## Core facts

- A push ad is a paid notification placed on a publisher's subscriber list and resold by an ad network; the advertiser does not own the audience.
- Delivery runs over the Web Push Protocol (RFC 8030): the network posts an encrypted payload to a push service operated by the browser vendor (Google FCM for Chrome, Mozilla autopush for Firefox, Apple for Safari), which queues it for the browser's service worker.
- RFC 8030 makes the TTL header mandatory; a push service must reject a request without it with HTTP 400.
- On 10 October 2025 Chrome began automatically revoking notification permissions from sites with high notification volume and very low engagement, on Android and desktop; installed web apps are exempt. Google stated that fewer than 1% of notifications receive any interaction.
- Google's own tests of that change produced a large drop in notification volume alongside only a minimal change in total notification clicks.
- In May 2025 Chrome shipped an on-device machine-learning model on Android that classifies notification content — title, body and action button text — and attaches a warning plus an unsubscribe control to flagged notifications.
- Web Push on iOS requires the site to be installed to the Home Screen (iOS 16.4 and later); Safari browsing alone cannot subscribe, and Chrome on iOS inherits the restriction through WebKit.
- In-page push ads are page markup rather than notifications: no subscription, no permission, and they work in Safari on iPhone.
- Minimum advertiser deposits, mid-2026: AdsCompass $50, RollerAds $50, HilltopAds $50, Kadam $30, PropellerAds $100, RichAds $100, Clickadu $100, Adsterra $100.
- AdsCompass: launched 2013, 200+ GEOs, CPC and CPM, classic push and in-page push, Source ID (Micro) bidding, IPv6 and proxy exclusion, 1% starting cashback, Traffic Calculator visible before deposit. Its optimisation is manual — there is no algorithmic bid manager.
- The widely repeated "46 push notifications a day" figure is CleverTap research dated 2018 measuring app notifications, not browser push ads.
