We’re format agnostic and enable ad zones by position. Specific formats fall under respective positions (e.g. a Billboard is ‘Top’ and so is Pushdown while Footer is ‘Bottom’ position). Each creative has a unique position (with multi-positions grouped as ‘Custom’) and must match the impression’s allowed/available position. The available positions for each biddable impression are determined by publisher settings and real-time viewability qualification and changes from impression to impression. The bidder’s algorythm decides based on the creative positions and optimization settings which creative to serve.
The positions are part of our aggregate Real Time Canvas which only allows a single creative to win a bid and display. You always buy all available positions per impression and they are not auctioned individually.
We recommend running multiple creative in all positions as part of any campaign to optimize reach and delivery. You can use campaign priority settings to ensure that preferred units such as multi-position takeovers deliver first on all available inventory using single positions as lower priority backup to reach delivery goals.
When building multi-position takeovers they only serve on impressions that can actually render the entire creative which is only possible on some larger screen display inventory. To maximize reach and scale, especially when doing audience targeting, we recommend to run a set of different creative executions for each campaign. That way you can always reach your audience with a viewable high impact format. Takeovers can use sides and Billboards or Interstitials but you can also run the positions as stand alone creative (Skins, Billboard, Interstitial).
A complete audience buying creative set would include:
·Side Skins: 250×1050 (Left/Right) full responsive by width
·Overlay/Interstitial: 800×600 transparent/light box
·Expandable Footer: 990×100 collapsed + 990×500 expanded
·Takeover: Skins + Bilboard
·Takeover: Skins + Overlay
Generally Overlays/Interstitials have the highest engagement stats as they are ‘in your face’ in-view non-scrollable formats. However, not all publishers allow these types and/or video. Takeover style creative (e.g. Skins + Overlay) require all positions to be available on the publisher which reduces the inventory pool. It’s always best and recommended to run multiple creative types/formats with any high impact campaign to maximize reach.
