The conversion rate of the through train will have a certain impact on Taobao mobile search, but it is not a decisive factor.

The through train is an advertising tool under the Alibaba Group that helps merchants increase product exposure and sales on e-commerce platforms such as Taobao and Tmall. When a user enters a store through the through train ad and completes the purchase behavior, the system will record this conversion and use it as the performance data of the through train ad.

Taobao mobile search refers to users searching for products on Taobao mobile by searching keywords. The ranking of Taobao mobile search is determined by a combination of factors, including product sales, reviews, keyword matching, store reputation, etc.

Although the conversion rate of the through train can reflect the effectiveness of the advertisement, it is not the only determining factor of Taobao mobile search ranking. If a product has a high conversion rate, but other factors (such as product quality, service quality, etc.) are not enough to meet user needs, then it may not rank very high in Taobao mobile search.

Therefore, merchants need to consider a variety of factors to improve the ranking of products in Taobao Mobile searches, rather than just relying on the conversion rate of the through train.
