Unlike standard Banner creatives, Native Banner creatives contain separate image and text assets. The Publisher assembles these assets according to the design and layout of its site or application. Native creatives use image ratios, not fixed ad sizes. The publisher's Native protocol implementation determines placement. *** ## Creating a Native Banner Creative {% stepper %} {% step %} ### Open the Creative Creation Form Access the Creative Library from either: * **Advertisers Module > Creatives**, or * The Advertiser’s **Creatives** tab. Click **New Creative**. {% endstep %} {% step %} ### Select the Media Type In the **Media Type** field, select **Native**. The **Native Asset Input Form** is displayed. {% endstep %} {% step %} ### Enable **Run Native in Banner Spot** By default, **Run Native in Banner Spot** is enabled. It lets Native creatives deliver on standard banner ad units. Native Studio automatically generates banners for standard banner inventory. Select an **Ad Size** filter that matches your image's aspect ratio for the banner placements when the switch is ***Active***. {% endstep %} {% step %} ### Add the Native Assets Complete the required text fields and upload the applicable image assets according to the specifications below. {% endstep %} {% step %} ### Select a Styling Preset Modify the Native ad's appearance by picking an alternate styling preset, which controls its fonts, colors, and visual presentation. {% endstep %} {% step %} ### Save the Creative Review the entered information and click **Save**. You can't save the creative if a required field is missing or an uploaded image doesn't meet the validation requirements. {% endstep %} {% endstepper %} *** ## Asset Specifications | **Field** | **Required** | **Specifications** | | ------------------ | ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Title | Yes | Maximum 25 characters. | | Advertiser Name | Yes | Maximum 25 characters. | | Main Image | Yes | Supported formats: PNG, JPG, JPEG, and GIF. Maximum file size: 5 MB. Minimum resolution: 200 × 200 pixels. Supported aspect ratios: 1.91:1 example 1200x628 px, 1:1 example 1200x1200 px, 4:5 example 1080x1350 px, 4:3 example 1200x900 px. | | CTA Text | Yes | Maximum 15 characters. The default value is **Learn More**. Examples include Install and Visit. | | Logo / Icon | No | Supported formats: PNG, JPG, JPEG, and GIF. Maximum file size: 5 MB. Minimum resolution: 128 × 128 pixels. Required aspect ratio: 1:1. | | Body / Description | Yes | Maximum 90 characters. | | Privacy URL | No | Optional: Link to privacy policy or targeting information page | *** ## Main Image When you upload an image that matches any ratio listed in the asset specifications, a prompt will offer to automatically generate the remaining ratios. You can accept the automatic generation or upload each ratio manually, with the option to replace auto-generated images at any time. To ensure broad compatibility across various SSPs and publisher sites, provide as many aspect ratios as possible. The system automatically selects the optimal ratio in real time based on the incoming Native request. *** ## Styling Once you enter the text assets and upload the main image for your native creative, you can apply a styling preset. Selecting a preset updates the visual formatting, including fonts and color schemes, while providing a live preview of the native ad for each style. *** ## Asset Validation The platform validates the creative’s required fields and image assets. The creative cannot be saved when: * A required field is empty. * The Main Image does not use a supported aspect ratio. * The Logo or Icon does not use a 1:1 aspect ratio. * An image does not meet the minimum resolution. * An image exceeds the maximum file size. * An unsupported image format is uploaded. * A text field exceeds its character limit. When an image fails validation, an error message is displayed. *** ## Previewing the Creative After uploading the assets, use the **Generic Preview** to confirm that the following elements were loaded correctly: * Title. * Body or Description. * Main Image. * Logo or Icon. {% hint style="info" %} **Important:** The Generic Preview is a representative wireframe. The final appearance of the ad varies by Publisher site or application because the Publisher determines the layout and styling. {% endhint %} When the **Run Native in Banner Spot** setting is enabled, select the appropriate banner sizes in the ad size filter section. This allows you to generate and preview banner ad variations based on your Native creative for each selected size. *** ## Technical Details ### OpenRTB Mapping Native Banner creatives are mapped to OpenRTB 2.x Native standards. For example: * The Headline is mapped to the Native title asset. * The Body is mapped to the Native data/desc asset. *** ## Related articles * [How to create a Creative](/gamoshi-wiki/how-to-guides/how-to-create-a-creative.md) * [How to Implement Third-Party Pixel Tracking](/gamoshi-wiki/how-to-guides/how-to-implement-third-party-pixel-tracking.md) * [How to Implement Conversion Tracking](/gamoshi-wiki/how-to-guides/how-to-implement-conversion-tracking.md) * [How to Set Up Postback Conversion Tracking](/gamoshi-wiki/how-to-guides/postback-conversion-tracking.md) * [Gamoshi Open RTB Specification](/gamoshi-wiki/general-information/gamoshi-open-rtb-specification.md)
