Policies

Banner ad guidance: 300x250

The 300x250 ad is the IAB medium rectangle that is available for both phones and tablets. While all AdMob/AdSense policies and the information on banner ad guidance still apply, we want to share specific guidance regarding this ad size due to its unique size and shape. For more information on banner ads, please visit the Google Developers site.

Below, you'll find some implementation guidelines and best practices. The examples will help to clarify some of the most frequently used 300x250 ad implementations and whether they are aligned with our policies in providing a good user experience.

While some of the implementations that we discourage may not specifically be against our policies, we may still take appropriate action on any invalid activity that they may cause. Not following these guidelines may lead to invalid activity and/or may result in Google disabling ad serving to your app. Please visit our Ad Traffic Quality Resource Center for more information.

Discouraged

Ad mimicking app content (against policy)

Ads should not mimic app content. They must be clearly distinguishable from the app content. For example, in galleries, ads must be clearly delineated that they are not a feature image in the gallery themselves.

Ad overlapping with app content (against policy)

Ads should not float or hover over app content. This includes placing the ad over a background that covers app content. Ads should not unexpectedly appear and cover app content.

Ad on screens with no content (against policy)

Ads should not be placed on a 'dead end' screen. Additionally, there must be a way to exit a screen without clicking the ad (for example, a 'back' or 'menu' button). Otherwise, the user should be notified that the home button will exit the app.

Ad adjacent to interactive elements

Close proximity of ads to other elements within an app is one of the biggest causes of accidental clicks. To avoid accidental clicks, banner ads should not be placed immediately next to interactive elements and app content, which can include (but is not limited to):

  • Navigational buttons, such as a "next" button.
  • Interactive content like a text chat box or an image in an image gallery.
  • On a game play screen where users are continuously interacting with the app.
  • A "close" button or something equivalent on an app exit confirmation screen.

Custom close or dismiss methods

Custom close or dismiss methods include but is not limited to, a custom X button, a custom close button, or text that indicates the user should click it to close the ad. These buttons or text should not overlap or be adjacent to the ad since those placements may cause a high volume of accidental clicks.

Other implementations and best practices

Pause or level complete screen

Placing a 300x250 ad on a pause or level complete screen may be compliant as long as you take care that users are not encouraged to or tricked into clicking on the ad to resume the app. The ad should also be distinguishable from other interactive elements on the the screen.

Clear representation of ad

Ads should be distinguishable from app content. It is recommended that you label, position, or represent ads in a way that lets users know that it's a sponsored ad and is not part of the app content. However, don't label ads with any messaging that encourages users to click on or view ads.
