Formats · specs & rules
From "I need the maximum number of clicks" to "I want the most expensive slot on the page" — seven formats cover the whole range. Billing model, reference price, creative sizes and review rules are all on this page.

|---|---|---|---|---|
| Popunder | CPC / CPM | $0.60 – $4.20 | None (landing page only) | Desktop + mobile |
| Push | CPM | $0.02 – $1.40 | 192×192 icon, 360×240 image | Chrome / Firefox / Edge / Safari 16+ |
| In-page push | CPM / CPC | $0.03 – $1.10 | Icon + title + one-line copy | Mobile first, all devices |
| Native | CPC / CPM | $0.05 – $2.20 | 1200×628 image + title + description | News / blogs / landing pages |
| Video | CPM / CPV | $0.15 – $3.40 | MP4 ≤ 30s, 16:9 or 9:16 | Desktop + mobile + CTV |

Format by format
Choose in this order: decide the goal (volume, quality, brand, re-engagement), then pick the two or three formats that serve it. Turning all seven on at once is a way to let the cheapest format eat the budget.
Opens behind the page on any click, taking no slot. The cheapest way to buy clicks, and the most demanding on your landing page's ability to hold attention.
Reaches subscribers after they leave, so one opt-in keeps paying for months. The headline decides click rate far more than the image does.
A card in the corner of the page — no subscription, no permission prompt, visible to every visitor. The most practical top-up for iOS-heavy mobile traffic.
Recommendation units built to the host's layout. Click rate and conversion quality usually beat banners, which makes it the right choice when the product needs explaining.
Pre-roll, floating and rewarded, billed per completed view or click. Highest unit price and highest production cost — test three cuts with different first three seconds before scaling.
Standard IAB sizes: steady, predictable, the base layer of direct budgets. Weak on its own — it needs native or video next to it to matter.
No site and no domain: one link absorbs clicks from social, newsletters and private channels. Usable by both sides, and the fastest way for a new account to prove something.
Volume: popunder + push. Quality and brand: native + video. Mobile top-up: in-page + banner. Run the stack inside one campaign and the system allocates budget by live eCPM.
Creative specs
Review returns a verdict in under two hours. Nine out of ten rejections come down to these six rules — check them before uploading and skip a whole round trip.
60 characters max in English (30 in Chinese). No "official", "the only", guaranteed results or medical claims.
JPG / PNG / WebP, 2MB per file max. Icon 192×192, main image 1200×628, banners in IAB sizes.
MP4 (H.264), 30 seconds max, key message in the first frame. Prepare 16:9 and 9:16; CTV placements need separate approval.
Must load, must work on mobile. No automatic downloads, no forced redirects, no fake close buttons or countdown timers.
Finance, crypto, gambling and health need the relevant local licence or approval. Without it the campaign doesn't go live.
No minors, no non-consensual or violent material, and the target market's rules apply. Some geos are closed to adult by default.
Drop up to 200 images or 20 videos at once. Every size each format needs is cropped and previewed automatically, and headline counters turn red past the limit so nobody counts characters by hand.
Format FAQ
For volume, popunder. For quality, native. With a limited budget and one vertical, start on popunder to find volume, then bring native in to pull the cost down — the cold-start logic is different for each.
Yes, but don't start there. Too many formats in one campaign lets the cheapest one eat the budget. Open two, let them run three days for a baseline, then add one at a time.
The verdict names the exact rule that failed. Fix it and resubmit — the account isn't penalised. Five rejections in a row trigger a manual account review, usually inside one business day.
No credit card to open an account, from $100 to start. Publishers don't need a layout change either: one async snippet and the first impression revenue lands today.
