{% note info %}

Keep in mind that blocks can reduce the number of ads available for impressions and, therefore, decrease your revenue.

{% endnote %}


## Block by domain or Bundle ID {#domain-bundle}

1. Open the app page in the Boost interface, click **Ad Monetization**, and go to **Blockings**.
1. Add the domains or Bundle IDs of apps that you don't want to see advertized in the app. You can add several comma-separated blocks at once.
1. Click **Add**.

All changes to settings will automatically take effect 30 minutes after saving them.
To cancel a blocking, find it in the list of blockings below and delete it using the ![](../../_images/common/delete.png) element (that appears on hover).
To remove all units, click **Clear list**.

You can also block the display of unwanted ads for all applications in your account. For more information, see [Account registration and setup](https://boost.yandex.com/doc/en/ad-monetization/monetization/account/block.md).

## Block by category {#setting-thm}

You can restrict displaying ads on certain categories:

1. Open the app page and click **Ad Monetization**.
1. Go to the **Blockings** → **Add blocking** → **Topics** tab and select the categories you want to block from the list.
1. Click **Add**.


These restrictions will apply to all ad units in the app.
If you can't find the category you're looking for, contact support.
