種服務，分別是「剪髮」、「染髮」和「剪髮」；偏好的順序如下：

1. 剪髮
2. 頭皮按摩和剪髮
3. 著色

服務動態饋給的指定方式如下：
