How APK push delivery works (FCM)

An APK installs and registers with Firebase Cloud Messaging (FCM) on first launch. FCM mints a per-install token that uniquely identifies the device + app pair. The backend stores the token, segments it by user attributes (GEO, vertical, deposit state), and sends push payloads through the FCM REST API. Google's infrastructure delivers the payload to the device, where the Android system notification service displays it.

Several properties matter for affiliate performance:

• No browser dependency. The push arrives even if Chrome, Firefox, or any other browser is not running. The user does not need to have visited your domain recently.
• System notification surface. The push displays your app's icon, name, and (optionally) a custom large image. There is no "via Chrome" or "via Browser" tag — the notification looks identical to a Telegram message or a Sberbank alert. Users do not dismiss it as a browser nag.
• Notification channels (Android 8+). Each push is sent on a named channel that the user can selectively mute. Used correctly, this lets you separate transactional (deposit confirmations) from promotional (tournament announcements) and avoids opt-out cascades.
• Priority signaling. High-priority messages bypass Doze and App Standby on Android 6+, ensuring time-sensitive pushes (active campaign reminder, abandonment recovery) are delivered immediately rather than batched.

How Web Push delivery works

A PWA registers a Service Worker in the user's browser. The Service Worker subscribes to push via the Web Push API; the browser stores the subscription with the user's push service endpoint (FCM for Chrome, Mozilla Autopush for Firefox, Apple Push Notification service for Safari since iOS 16.4). Push payloads are sent to the endpoint URL, which routes them to the device, where the Service Worker fires a notification through the Notification API.

The architectural differences matter:

• Browser-mediated. The notification is technically displayed by the browser, not by an installed app. On most Android skins, the system attaches "via Chrome" or "via Browser" attribution to the notification — a text label users read and judge as low-quality.
• Service Worker reliability. Aggressive battery optimizers on Samsung One UI, Xiaomi MIUI, Oppo ColorOS, OnePlus OxygenOS, and Vivo FuntouchOS frequently kill the browser process, which deregisters the Service Worker. The user has to open the browser at least once for the worker to re-register and pushes to resume. Empirically, this drops effective push reach by 20–40% on these OEMs after 48–72 hours of inactivity.
• iOS limitations. Web Push works on iOS Safari only since iOS 16.4 (March 2023), and only when the user has explicitly added the PWA to the home screen and granted notification permission inside the PWA after install. For drive-by Web Push subscriptions from a normal browsing session — the dominant flow in affiliate marketing — iOS Safari simply does not support it.
• Subscription fragility. Clearing browser data wipes the Web Push subscription. Cleaner apps do this routinely. The user does not even need to clear cache deliberately for the subscription to disappear.

Why the open-rate gap is 3×, not 1.5×

The gap between 12% and 36% is larger than what a single factor would predict. It is a multiplicative effect of three independent forces:

1. Brand attribution

"Notification from CasinoXYZ" reads as a real product update. "Notification via Chrome" reads as something a website is trying to push at you. Users have learned to swipe away the second category. Empirical effect on open rate: ~1.4× lift on APK over Web Push, all else being equal.

2. Delivery reliability

If 30% of your Web Push subscribers stop receiving pushes after 72 hours (because their OEM killed the Service Worker), your effective audience shrinks. APK push delivery is FCM-managed and not subject to this — Android system services survive OEM battery rules. Empirical effect: ~1.3× lift from delivery reliability alone.

3. Notification channel UX

Web Push notifications all look the same — there is no first-party way to distinguish "you have a new bonus" from "your deposit was confirmed." On APK, channel grouping lets users mute the promotional channel while keeping transactional pushes audible — which means transactional pushes maintain their open-rate signal while promotional pushes opt out cleanly. Effect on overall open rate: ~1.6× lift.

1.4 × 1.3 × 1.6 ≈ 2.9× — close to the 3× observed empirically.

When Web Push still makes sense

Native APK push is not always worth the migration cost. Web Push can be the right answer when:

• Multi-platform audience. If iOS Safari (PWA-installed) plus Android browser is your primary surface, a unified Web Push pipeline is operationally simpler than maintaining APK + iOS native + Web Push separately.
• Light retargeting. If your push strategy is one or two messages per user lifecycle (welcome, abandonment), the absolute volume of opens may not justify APK distribution overhead.
• Compliance constraints. Some advertisers require browser-based push for audit reasons. Read the offer terms.
• iOS-dominant verticals. Dating in Tier-1, parts of Crypto — APK won't reach iOS at all.

Push optimization for affiliate traffic

Whether you go APK or PWA, push performance compounds with strategy:

Time by GEO

Schedule activation pushes in the user's local 18:00–22:00 window — peak engagement for casual mobile use. Send transactional pushes immediately regardless of time. Apkservice.mobi GEO routing applies the user's IP-derived timezone automatically.

Frequency caps

Above 3 promotional pushes per day, opt-out rates climb sharply and OEM-level "Don't Disturb" suggestions kick in. Cap at 2/day for the first week post-install, then 1/day for active users. Skip days with no real signal.

Event-triggered > scheduled

Pushes triggered by user behavior — abandonment after deposit step, inactivity past 48 hours, completion of a goal threshold — outperform broadcast pushes by 2–3× in click-through rate. Apkservice.mobi exposes both modes through the same configuration UI.

Channel hygiene

Separate at minimum a "transactional" channel (deposit confirmations, withdrawal alerts) from a "promotional" channel (bonuses, tournaments). Users mute the second more aggressively than the first; mixing them erodes transactional open rate over time.

Bottom line

For Android-dominant paid affiliate traffic in 2026, native APK push notifications outperform PWA Web Push by approximately 3× on open rate, with material reliability and brand-perception advantages on top. The gap is not closing — Web Push limitations on aggressive Android OEMs are getting worse, not better, as battery optimization arms races escalate.

If your push strategy is the difference between a 2× and a 4× LTV multiplier on the first week post-install, native APK is not optional. PWA Web Push is a reasonable supplemental channel for iOS or for low-volume tests, but the primary push surface should be APK.
