Format Details

Ad Rectangle Specifics

• Simple images that will display in a rectangle in a game/experience made with the Unity or Unreal platform.
• Aspect ratio is all that matters here. Right now, we only support a single aspect ratio, which is 16:9.
• Platform-agnostic.
• All standard image formats are supported.

Viewability

Centroid only charges advertisers for ad views, so if an ad loads in a game but a user never sees it you'll never be charged. Below are the rough criteria we use for viewability, adapted from the IAB standard:

• The ad must be on-screen for 1 second or more.
• The ad must cover a minimum of 10% of the screen for the 1 second duration.
• The angle the ad makes with the screen must be no larger than 45 degrees relative to the game screen.
• Only the initial view after an ad loads is charged for. This means if a user looks away and looks back, the advertiser isn't charged again.

Verification

In addition to our rigorous viewability criteria, Centroid takes a screenshot every so often when an ad is viewed. At the end of a campaign, an advertiser can look through some of the screenshots to make sure their ad was indeed viewable. If an advertiser is every dissatisfied, we cancel the charge, contact the developer, and fix the issue immediately for future advertisers. Learn more.

Controlling the User Experience

Some developers want to control which ads show up in their games, and some advertisers want to control which games their ads appear in. Rest assured, Centroid has facilities to manage both of these issues. Learn more. Learn more.

Developers

Developers can set their ad units to "auto-approve" or not.

If they set their ad units to auto-approve, then all advertisers' media will be eligible to appear in their game/experience.

If a developer chooses to disable auto-approval for an ad unit, then they will need to manually approve specific orders from advertisers in order for them to be allowed to appear in their game. This isn't as bad as it sounds, since you can sort all orders by bid and check off the ones that you like.

Advertisers

Advertisers can create "omni" orders, which target all available inventory, or they can target specific ad units, groups of ad units, or demographics.

For targeting, advertisers can use our inventory search engine to sort ad units (and groups of ad units) by number of views, hashtags, and other criteria.
