The biggest, most expensive and least forgiving GEO in the world. Here is how to buy it without overpaying.
Advertising in the United States means competing in the largest and most expensive digital ad market on earth, where every impression is being bid on by someone with a bigger budget and a longer history in the GEO. That is not a reason to avoid it. US traffic carries some of the highest purchasing power of any market and the conversion values reflect it. It does mean being deliberate about format choice, vertical fit and creative quality in a way that lower-competition GEOs forgive.
TL;DR
- Market size: US digital ad revenue reached 294.6 billion dollars in 2025, with programmatic at 162.4 billion dollars, up 20.5 percent year on year.
- Best formats: On Mondiad, in-page push, classic push and banner are the most popular formats for US traffic. Native fits consideration offers and popunders add volume.
- Best verticals: On Mondiad, software offers (VPN, cleaners) lead on push formats and adult offers lead on banners. Finance and insurance, e-commerce, health, gaming and iGaming, and dating are also worth testing.
- Playbook: Diversify formats, refresh creative constantly, optimize at source level and budget for a longer learning phase.
The US market in numbers
The scale is hard to overstate. IAB reported full-year 2025 US digital ad revenue of 294.6 billion dollars, up 13.9 percent, with programmatic spend reaching 162.4 billion dollars, up 20.5 percent year on year. That follows US internet advertising revenue of 258.6 billion dollars for full-year 2024, a 14.9 percent increase and the strongest growth since 2021.
Per capita, the United States leads the world. Total US ad investments were equivalent to 1,246 dollars per person in 2024, compared with 876 dollars in the UK and a global average of around 140 dollars across all channels, per DataReportal’s global advertising trends report.
Mobile is where the budgets are moving. Total US mobile ad spending was forecast to reach 228.11 billion dollars in 2025, with in-app advertising projected at 187.78 billion dollars, or 82.3 percent of the total.
Programmatic buying accounted for 82.4 percent of digital ad spend globally in 2024, and US programmatic revenue alone grew 20.5 percent in 2025.
The summary: high volume, high value, high competition. You pay more per impression than anywhere else and earn more per conversion than almost anywhere else.
Best ad formats for advertising in the United States
Format choice matters more here than in most GEOs, because a saturated audience punishes the wrong pick quickly. On Mondiad, the most popular ad formats for US traffic are in-page push, classic push and banner. The ad formats comparison guide covers the mechanics of each format, and the table below maps them onto US buying conditions.
| Format | Best use in the US | Priority |
|---|---|---|
| In-page push | Software offers (VPN, cleaners), urgency offers, iOS reach | Start here |
| Classic push | Software offers, re-engagement and subscription offers with recurring value | Start here |
| Banner | Adult offers, retargeting, frequency and brand recall | Start here for adult |
| Native | Finance, insurance, health and any offer needing context | Test for consideration offers |
| Popunder | Volume at target cost per action, iGaming, utilities and downloads | Scale phase |
In-page push
In-page push is one of the most popular formats on Mondiad for US traffic, and software offers such as VPNs and cleaner apps are its most popular vertical. It delivers notification-style messaging inside the page, so it reaches iOS users and browsers where classic push subscription is unavailable. Given the iOS share of the US market, that coverage gap matters more here than in most GEOs. It also performs well for time-sensitive messaging such as limited-time discounts, flash promotions and app install campaigns. Specs for each format are on the Mondiad ad formats page.
Classic push
Classic push is the other push format US advertisers use most on Mondiad, and software offers (VPNs, cleaners) lead here too. It also remains effective for re-engagement and subscription-based offers. Because you are reaching a user who has already opted in, intent is higher and quality tends to be better than cold traffic. Click and impression costs are higher than in emerging markets, but so is lifetime value, so use it for offers with repeat-purchase or recurring-revenue potential where the higher acquisition cost is recovered over time. On Mondiad, subscription age targeting lets you choose how recently users subscribed, so you can test fresh subscribers separately from older lists.
Banners
Banners are among the most popular formats on Mondiad’s US traffic, and adult offers are the vertical that drives them. For mainstream advertisers, banners work best as a support format: retargeting warm audiences, maintaining frequency across a campaign driven by other formats and brand-building where recall matters more than immediate clicks. If you are building creative, the banner ad sizes reference guide covers the dimensions worth producing, and what ad formats give the best results in 2026 puts the full mix in context.
Native ads
Native is the format to test for offers that need context, and the reason is audience fatigue. American users are among the most heavily advertised-to audiences in the world, and banner blindness is a measurable, well-documented effect. Native creative sidesteps it by matching the form and tone of the surrounding content. It works particularly well for offers that need a moment of context before the click: finance products, health offers, insurance comparisons and subscription services. If your offer requires the user to understand something before acting, native is where to start.
Popunders
Popunders remain the volume format for US campaigns optimizing toward cost per action. iGaming, software and utility installs, streaming and downloads, and dating offers all perform because the format delivers full attention at a lower cost than premium placements. The key in the US is source-level optimization, since popunder traffic quality varies more widely here than the format’s reputation suggests. Campaigns that whitelist aggressively outperform campaigns that do not.
Best verticals for advertising in the United States
On Mondiad, US demand is clearest in two places: software offers, especially VPNs and cleaner apps, are the most popular vertical on in-page push and classic push, while adult offers lead on banners.
Software, VPN and cleaner apps
This is the most popular vertical on Mondiad’s US push traffic. The US has a large, privacy-conscious, subscription-comfortable consumer base. VPN services, cleaner and other mobile utility apps, security software and productivity tools convert steadily, and the recurring revenue model makes higher acquisition costs sustainable. In-page push and classic push are the natural pairing: classic push for Android, in-page push for iOS, with popunder added for volume.
Dating and adult
Adult offers are the most popular vertical on Mondiad’s US banner traffic. Dating remains a dependable US vertical with high volume and well-understood creative patterns. Both work across formats, and a mix of banner, in-page push, classic push and popunder gives you enough reach to find the placements that register users at your target cost.
Finance and insurance
Finance and insurance carry some of the highest payouts in the US market. Personal loans, credit offers, insurance comparison, debt consolidation and investment platforms all carry payouts that comfortably absorb US traffic costs. Native is the natural pairing, since these offers benefit from editorial-style creative that explains the value before asking for the click. Classic push is the other format worth testing early, as it is the starting format Mondiad recommends for finance and crypto campaigns.
E-commerce and retail
Retail is one of the most competitive ad-spending categories in the US, which is exactly why timing matters. Seasonal campaigns around major shopping periods deliver some of the strongest returns available in this GEO.
Health and wellness (nutra)
Supplements, fitness programs, telehealth services and wellness subscriptions all perform well with US audiences, particularly through native placements. This vertical demands careful compliance attention, since US advertising standards around health claims are strictly enforced, but the conversion values justify the extra care.
Gaming and iGaming
Mobile gaming is a major category in the US, and in-app advertising dominates the mobile ad mix at over 82 percent of spend. Gaming offers convert well across popunder and classic push, the combination Mondiad recommends for iGaming launches. For iGaming specifically, regulation is state by state, so geo-targeting precision is a legal requirement rather than just an optimization tactic.
How to compete in a saturated market
- Diversify your format mix: Audience fatigue sets in fast. A campaign running one format against one audience will see performance decay within weeks. Rotating between in-page push, classic push, banner and native placements keeps frequency manageable and extends campaign life.
- Refresh creative constantly: US creative burns out faster than in most GEOs. Plan a rotation schedule from day one rather than reacting once click-through rate has dropped.
- Optimize at source level: With this much inventory available, the gap between your best and worst performing sources is usually larger than the gap between your best and worst performing formats. Whitelist and blacklist aggressively.
- Segment by state where it matters: Purchasing behavior, regulation and seasonality vary significantly across states. In regulated verticals, ignoring that creates real compliance risk.
- Build for mobile first: With ad budgets moving to mobile and in-app taking the overwhelming majority of mobile spend, a desktop-first landing page is a self-inflicted conversion problem.
- Expect a longer optimization period: US campaigns typically need more data before they stabilize than campaigns in lower-cost GEOs. Budget for the learning phase rather than killing campaigns too early.
Frequently Asked Questions
Which ad format works best for advertising in the United States?
On Mondiad, in-page push, classic push and banner are the most popular formats for US traffic. Software offers such as VPNs and cleaners lead on the push formats, and adult offers lead on banners. Native is the format to test for offers that need context, such as finance and health, and popunders remain the volume format for campaigns optimizing toward cost per action.
Is US traffic worth the higher cost?
Usually yes, because purchasing power is among the highest of any market. Total US ad investments were equivalent to 1,246 dollars per person in 2024 against a global average of around 140 dollars. You pay more per impression and earn more per conversion, so the decision comes down to whether your offer payout supports the CPM.
Which verticals are most popular in the United States?
On Mondiad, software offers such as VPNs and cleaner apps are the most popular vertical on in-page push and classic push, and adult offers lead on banners. Finance and insurance carry some of the highest payouts, and e-commerce and retail, health and wellness, gaming and iGaming, and dating are also worth testing. Finance and health pair best with native, and gaming and iGaming pair best with popunder and classic push traffic.
How often should creative be refreshed on US campaigns?
More often than in most GEOs. Audience fatigue sets in quickly in a saturated market, so plan a rotation schedule from day one rather than reacting once click-through rate has already dropped.
Does the United States need state-level targeting?
For regulated verticals such as iGaming it is a legal requirement, not an optimization tactic. For everything else, purchasing behavior, seasonality and competition vary enough across states that treating the country as one uniform GEO leaves performance on the table.
