Tạo chỉ số trước đây

Chỉ số trong quá khứ cung cấp các chỉ số về hiệu suất trước đây của từ khoá trên Google Tìm kiếm, bao gồm:

• Số lượt tìm kiếm trung bình hằng tháng (12 tháng qua)
• Lượng tìm kiếm ước tính hằng tháng (mỗi tháng)
• Mức độ cạnh tranh
• Chỉ số cạnh tranh
• Phân vị thứ 20 của giá thầu
• Phân vị thứ 80 của giá thầu

Bạn có thể sử dụng chỉ số lịch sử để giảm một tập hợp lớn các từ khoá xuống kích thước có thể quản lý dựa trên hiệu suất. Nếu bạn đã biết các từ khoá bạn muốn sử dụng, bạn có thể bỏ qua các chỉ số trước đây và chuyển thẳng đến chỉ số dự báo.

Tạo chỉ số

Để tạo chỉ số trước đây, hãy gọi KeywordPlanIdeaService.GenerateKeywordHistoricalMetrics bằng các tham số mà bạn muốn đưa vào.
