Common creative specs

The upload screen in your platform always shows the exact sizes and limits it accepts. The usual specs are:

  • Display — standard IAB sizes such as 300×250, 728×90, 160×600, 300×600, 320×50 and 970×250. JPG, PNG, GIF or HTML5, static or animated.
  • Push — short title and body text, an icon and an optional large image. Keep texts short; push has strict character limits.
  • Native — headline, description and an image (1200×628 is the common landscape size), with a sponsored label.
  • HTML5 — a ZIP bundle, kept small (200 KB is the usual limit).
  • Video — VAST tags or MP4 files, 6, 15 or 30 seconds, skippable or non-skippable.
  • Pop-Under — a landing page URL. For pop-under, the page itself is the ad.

Pricing models

Formats are bought on CPM or CPC depending on the format, and campaigns can optimize automatically for CTR, CPA or CPV.

Multi-format campaigns

Advertisers run every format from one account, sharing targeting, budgets and reporting without duplicating setup.

Brand safety

Category and domain blocking, whitelists and blocklists, and pre-bid traffic checks apply across formats — see How AI-powered fraud detection works.
