Explain how to use ad customizers with audience exclusions in Bing Ads.

To use ad customizers with audience exclusions 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 audience exclusions, you might include a column for the audience you want to exclude.

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 audience exclusions, you can use the {if} placeholder to insert custom text only for users who are not in the excluded audience. For example, your ad template might look something like this: "Shop our {if audience:excluded_audience}non-{/if}sale items now!"

4. Set up audience exclusions: To set up audience exclusions, navigate to the "Audiences" tab in your Bing Ads account and click on the "Exclusions" button. From there, you can create a new audience exclusion and select the audience you want to exclude.

5. Apply the audience exclusion to your ad group: Once you have set up your audience exclusion, you need to apply it to the ad group where you are using ad customizers. To do this, navigate to the "Settings" tab in your ad group and scroll down to the "Audiences" section. From there, you can select the audience exclusion you created in step 4.

6. Preview and test your ads: Before launching your ads, be sure to preview and test them to make sure they're displaying the correct information for the excluded audience. You can use Bing Ads' ad preview tool to see how your ads will appear to users in and not in the excluded audience.

Overall, using ad customizers with audience exclusions in Bing Ads can help you create more targeted and relevant 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.
