Payment Link Optimization Practices for NetEase Cloud Music

This article introduces the payment link optimization solutions implemented by NetEase Cloud Music's membership team in 2023. The payment link carries the main transaction flow for the Cloud Music business, covering member subscriptions, digital albums, merchandise, and various payment channels including Alipay, WeChat Pay, Douyin, and NetEase Pay.

Checkout Page Performance Optimization: The core checkout pages are built with React Native. The optimization approach addresses three stages: blank screen, First Contentful Paint (FCP), and Largest Contentful Paint (LCP). Key optimization techniques include: switching to main process on Android, implementing RN offline bundles, RN bundle splitting, using Hermes engine with bytecode, dynamic imports, and interface preloading. For mid-to-low-end Android devices, additional deep optimizations like RN pre-rendering, silent loading, and interface pre-request were implemented.

Optimization results: FCP rate +1.37pt, LCP rate +3.66pt, FMP loading time -800ms, Purchase UV +8.54%, SKU exposure rate +8.26%, Conversion rate +0.08%.

iOS IAP System Optimization: IAP data pre-fetching improved cache hit rate from 0% to 96.52%, reducing -4 errors to zero. Consumable product payment success rate increased by +1.35pt, subscription product by +0.46pt. StoreKit 2 migration provides UUID-encoded receipts with OrderId, cross-device order synchronization, and eligibility checking for promotional offers.

Android Third-party Payment SDK Updates: Updating payment SDKs (Alipay, WeChat, UnionPay, Douyin, NetEase Pay) resulted in +3.29% payment success rate improvement. The verification process involves traffic splitting, grayscale rollout, and channel-based validation.

Payment Retention Strategy: IAP payment failure SMS reminder increased active purchase UV by +0.28%.
