关键字提示

借助 KeywordPlanIdeaService，您可以搜索与 Google 搜索广告系列相关的新关键字，或查找关键字的历史指标。

生成创意

使用 KeywordPlanIdeaService.GenerateKeywordIdeas为广告系列生成关键字提示。

您可以提供关键字和网址种子来生成提示。设置地理位置、语言和投放网络设置等定位参数，以缩小搜索范围。系统会返回搜索量数据等历史统计信息，帮助您确定是否要将这些关键字用于广告系列。对于熟悉 Google Ads 界面的用户，此功能类似于关键字规划工具。

您可以通过多种方式创建种子来生成新关键字：

对于描述您所宣传内容的字词或短语，请使用 KeywordSeed。这可以是您定位的一般业务类型（例如管道工），也可以是您提供的产品或服务（例如疏通排水管）。
对于与您的业务相关的网页或整个网站的网址，请使用 UrlSeed。网址种子仅定位到特定网址。如果没有匹配项，搜索会自动扩展到同一网域中的网页。

对于网址种子，超链接中的内容不会用于生成关键字提示。
对于关键字种子和网址种子，请使用 KeywordAndUrlSeed。

与仅使用 UrlSeed 相比，使用 KeywordAndUrlSeed 可以生成更多关键字提示。
对于整个网站，请使用 SiteSeed。给定顶级域名（例如 www.example.com），网站种子会根据公开信息生成最多 25 万个关键字提示。

如需缩小定位范围，您可以：

使用 GenerateKeywordIdeasRequest.language设置语言。如需了解有效 ID，请参阅语言常量。
使用 GenerateKeywordIdeasRequest.geo_target_constants设置地理位置。如需了解有效 ID，请参阅地理位置定位。
使用 GenerateKeywordIdeasRequest.keyword_plan_network设置网络。
使用 GenerateKeywordIdeasRequest.include_adult_keywords设置是否添加成人关键字。
使用关键字优化关键字 GenerateKeywordIdeasRequest.keyword_annotation。
使用 GenerateKeywordIdeasRequest.historical_metrics_options设置日期范围。

响应中的结果集支持分页。

系统会返回包含历史指标的提示，这些指标可用于过滤列表，以便用于预测。例如，您可能只想定位到搜索量高的关键字，以最大限度地扩大广告系列的覆盖面；或者，您可能只想定位到竞争得分较高的关键字，以提高品牌认知度。
