Waterfall Loading Mode

Managing ad availability is not easy. Keeping a balance between maximum ad availability while minimizing waste (network calls - which may affect user experience and data usage - and calls to mediated networks APIs - which may negatively impact eCPM if their inventory never gets to be shown to a user) can turn out to be harder than expected. In fact, often, it is simply guess work as you cannot predict ahead of time when a user will reach a moment in your application or game where it makes sense to show an Interstitial or offer the possibility to watch a Rewarded ad.

When you try to time your ad requests, this often results in not having a fill when you need it or having wasted fills that are never shown.
The CAS SDK provides an “auto-request” feature to address this problem.
By default, CAS SDK starts with auto-request enabled for all managers.

This means two things:

• When a user finishes watching an ad, CAS immediately tries to replace that ad.
• When a certain placement has trouble obtaining a fill (no traditional mediated network has available inventory and no programmatic demand is bidding within a predetermined amount of time), CAS continues trying to ensure that placement gets a fill by restarting the entire ad request process. This is performed in exponentially increasing time intervals to optimize the chances of getting a fill while minimizing usage of device resources.

However, you can choose to disable auto-request when you set Manual loading mode.

^1: Auto control load mediation ads starts immediately after initialization and will prepare displays automatically.

^2: Potential increase in revenue by increasing the frequency of ad requests. At the same time, it greatly affects the performance of the application.

^3: Manual control loading mediation ads requires manual preparation of advertising content for display. Use ad loading methods before trying to show: MediationManager.loadInterstitial(), MediationManager.loadRewarded(), CASBannerView.loadBanner().
