What are the prerequisites for using ad customizers in Bing Ads?

To effectively use ad customizers in Bing Ads, there are several prerequisites that advertisers need to fulfill. These prerequisites ensure that ad customizers function correctly and comply with Bing Ads' policies. Here are the key prerequisites:

1. **Microsoft Advertising Account**:
   - You need to have a valid Microsoft Advertising (formerly Bing Ads) account. If you don't have an account yet, you'll need to sign up and create one.

2. **Shared Library Access**:
   - Ad customizers are managed within the Shared Library section of Bing Ads. Ensure that you have access to the Shared Library in your Microsoft Advertising account.

3. **Data Feed or Business Data Source**:
   - Ad customizers in Bing Ads require a structured data feed, often referred to as a Business Data feed. This feed contains the dynamic content that will be inserted into your ads.
   - Prepare your data feed in a .CSV or .XLSX file format with columns for different attributes (e.g., product names, prices, promotions, countdowns).

4. **Data Feed Requirements**:
   - The data feed must comply with Bing Ads' specifications and guidelines. This includes formatting requirements, such as column headers and data types, to ensure accurate data insertion into ad customizers.

5. **Understanding of Ad Customizer Syntax**:
   - Familiarize yourself with the syntax and formatting rules for ad customizers in Bing Ads. Parameters in ad customizers are enclosed within braces { } and must be correctly implemented to function properly.

6. **Testing and Validation**:
   - Before launching campaigns with ad customizers, it's essential to test your setup using Bing Ads' preview tool. This tool allows you to see how ad customizers will display in your ads and ensure they are working as intended.

7. **Compliance with Policies**:
   - Ad customizers must comply with Microsoft Advertising policies. Ensure that your ad content, including dynamically inserted data, meets Bing Ads' guidelines on accuracy, relevance, and transparency.

8. **Campaign Setup**:
   - Set up campaigns or ad groups where you plan to use ad customizers. Ad customizers can be applied at the ad group level, allowing you to tailor messages based on specific targeting criteria or themes.

9. **Regular Maintenance and Updates**:
   - Plan for regular updates to your data feed to keep ad customizers current and relevant. This includes scheduling updates for pricing changes, promotions, inventory updates, etc.

By meeting these prerequisites, advertisers can effectively leverage ad customizers in Bing Ads to create more dynamic and personalized ad experiences for their audiences. Ad customizers enhance ad relevance, improve engagement, and allow for efficient management of ad content across campaigns.
