How does Viewability Tools work?

  1. First, you choose which viewability-boosting features you want to enable at the Domain level:

    1. Lazy Loading (deterring sending ad requests to ad units).
    2. Scroll Slowing (gently & gradually decreasing scroll speed when an ad is in view but not counted as viewable yet).
    3. Ad holding “Sticking” the ad unit to the top of the screen briefly when the user scrolls down the page.

    Optionally, you can customize their parameters - how exactly they work.

  2. Then, for each Ad Unit, you decide if particular features are:

    1. Always enabled
    2. Always disabled
    3. Automatically controlled (enabled on selected pageviews only)

  3. If you enabled Automatic Control, the features are triggered based on the following logic:

    1. To reach a viewability level as close as possible to the target (default: 75%)
    2. To avoid using Lazy Loading when not necessary, as it may reduce the total number of ad requests
    3. AI-based predictions determine how often to trigger each feature, calculated independently for each Ad Unit and updated daily
