How do you create ads with dynamic URL parameters using ad customizers in Bing Ads?

To create ads with dynamic URL parameters using ad customizers in Bing Ads, you can follow these steps:

1. Create a customizer feed: A customizer feed is a data file that contains the information you want to insert into your ads. This can include things like promotional text, product prices, and images. For dynamic URL parameters, you might include a column for the specific URL parameter you want to insert.

2. Set up ad customizers in your ad groups: Once you have created your customizer feed, you can set up ad customizers in your ad groups. To do this, navigate to the "Ads" tab in your Bing Ads account and click on the "Ad customizers" button. From there, you can create a new ad customizer and select the feed you created in step 1.

3. Create ad templates: Ad templates allow you to specify how the custom text will be inserted into your ads. For dynamic URL parameters, you can use the {param:customparameter} placeholder to insert the custom parameter from your feed. For example, your ad template might look something like this: "Visit our website and check out our {param:product_category} selection!"

4. Map your custom parameter to the URL: In order for the dynamic URL parameter to work, you need to map the custom parameter to the URL in your ad. To do this, click on the "URL options" button when creating or editing your ad. From there, you can select the custom parameter you want to use and map it to the appropriate URL field (e.g. the "Final URL" or "Tracking template" field).

5. Preview and test your ads: Before launching your ads, be sure to preview and test them to make sure the dynamic URL parameters are working correctly. You can use Bing Ads' ad preview tool to see how your ads will appear to users, and click on the ads to make sure they're directing to the correct URL with the dynamic parameter included.

Overall, using ad customizers to create ads with dynamic URL parameters in Bing Ads can help you create more relevant and personalized ads for your users. Just be sure to follow best practices for creating and managing your customizer feeds and ad templates, and test your ads thoroughly before launching.
