Rewarded Playables

Supported Formats

Marketplace auctions allow only playable ads and VAST video ads. We support the following formats for interstitial/rewarded video inventory:

  • Rewarded Video: VAST 2.0 & VAST 3.0. We do not currently support VPAID.
  • Rewarded Playable: MRAID 1.0 and MRAID 2.0. We do not currently support MRAID 3.0.

Ad Requests and Your Responses

OpenRTB and MoPub

MoPub closely aligns with the OpenRTB 2.3 spec, designed by IAB. We have created some extensions within our current spec to provide you with extra fields that may not exist within IAB’s OpenRTB 2.3, such as Object: video.ext, which you can use to identify Rewarded Video requests. Refer to the MoPub OpenRTB spec for more information.

Rewarded Video Requests with Playables Blocked

You may receive requests for rewarded video if the publisher has playable ads blocked. For such requests, you can choose to serve VAST ads or to respond with a no-bid.

You will not, however, receive a rewarded playable request if rewarded video is not supported. Both the banner and the video object will always be present.

Close Button, Timer, and End Card Assets

  • Close Button: Do not return a close button, because the MoPub SDK handles the close button after 30 seconds. Do not return your own custom close button or leverage the useCustomClose() function for rewarded inventory, because this may cause problems with the ad.

  • Timer: A 30-second countdown timer is present throughout the 30-second video experience for rewarded playables. Do not return your own countdown timer, because this will cause problems with the ad.

  • End Card: We recommend that you do submit an end card for rewarded video (including playables) because we have seen 20% higher CTR when an end card is included.

Identifying Bid Requests that Support Rewarded Video and Playables

Bid requests that support rewarded video and rewarded playables have the following fields:

  • The video extension field videotype is present (as in: bid_request.imp.video.ext.videotype) and videotype is set to rewarded.

  • The video extension field skip is present, and set to integer 0 (as in: bid_request.imp.video.ext.skip).

  • Banner object is present and 13 is not blocked in the banner battr field (as in: bid_request.imp.banner.battr != 13).

Your Creatives

Aspect Ratios

MoPub supports all video aspect ratio sizes, including 16:9, 4:3, 3:2, and 16:10, as per the IAB Digital Video Ad Format Guidelines. We recommend the following:

  • Send the 16:9 landscape ratio for both 480×320 (fullscreen phone) or 1024×768 (fullscreen tablet) MoPub ad sizes.

  • Send the 4:3 aspect ratio for iPads.

  • If you plan to adjust the aspect ratio based on the device screen dimensions, make your playable as responsive as possible. A better interactive experience can improve your conversions.

Higher Resolution to Improve Graphic Quality

You may use a higher resolution creative, such as 2x - 640x960, to improve graphic quality if you wish. Keep in mind that this increases the overall weight of the creative. Heavier creatives may not clear (render) in time for users. With a lighter creative (in weight), you have a greater chance of rendering the ad in time.

We recommend the following creative weights for MRAID playables:

  • Suboptimal: 200-300kb
  • OK: 700kb
  • Optimal: 1mb+

User Experience: Non-Skippable Playable Ad When Video is Replaced by Playable Ad

If DSPs serve a non-rewarded playable fullscreen interstitial to a user, the user can engage with the creative. If DSPs respond with a playable ad for a rewarded video request, the user opts into the experience for a minimum of 30 seconds. Users cannot exit the ad until 30 seconds have passed, even if the DSP has responded with a rewarded playable ad that is less than 30 seconds.

A user who clicks on the Call to Action (CTA) button (such as ‘Install Now’) when the video ends at around 30 seconds is forwarded to the destination landing page within the app itself or in the app or play store. However, once the app is re-opened, any pending duration of the 30-second experience continues to play until the 30-second mark is reached. For example, if a DSP submits a video for 20 seconds, the user can click on the CTA button to install after 20 seconds, install the app from the app store, and, upon returning to the publisher app, complete watching the pending 10 seconds of video until the full 30 seconds of video is complete.

We recommend ensuring that the duration of the game play is at least 30 seconds. Because the user is opting into a minimum 30-second experience (before the close button can appear), you’ll want to engage them for the entire time. Many of our existing DSP partners take advantage of the 30 seconds opt-in experience by customizing and tailoring the playable ad for additional time. For example, one of our DSPs has a threshold that kicks in a video or new animation after three seconds of no engagement on the playable screen.

Additional Best Practices

Building Playable Ads

We recommend building your creatives in-house to more closely align with the user action and engagement depth, and to target the user level in a meaningful way. For example, you can add more data points to the creative to track where the user is most engaged (for instance, you can be notified if the user has played for five seconds, finished Level 5, or is still engaged).

Another critical variable you can control by building your own creatives is the moment at which the CTA displays; this directly impacts the engagement aspect. We recommend displaying the CTA toward the end of the 30 seconds, as opposed to, for instance, at 28 seconds. This way the user is not distracted from the experience earlier than intended.

Targeting Rewarded Video and Interstitial Inventory for Playables

We recommend that you begin with limited targeting and remain open to as many auctions as possible. Rewarded video (playable) support is unlike any other, and frequency for DAU and MAU (finding the same user again) will change. In light of this, do not limit algorithms for identifying good users to only a week or so. Instead, allow the campaigns to run for three weeks so they can be statistically significant for testing.

When reviewing your success in rewarded video, account for larger conversion windows. After a significant period of running on rewarded inventory, you can optimize based on your advertisers’ respective KPIs.

Testing Your Creatives

We recommend testing all your creatives before you begin running them. Refer to our detailed walk-through for testing your creatives.

FAQs

No, only playable ads and VAST video ads are supported. Any other creatives will not be eligible to participate in the auction.

Yes. You may receive a request for rewarded video if the publisher has playable ads blocked. You can choose to serve VAST ads to these types of requests or to respond with a no-bid.

Not currently. Users cannot exit the ad until 30 seconds have passed.

The user can click on the Call to Action (CTA) button (such as ‘Install Now’) if the video ends prior to 30 seconds, and be forwarded to the destination landing page either within the app itself or at app store or play store. However, once the app is re-opened, the pending duration of the 30-second experience will continue to play until the 30-second mark is completed.

No. DSPs do not return a close button or a countdown timer. DSPs do include an end card. Refer to Close Button, Timer, and End Card Assets.

MoPub does not have any specific recommendations for creative vendors. A few of our DSP partners create their creatives tags in-house to allow for more flexibility and control. Refer to Building Playable Ads.
