App Store Connectとは？

App Store Connect is the central hub for all App Store operations. When it comes to screenshots, the platform enforces strict requirements. You must provide screenshots for at least one iPhone display size (6.7-inch or 6.9-inch). You can upload up to 10 screenshots per device size per localization. Accepted formats are PNG and JPEG, and images must match the exact pixel dimensions for each device class. App Store Connect also supports app preview videos (up to 3 per device size) and promotional artwork for featuring opportunities.

The screenshot upload process in App Store Connect is organized by device display size. You select the target device, then drag and drop or upload your images in the order you want them to appear. The ordering matters significantly — the first three screenshots appear in search results and are your primary conversion drivers. App Store Connect provides a preview of how your listing will look in search results and on the product page, which is useful for checking visual consistency across your screenshot set.

Beyond screenshots, App Store Connect is where you configure all listing metadata (title, subtitle, keywords, description), set up Product Page Optimization A/B tests, create Custom Product Pages for different audience segments, manage in-app purchases and subscriptions, view detailed analytics (impressions, page views, conversion rates by source), and handle the app review submission process. Understanding App Store Connect thoroughly is essential for any ASO strategy, as it is the tool you will use to implement every optimization.
