曉蕾很清楚應用程式商店資訊對 Google 應用程式廣告活動的影響不容忽視。她想和開發團隊攜手撰寫出成效最佳的商店資訊，吸引瀏覽的使用者下載應用程式。曉蕾和開發團隊應先檢查 Google Play 商店資訊中的哪三項要素？(請選擇三項)

For Google App campaigns, optimizing your app store listing is crucial for attracting users. Xiaolei and her development team should focus on three key elements in the Google Play Store listing: 1. 說明 (Description): A compelling and keyword-rich description helps users understand the app's value and can improve search visibility within the store. 2. 主頁橫幅/影片 (Feature Graphic/Video): This is often the first visual impression users get. A high-quality, engaging graphic or video can quickly convey the app's purpose and appeal, encouraging further exploration. 3. 圖示 (Icon): The app icon is a primary visual identifier. A well-designed, recognizable icon stands out in search results and on users' devices, influencing click-through rates. "下載按鈕" (Download button) is a standard UI element, not something to "write" or optimize in terms of content. "字型" (Font) is a design detail within the listing but less impactful than the content and primary visuals.
