Displaying Interstitial Ads

These are the best times to display interstitial ads:

As soon as possible

Try to insert your first ad as soon you can in the flow of the app. This is probably the most important step you can take to maximize interstitial ad revenue.

At natural pauses in the app

暂停可能出现在关卡之间、游戏失败后，或用户在连续的游戏中达到某个特定时间点后。游戏过程中这些暂停或中断通常是用户最容易接受广告的时刻。 这将带来更好的广告表现和更高的 eCPM。

Also:

• Avoid showing ads when a user is very engaged in your app.
• If you show your first ad at minute five of a user session, you’ll fail to monetize users who spend one to four minutes in the app.
