Pop ads and push notifications are the two ad formats most iGaming media buyers start with, and the question comes up in every new campaign: which one should get the budget? The honest answer is that they do different jobs. Pop ads buy volume and data; push ads buy attention from users who already said yes to notifications. The buyers who scale casino and betting offers use both, in the right order.
This comparison covers how each format works, how they differ on pricing models, volume and intent, and when to use pop, push or in-page push ads for iGaming ad campaigns.
What are pop ads?
Pop ads (popunders and pop-ups) open a full landing page in a new tab or window when a user visits or clicks on a publisher's page. A popunder opens behind the active window, so the user sees it when they return. There's no banner and no ad copy in between: the advertiser's landing page is the ad. Pop under ads (popunder ads) are the most common variant for performance campaigns.
Pop traffic is bought on CPM and delivers the largest volumes at the lowest cost per visit of any format. That makes it the standard format for testing new offers, GEOs and landers across ad networks. The main limitation is ad blockers, which stop part of pop inventory from showing. Our pop traffic guide for iGaming covers setup in detail.
What are push ads?
Push notification ads are short, notification-style messages (icon, title, one line of text) delivered directly to the user's device after users subscribe to browser notifications. They appear on the user's screen even when they're not on the publisher's site, which makes them strong for time-sensitive messages like match-day odds or limited bonuses.
Push advertising is usually bought on CPC or CPM through a push notification ad network, reaches a smaller audience than pop, and relies on the quality of the subscriber base: only users who opt in receive notifications.
Why does the choice matter so much in iGaming?
Online gambling is now a very large advertising market. H2 Gambling Capital puts global online gambling GGR at $293bn in 2024, 41% of all gambling, with online expected to pass 50% by 2030. Most of that play happens on phones: 58% of European online gambling revenue came from mobile devices in 2024. Pop and push are the two formats that reach mobile gamblers at scale outside Google and Meta, so the way you split budget between them shapes your whole acquisition cost.
How do pop ads and push ads compare?
| Pop ads | Push ads | |
|---|---|---|
| How it works | Full landing page opens in a new tab or behind the window | Notification-style message to opted-in users |
| Creative needed | No, the landing page is the ad | Yes: icon, title, text |
| Volume | Very high | High |
| Cost per visit | Lowest | Low |
| User intent | Low to medium; the user didn't choose to click | Medium; the user opted in and chose to click |
| iOS reach | Yes | Limited (in-page push fills the gap) |
| Best for | Testing, large volumes, new player acquisition | Bonus offers, match-day betting, reactivation |
| Main risk | Weak landers waste volume | Creative fatigue and subscriber burn-out |
How do pop and push differ in pricing models?
Pop is almost always bought on CPM: you pay per thousand pops shown, and each pop is a full page view of your lander. Push is usually bought on CPC, so you pay only when a user clicks the notification. That changes how you read the numbers:
- With pop, the key ratio is registrations per thousand impressions. A slow or weak lander wastes every impression you pay for.
- With push, the key ratio is deposits per click. A catchy headline can buy lots of clicks from users who never deposit.
In both cases, the only number that settles the argument is cost per first deposit, for push notifications and pop ads alike. Send your FTD postback to the network and compare formats on that, not on CPM or CPC.
How does iOS change the pop vs push decision?
Classic web push depends on browser notifications, which reach iOS users far less than Android users. That matters in high-value markets: StatCounter shows iOS at 65.2% of mobile use in Australia, 68.5% in Canada and 51.5% in the UK in August 2026. Pop reaches iOS users normally, and in-page push brings the push creative style to them. If your GEO is iPhone-heavy, plan for pop and in-page push, not classic push alone.
When should you use pop ads for iGaming?
- Testing new GEOs and offers. Pop gives you registration and deposit data within days, with broad reach and geo targeting down to country and region.
- Tier 2 and Tier 3 markets. Low CPMs keep cost per FTD under control where player value is lower.
- Casino offers with a strong lander. A bonus-led landing page does the selling.
- Building whitelists. Pop data shows which publishers and devices produce depositors before you scale anywhere.
When should you use push ads for iGaming?
- Sports betting around fixtures. Push notifications reach bettors in the hours before kickoff and at half-time. See our push ads for sports betting playbook.
- Bonus-led casino offers. Free spins and deposit matches fit the short push format.
- Reactivation. Push works well for bringing registered users back to make a first deposit.
- Scaling proven angles. Once pop has shown which GEOs and angles work, push extends them to warmer users.
Where does in-page push fit?
In-page push looks like a push notification but is shown inside the page, with no opt-in. It reaches iOS users and people who never accept notifications, which classic push can't. For many iGaming advertisers, in-page push ads are the third leg of the stack: pop for volume, push notification ads for opted-in users, in-page push for everyone else. Native ads and banners complete the mix for regulated markets. Read more in our in-page push guide.
What mistakes should you avoid with push and pop ads?
- Judging pop on CTR. Pop has no click; the lander is the ad. Judge it on registrations and deposits.
- Sending push traffic to a long advertorial. Users who click push notifications want the offer in one screen.
- Weak ad copy. Push ads examples that work name the match, the market or the bonus; generic copy gets ignored.
- Mixing devices. Split iOS, Android and desktop into separate campaigns for both formats.
- Ignoring frequency. Too many pops or pushes to the same user burns the audience and the budget.
- Letting creatives run too long. Push creatives fatigue within days; refresh them before CTR drops.
How do you combine pop and push in one campaign plan?
- Start on pop. Broad targeting in your GEO list, modest caps, SubID tracking on everything.
- Find what converts. Keep the GEO, device and publisher combinations that produce deposits; cut the rest.
- Extend to push and in-page push. Take the winning angles and offers to push creatives for warmer users and iOS reach.
- Optimise on deposits. Send the FTD postback so optimisation, including FTD Magnet AI, works toward depositors, not clicks.
- Rotate creatives. Push fatigue arrives fast; refresh every few days.
Pop ads vs push ads: which should you choose?
If you need data and volume from many traffic sources, start with pop. If you need warm users at the right moment, use push notifications. For casino and betting offers at scale, use both: pop to find what converts, push and in-page push to scale it. Traffic Nomads runs pop, push, in-page push, native and banner in one self-service account, built only for iGaming.
