Through Train is a pay-per-performance advertisement, and its payment method is CPC. Through Train uses competitive bidding to allow sellers' products to be displayed at the top of the search results page, which directly affects the click-through rate of the products. Competitive bidding refers to obtaining a favorable ranking position on the website through competitive bidding, so as to achieve the purpose of increasing product exposure and traffic.

Since Through Train is paid by click, the system will only deduct fees for this click when the buyer is interested in the product and clicks to learn more details. If the buyer only browses and does not click on the product to view it, no fees will be deducted. Through Train is designed to help sellers quickly and accurately locate overseas buyers and expand product marketing channels.
