The calculation formula for Taobao Express promotion is as follows:

1. Express deduction formula: actual deduction = next bid x next quality score / your quality score + 0.01 yuan.

2. Traffic value calculation formula: traffic value = profit from a transaction / traffic required for a transaction.

3. An implicit formula: Express ranking = bid * quality score.

4. Express investment ratio calculation formula: input-output ratio ROI = total transaction amount / cost.

5. Turnover = customer unit price * number of transactions.

6. Number of transactions = traffic * conversion rate.

7. Traffic = Express delivery fee / average click cost.

8. Profit = turnover * profit margin = customer unit price * number of transactions * profit margin = customer unit price * traffic * conversion rate * profit margin = customer unit price * conversion rate * profit margin * direct train delivery fee / average click cost.

9. Direct train benefit = (transaction amount on the day x product gross profit margin) all the way through the cost.

10. Traffic value = single profit x conversion rate.

11. Direct train display volume = click volume ÷ (click rate / 00).

12. Click rate = (click volume ÷ display volume) x 100%.

13. Average display ranking = sum of each display ranking / display volume.

14. Average click cost (PPC) = cost ÷ click volume.

15. Average click cost (CPC) = total cost ÷ click volume.

16. Cost = average click cost x click volume.
