Browser push is the most misunderstood format in performance marketing. It is cheap, it is fast to launch, and it is almost impossible to scale without discipline. The advertisers who make push work treat it as a direct-response channel with hard guardrails — not as a lottery ticket.
1. The creative is the targeting
Push inventory is largely sold on a CPM basis across broad audience segments. That means your headline and icon do most of the qualification work. A generic "You have a new message" creative buys you a click from everyone and a conversion from almost no one. Specificity wins: the vertical, the device, the benefit, and the offer in the first six words.
Run at least five angles per GEO before judging performance. Kill the bottom three at 3,000 impressions, then reinvest into the survivor with two new hooks attached to the same promise.
2. Frequency caps are a budget control, not a suggestion
Push networks can deliver the same user dozens of times a day. Without caps, your reported CTR climbs while your conversion rate collapses and the source looks worse than it is. Cap at 1–2 impressions per user per day, 5–7 per week, and review the setting any time you raise bids.
3. Send traffic where the offer actually lives
The highest-converting push destinations are rarely homepages. A pre-lander with one promise, one proof element and one button consistently beats a full product page — especially on mobile, where the click arrives with zero context. Keep load time under two seconds on a mid-range Android device.
4. Bid by GEO tier, not by gut
Tier-1 GEOs (US, CA, UK, AU, DE) clear at multiples of tier-2 and tier-3 CPMs. A campaign that looks impossible at $1.20 CPM in the US can be very profitable at $0.18 CPM in Brazil — but only if your payment flow, language and support actually work there. Match the GEO to the offer before you match the bid to the GEO.
5. Measure post-click, not post-impression
Track conversion events server-side and reconcile them against spend daily. A push source with a 0.8% CTR and a 12% conversion rate will beat a 3% CTR source with a 2% conversion rate every time. Build the report around revenue per thousand impressions (RPM), not clicks.
Where to start
If you are new to the channel, launch three GEOs, two verticals and five creatives. Give the campaign 48 hours and enough budget for 20,000 impressions per combination, then cut everything that has not produced a conversion. That is the entire method — the rest is repetition.
