Product pictures play a key role in (b).

A. improve the conversion rate.

B. increase the click rate.

C. increase the unit price of customers.

D. increase the flow.

In fact, this problem is not difficult to understand. An advanced cover picture can often attract people to click on your store or link. Pictures are much more authentic than words. Consumer photography pays more attention to artistry. Pictures can directly reflect the appearance or practicality of goods, stimulate consumers' sensory nerves and stimulate consumers' desire to buy and possess.

People are very curious. If the cover picture captures the customer's heart, her curiosity will prompt him to open more content, which will increase the click-through rate and the customer's unit price will not increase.
