# Content Filters for Placements
After you complete setting up your app and placement, you can add content filters to control which offer types appear on each placement or across your entire app.
A placement represents the location of the Offer Wall within your app. You can add multiple placements within one app, providing you more control over the content shown in each DT Offer Wall Placement.
Create a category filter to prevent offers from specific categories or task types from appearing in selected DT Offer Wall placements.
## Adding Category Filters
To add a Category Filter, complete the following steps:
1. In [DT Console](https://console.fyber.com/applications), go to **Montetization→Offer Wall**.\
The **Offer Wall Publisher Dashboard** appears.
2. Click the **Content Filters** tab from the toolbar.\
The **Content Filters** window appears.
3. Click **Add Filter**.\
The **Configure Category Filter** window appears.

Adding too many category filters for your apps can decrease your revenue.
{% endhint %}
4. Select the values for the following fields in the **Target** area:
* Select an App to create a filter from the **Applications** drop-down list.
* Select a Placement from the **Placements** drop-down list.\
All of the app's Placements automatically appear in the **Placements** field. Make sure that only the placements that you want to set up this filter for are selected.
* Select one or more countries from the **Countries** drop-down list.
5. Select one or more values for the following fields in the **Blocked Category** section:
* **User tasks**
* **Ad Contents**
* **Genres**
6. Select one or more of the following options in the **Blocked Offers Complexities** dropdown list:
* **Easy**
* **Medium**
* **Hard**
7. Click **Create Filter**.\
A confirmation message appears, and the filter is immediately applied.

## Creating a Survey-Only DT Offer Wall
A common use for Content Filters is creating a Survey-Only DT Offer Wall. This configuration shows only surveys, which users can complete easily and have a higher engagement. Surveys provide feedback for advertisers and generate revenue for publishers.
To add a Survey-Only Content Filter, complete the following steps:
1. Create a new [placement](https://app.gitbook.com/s/LbREhkP3WlLtP6TNVZ2Q/offer-wall/setting-up-an-existing-app/setting-up-placements) in the Publisher Dashboard and name it `Survey`.
2. Apply content filters to block all task types except **Survey Completion** to the Placement you created.
3. Click **Save**.\
The **Survey Placement** window now shows all available survey completion offers.
