Web Push Notifications Advertising
Web push ads 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?
Three layers, none of them a black box. Before the auction, the bidder rejects requests from iframes, datacenter ASNs, hammering IPs and malformed user-agents; proxy/VPN traffic is blocked on SSP supply and targetable by a flag on direct placements. On the click, a JavaScript challenge by Kaminari — an independent antifraud vendor — filters bots before the redirect. Daily, every placement is scored on outcomes: enough clicks with zero conversions for any advertiser, or the same email registering across accounts, and it is blocked network-wide. Confirmed fraud is refunded.
Can I whitelist or blacklist sources?
Yes — whitelist and blacklist by source ID, app ID and zone, per campaign. There is no optimizer that silently drops sources for you. If you want automation, Auto CPA re-bids per source toward your target cost per conversion and leaves the source list under your control.
Can I pay per conversion instead of CPM/CPC?
Yes, two ways. Auto CPA bidding is self-serve on every format: you set a target cost per conversion and the bidder tunes CPM/CPC bids per traffic source to hit it. CPA pricing, where you pay a fixed price per conversion and nothing otherwise, is in beta and available on request — it runs on direct-publisher In-Page Push and Popunder inventory only, so we agree the conversion event and geos with you first. Both require S2S postback conversion tracking.
