Category targeting（类目定投）
类目定投是 Sponsored Products 的手动定投方式，投的是一整个 browse node，而不是某个关键词或单个 ASIN，还可以叠加品牌、价格区间、星级、Prime 等 refinement 来收窄范围。
类目定投投的是一整个 browse node，可以叠品牌、价格带、星级、Prime 等 refinement 收窄。麻烦在报表：这些 refinement 全叠在一条 target 上，跑完只回一行数据、一个 ACoS，你分不清是哪个条件起的作用。ASIN 级还能看：product attribute targeting 的广告组，search term 报告会把出广告的页面 ASIN 放进 customer search term 列，但按 Amazon 的说明它只收录至少产生一次点击的词，是抽样不是全量。投前估流量池也难，Amazon 自己的接口只给 asinCounts 的 min–max 区间。另外星级只能填整数是估算接口的限制，target 本身可以填小数。实操上别叠：类目单投、类目＋价格带、类目＋品牌各开一条，再把跑出量的 ASIN 提成 product targeting。
关键数字
费率与规则以官方英文原文为准，保留原文：
- A Sponsored Products ProductCategoryTarget refines on category id, brand, price and rating greater/less than, and Prime eligibility, plus age range (toys and games) and genre (Books and eBooks); Sponsored Brands supports only category, brand, price and rating, and Amazon DSP the category id alone.
- The v3 targetable-ASIN-count endpoint (POST /sp/targets/products/count) restricts ratingRange to integers 0–5 and returns asinCounts as a {min, max} range, while the target refinement itself accepts decimals, as in Amazon's productRatingLessThan 4.5 example.
- Amazon's search term report documentation says alphanumeric entries in the customer search term column correspond to ASINs and the detail page where the ad displayed, for automatic and product-attribute-targeted ad groups, and that the report includes only terms producing at least one click.
