特定网页的访问者

您可以使用 flexible_rule_user_list 将广告定位到访问过您网站的特定网页或版块的用户，这样您就可以定位比网站网域更具体的网址。

前提条件

如需创建和定位目标受众群体细分，您首先需要：

查看针对用户兴趣和地理位置投放广告的政策。有关用户的敏感信息不能用于创建受众群体。
设置 Google 代码。

如果广告客户希望根据移动应用行为创建用户名单，则应实现 Firebase SDK 或使用第三方 SDK 来跟踪应用内行为。

检索 Google 代码

所有 Google Ads 账号都只有一个账号级 Google 代码，该代码会在账号开通时自动创建。

您可以在 Google Ads 界面中按照帮助中心说明检索 Google 代码，也可以在 Google Ads API 中通过创建 RemarketingAction 来检索 Google 代码，然后使用 remarketing_action 资源发出 GoogleAdsService.searchStream 请求：

SELECT
  remarketing_action.id,
  remarketing_action.name,
  remarketing_action.tag_snippets
FROM remarketing_action
WHERE remarketing_action.resource_name = 'REMARKETING_ACTION_RESOURCE_NAME'

在网站或应用中添加 Google 代码

接下来，您需要在网站的所有网页上添加 Google 代码。详细了解如何向网站或移动应用添加 Google 代码。

如果您计划仅根据访问过的网页网址来构建细分受众群，则无需对 Google 代码进行任何修改。如果您使用自定义参数，则需要修改代码以加入这些参数，如编写代码和创建再营销名单的高级策略中所述。

您可以使用 Google Tag Assistant 验证代码植入情况。

内置 Google 代码参数

您可以使用内置的再营销参数 url__，根据用户在您网站上访问过的网址来定位用户名单，如网站访问者示例中所示。

自定义 Google 代码参数

您可以向 Google 代码添加自定义 Google 代码参数，以创建更精细的用户名单。

在创建自己的自定义参数之前，请查看预定义参数列表，看看是否已有适合您用例的参数。使用预定义的参数可以更轻松地与其他 Google Ads 再营销功能集成。

创建用户列表

此部分包含两个用户名单示例：访问过某网页且访问过另一网页的访问者，以及访问过某网页但未访问过另一网页的访问者。

访问过某网页并且还访问过另一网页的访问者

您可以使用 flexible_rule_user_list 将广告定位到访问过多个网页的用户。

首先，创建两个规则。然后，使用 AND 运算符将 flexible_rule_user_list 中的规则与 inclusive_operands 相结合。

用于创建灵活规则用户列表的代码示例
