Trường danh mục

Danh mục sản phẩm là một vùng chứa thông tin về sản phẩm của bạn. Mỗi sản phẩm riêng lẻ được mô tả qua một tập hợp trường sẽ được sử dụng khác nhau tùy theo cách bạn sử dụng danh mục của mình.

Có thể bạn đã có danh mục sản phẩm dành cho quảng cáo danh mục Advantage+ trên Facebook. Danh mục này chứa tập hợp các trường bắt buộc có thể được dùng làm nền tảng cho danh mục Thương mại của bạn.

Hãy sử dụng hướng dẫn này để tìm hiểu thêm về các yêu cầu và đề xuất đối với trường bổ sung:

Cách sử dụng trường danh mục

Trường danh mục là công cụ để đánh giá chất lượng trải nghiệm cho khách hàng mua sản phẩm tại Cửa hàng trên Facebook hoặc các kênh Mua sắm trên Instagram của bạn:

  • Chi tiết sản phẩm - Trường danh mục được dùng để điền thông tin cho từng mặt hàng trên trang Chi tiết sản phẩm. Trường này bao gồm những thông tin quan trọng như mô tả sản phẩm, hình ảnh, mẫu kích cỡ/màu sắc, giá và danh sách cung ứng. Dữ liệu bị thiếu hoặc không chính xác có thể ảnh hưởng tiêu cực đến trải nghiệm người dùng, tác động đến tỷ lệ chuyển đổi thành mua hàng hoặc gây hiểu nhầm và hủy hoại niềm tin.

  • Logic kinh doanh - Một số trường được dùng để thông báo logic kinh doanh trên hệ thống phụ trợ của chúng tôi. Ví dụ: trường google_product_category xác định thuế suất áp dụng cho sản phẩm của bạn. Trường này cũng được dùng để xác định xem sản phẩm có đủ điều kiện áp dụng Quy định bảo vệ mua hàng hay không. Hạng mục sản phẩm không đúng có thể ảnh hưởng đến việc tính thuế và dẫn đến số tiền nộp thuế không chính xác.

Đối với Cửa hàng trên Facebook, khách hàng cần cung cấp tập hợp thông tin tối thiểu về các món sản phẩm của họ để tải lên Cửa hàng. Chúng tôi cũng yêu cầu tương tự khi bạn chạy chiến dịch quảng cáo danh mục Advantage+. Nếu doanh nghiệp của bạn đang sử dụng phương thức thanh toán trực tiếp, bạn cần có thêm trường bắt buộc khác, ví dụ: quantity_to_sell_on_fb. Tìm hiểu thêm về các trường được hỗ trợ cho danh mục của bạn.

  • Thông tin dành riêng cho hạng mục - Việc cung cấp thông tin chi tiết, chất lượng cao về sản phẩm giúp đảm bảo khách hàng có thể khám phá sản phẩm của bạn và đưa ra quyết định mua hàng sáng suốt. Nghĩa là cải thiện danh mục của bạn bằng cách cung cấp thông tin dành riêng cho hạng mục về sản phẩm và đảm bảo thông tin trong mỗi trường chính xác và cập nhật.

Khi sử dụng các trường dành riêng cho hạng mục, bạn phải cung cấp thông tin nhận dạng hạng mục - Hạng mục sản phẩm của Google hoặc Hạng mục sản phẩm của Facebook. Nếu cung cấp một trong các trường hạng mục này, bạn cũng có thể sử dụng các trường bổ sung dành riêng cho hạng mục đó để cung cấp thêm thông tin chi tiết về mặt hàng của mình.

Khi chúng tôi mở rộng tính năng của nền tảng, bạn có thể được hỗ trợ thêm về các trường hợp sử dụng khác từ trường danh mục.

Thuộc tính cơ bản phổ biến

Mỗi mặt hàng trong nguồn cấp dữ liệu sản phẩm của bạn đều hỗ trợ các thuộc tính cơ bản phổ biến sau.
