设置服务顺序

要点：如果您不遵循此设置，服务将按任意顺序显示。

规格

如需影响给定商家的服务的显示顺序，请在服务 Feed 中的每个 Service 上设置 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.
  float score = 1 [features.field_presence = EXPLICIT];
}

如果显示多项服务（例如，“预订”按钮后面的页面，其中显示了供用户选择的所有服务），系统会使用 Service.ranking_hint.score 作为订购服务的信号之一。得分越高，服务在页面上的显示位置就越高。

注意：Google 可能会除了 ranking_hint.score 之外，还使用其他信号，并会按照与 ranking_hint.score 所指定的方式不同的重新排序。

注意：ranking_hint.score 必须是非负数。如果您为某个商家的至少一项 Service 设置 ranking_hint.score，请为此商家的所有 Service 设置一个。

示例

某商家提供 3 项服务：“理发”、“上色”、“头皮按摩和理发”，首选订单如下：

1. 理发
2. 头皮按摩和理发
3. 填色游戏

可按如下方式指定服务 Feed：
