Explain how to use ad customizers with Bing Shopping campaigns.

Ad customizers can be used with Bing Shopping campaigns to create dynamic product ads that include personalized information such as pricing, availability, and promotions. Here's how to use ad customizers with Bing Shopping campaigns:

1. Create a data feed: The first step is to create a data feed that contains the information you want to include in your product ads. The data feed should be a CSV or XML file that includes columns for each piece of information you want to include. For example, you might have columns for "product name", "price", "availability", and "promotion text".

2. Create a Shopping campaign: Next, create a Shopping campaign in Bing Ads and create a product group within that campaign.

3. Create a dynamic ad template: In the product group, create a dynamic ad template that includes the ad customizer code. The ad customizer code is a placeholder that will be replaced with the actual information from your data feed. For example, your ad copy might include the following code: "{=ProductName}: {=Price} - {=Availability} - {=PromotionText}", where "ProductName", "Price", "Availability", and "PromotionText" are the names of the columns in your data feed that contain the product name, price, availability, and promotion text, respectively.

4. Upload your data feed: Once you have created your dynamic ad template, upload your data feed to Bing Ads. You can do this by going to the "Catalogs" section of Bing Ads and clicking on "Product Feeds". From there, you can upload your data feed and map the columns to the appropriate ad customizer fields.

5. Set up ad rotation: To ensure that your product ads with ad customizers are shown to the right audience, set up ad rotation in Bing Ads. This will allow you to show different ads to different users based on the information in your data feed.

6. Monitor and optimize: Once your product ads are up and running, monitor their performance and optimize as needed. You can use Bing Ads' reporting tools to see which ads are performing well and which ones need to be tweaked.

Here's an example of what the ad copy might look like with ad customizers in a Bing Shopping campaign:

Headline: {=ProductName}
Description: Get {=ProductName} for {=Price}. {=Availability}. {=PromotionText}.

In this example, {=ProductName}, {=Price}, {=Availability}, and {=PromotionText} are all ad customizer fields that will be replaced with information from your data feed. By using ad customizers, you can create dynamic product ads that are more targeted and relevant to your audience.

For example, if your data feed includes a product with a price of $100, availability of "In stock", and a promotion text of "Free shipping", the ad copy might look like this:

Headline: Acme Widget
Description: Get Acme Widget for $100. In stock. Free shipping.

By using ad customizers with Bing Shopping campaigns, you can create dynamic product ads that are more likely to convert and drive sales.
