Priya 设置 CAPI 转化追踪已经两周了，但她发现 CAPI 转化的匹配率一直偏低。她首先应该检查什么？

Priya should first check data quality, including misspellings, special characters, and empty fields. Low match rates in CAPI (Conversions API) often stem from discrepancies between the customer data sent to the platform and the data the platform has on record. Even minor inconsistencies in customer information (like email addresses or phone numbers) can prevent successful matching. Ensuring clean, consistent, and correctly formatted data is crucial for CAPI to accurately attribute conversions. Campaign status, API status, and conversion attribution windows are important for overall tracking but are less likely to be the primary cause of a low match rate specifically, which points directly to issues with the data itself rather than the system's operational status or attribution logic.
