Web Push Notifications Advertising
Reach your audience system-wide. Subscribed users get a native OS notification even when the browser tab is closed — one of the highest-converting formats in performance marketing.
How it works
From bid to conversion in seconds
1
User subscribes once
When visiting a partner site, the user grants browser notification permission. From that moment they're part of the targetable audience.
2
Your ad is delivered system-wide
A native OS notification appears in the bottom-right (desktop) or notification tray (mobile) — even when the browser is closed.
3
Click → landing → conversion
CTR on engaged push audiences regularly exceeds 1–3%. Frequency capping prevents subscriber fatigue.

Why this format
Strengths of Web Push Notifications
- Reaches users even after they leave the publisher site
- High intent: subscribers have explicitly opted in to receive notifications
- Native look-and-feel — feels like a Slack/WhatsApp ping, not an ad
- Best-converting cold-traffic format for affiliates (iGaming, Sweepstakes, Crypto)
FAQ
Web Push Notifications — frequent questions
How do I get web push subscribers?
You don't — Adexium maintains a network of partner publishers who already collected millions of opt-in subscribers. You only buy delivery to those audiences.
Does Web Push work on iOS?
Native iOS web push works on Safari 16.4+ when users add the site to the home screen. For broader iOS reach use our Push In-Page format instead.
What's the difference vs Push In-Page?
Web Push fires system-wide even when the browser is closed (requires prior subscription). Push In-Page only displays while the user is browsing a partner site (no subscription needed).
How to avoid subscriber fatigue?
Set frequency capping (1/3/6/24h), use creative rotation (5–10 banners minimum), and refresh creatives weekly. Tier-1 audiences typically see 2–3 push impressions per day across all advertisers.
Does Web Push support Auto CPA bidding?
Yes — instead of a fixed CPC, set a target cost per conversion and the bidder adjusts bids per traffic source using real conversion data, cutting sources that run over your goal. Requires S2S postback tracking.

How does anti-fraud work?
Two layers of protection working in parallel. In-house antifraud uses ML traffic scoring, device fingerprinting, IP/ASN reputation, and behavioral analysis tuned for Telegram and web placements. Kaminari, our independent antifraud partner, adds verification cross-checking every impression and click against industry-wide fraud signals. Bot, incentivized, and invalid traffic is filtered automatically; confirmed fraud is refunded.
Can I whitelist or blacklist sources?
Yes — full whitelist/blacklist control by source ID, app ID, and zone. AI Source Optimizer can also auto-manage sources based on your KPI targets.
Can I pay per conversion instead of CPM/CPC?
Yes, two ways. CPA pricing: on In-Page Push and Popunder you set the price per conversion and pay only when it happens. Auto CPA bidding: on any format you set a target cost per conversion and the bidder auto-tunes CPM/CPC bids per traffic source to hit it. Both require S2S postback conversion tracking.
