How do half-width characters affect ASO (App Store Optimization)

App Name and Subtitle

The 100-character keyword setting in the AppStore developer backend and the character limit for names and subtitles in the app store have certain restrictions. Using half-width characters can display more key information in limited space. For example, an application named "Travel Guide APP - Explore the World" can fully express the core functions of the application using half-width characters, improving the exposure rate of the application in search results.

Keyword Optimization

Keywords are the core of ASO. When selecting and setting keywords, using half-width characters can improve the accuracy and matching degree of keywords. The search algorithm of the app store usually matches applications according to the half-width keywords entered by users. For example, if a user enters "game" (half-width) in the search box, applications containing the half-width keyword "game" will have a greater chance of being searched.

Description

The description of the app can help users better understand the functions and features of the app. Using half-width characters can make the description clearer and easier to read, improving user's impression of the app. At the same time, reasonable layout of half-width keywords can improve the ranking of the app in search results.

Half-width characters play an important role in the mobile Internet advertising industry and ASO. Understanding and correctly using half-width characters can improve the efficiency of information delivery, optimize advertising placement results, and improve the ranking of applications in the app store.
