How do you set up default text for ad customizers in Bing Ads?

Setting up default text for ad customizers in Bing Ads involves using parameters that ensure your ads display meaningful information even when specific data isn't available or applicable. Here's how you can set up default text for ad customizers:

1. **Understand Ad Customizers**: Ad customizers in Bing Ads allow you to dynamically insert text into your ads based on parameters such as countdowns, price, promotions, or other variables. Default text ensures that if specific data isn't available (e.g., due to errors or missing information), a fallback option is used.

2. **Use Default Values in Customizer Feeds**: When setting up ad customizers, you typically create customizer feeds that contain variables and associated default text. For example, if you're using a price customizer, you might set a default price to display if the actual price isn't available.

3. **Insert Parameters in Ad Copy**: Implement ad customizers directly into your ad copy using Bing Ads' syntax for placeholders. For instance, `{=FeedName.AttributeName:DefaultText}` is used to insert data from your feed, with `DefaultText` being the fallback option.

4. **Handle Errors and Unavailable Data**: Ensure your default text is meaningful and compliant with Bing Ads policies. If data for a specific ad customizer attribute isn't available or fails to load, Bing Ads will automatically substitute it with the default text you've defined.

5. **Testing and Verification**: Before launching your ad campaigns, thoroughly test ad customizers to verify that default text displays correctly when needed. Test scenarios where specific data might not be available to ensure your fallback options are functioning as expected.

6. **Regular Monitoring and Updates**: Monitor the performance of your ads that utilize ad customizers to ensure default text is used appropriately and adjust as needed based on feedback and data analysis. Regularly update default text to align with changes in pricing, promotions, or other variables.

Here's an example of how you might set up default text for a price ad customizer in Bing Ads:

```plaintext
{=PriceFeed.Price:DefaultPrice}
```

In this example:
- `{=PriceFeed.Price}` specifies that the ad customizer should insert the price from the "PriceFeed" feed.
- `DefaultPrice` is the default text that will appear if the price data isn't available or fails to load.

By setting up default text effectively, you ensure your ads remain relevant and informative to users, even under varying circumstances where specific data may not be immediately accessible. This practice helps maintain ad consistency and enhances the overall user experience in Bing Ads campaigns.
