How can you use ad customizers to highlight seasonal promotions in Bing Ads?

Using ad customizers to highlight seasonal promotions in Bing Ads allows you to dynamically update your ad content based on specific dates or events, ensuring your ads remain relevant and timely during seasonal campaigns. Here's how you can effectively use ad customizers for seasonal promotions:

### Step-by-Step Guide:

1. **Set Up Your Ad Customizer Feed:**

   - **Data Feed Creation:** Create a new ad customizer feed in Bing Ads under the Shared Library section. Prepare your feed using a .CSV or .XLSX file format.
   
   - **Include Seasonal Attributes:** Add columns in your data feed for seasonal attributes such as promotion start date, promotion end date, discount percentage, special offer details, and any other relevant information.

2. **Define Ad Customizer Parameters:**

   - **Use Parameters in Ad Text:** Write your ad copy using ad customizer parameters to dynamically insert seasonal promotion details. For example:
     - **Headline:** "Seasonal Sale - {=Feed.Discount}% Off!"
     - **Description Line 1:** "Limited Time Offer!"
     - **Description Line 2:** "Shop Now - Ends {=Feed.PromotionEndDate}!"

3. **Implement Ad Customizers in Ads:**

   - **Syntax and Formatting:** Ensure that ad customizer parameters are correctly formatted within braces { } and placed in your ad text where you want dynamic content to appear.
   
   - **Preview Ads:** Use Bing Ads' preview tool to verify how your ads will look with different data inputs from your ad customizer feed. This helps ensure accuracy and relevance.

4. **Schedule Updates and Adjustments:**

   - **Automatic Updates:** Set up schedules or rules within Bing Ads to automatically update your ad customizer feed based on seasonal changes, such as start and end dates of promotions.
   
   - **Real-Time Adjustments:** Monitor performance and adjust ad customizer details in real-time if there are changes to promotions or seasonal events.

5. **Monitor Performance and Optimize:**

   - **Performance Metrics:** Regularly monitor key metrics such as CTR, conversion rates, and ROI for ads using seasonal ad customizers.
   
   - **A/B Testing:** Conduct A/B testing with different variations of seasonal ad customizers to identify the most effective messaging and optimize accordingly.

6. **Compliance and Policy Adherence:**

   - Ensure that your ad content, including dynamically inserted seasonal promotions, complies with Bing Ads' advertising policies. Avoid misleading claims and ensure accuracy in your promotional messaging.

### Example Scenario:

Let's say you're running a seasonal promotion for winter clothing:

- **Ad Headline:** "Winter Sale - Up to {=Feed.Discount}% Off Jackets!"
- **Description Line 1:** "Stay Warm this Winter!"
- **Description Line 2:** "Shop Now - Sale Ends {=Feed.PromotionEndDate}!"

In this example, {=Feed.Discount} and {=Feed.PromotionEndDate} are dynamically populated based on the data in your ad customizer feed, reflecting current promotional details.

By following these steps, you can effectively use ad customizers in Bing Ads to highlight seasonal promotions. This approach ensures your ads are more relevant to users searching for seasonal offers, improving engagement and driving conversions during peak promotional periods.
