What are the different types of ad extensions available in Bing Ads?

As of my knowledge up to 2021, Bing Ads offers the following types of ad extensions:

1. Sitelink Extensions: These allow you to add additional links to your ad, pointing to specific pages on your website.

2. Location Extensions: These display your business address, phone number, and a map marker with your ad. They can help drive foot traffic to your physical location.

3. Call Extensions: These allow you to add a clickable phone number to your ad, enabling users to call your business directly from the search results page.

4. Callout Extensions: These are additional text options that allow you to highlight unique selling points or additional benefits of your business, products, or services.

5. Structured Snippet Extensions: These allow you to highlight specific aspects of your products or services by using predefined headers, such as "Brands," "Destinations," "Models," or "Types."

6. Price Extensions: These display pricing information for your products or services directly within your ad. They can help attract more qualified clicks from users who are ready to make a purchase.

7. Action Extensions: These allow you to add a call-to-action button, such as "Apply now," "Book now," or "Download," to your ad.

8. Image Extensions: These allow you to add relevant images to your search ads, helping them stand out in the search results and potentially increasing click-through rates.

9. Dynamic Sitelink Extensions: These automatically generate additional links based on the content of your landing page, helping to promote relevant content to users.

10. Dynamic Call Extensions: These automatically generate call extensions using phone numbers found on your website.

11. Dynamic Image Extensions: These automatically generate image extensions using images found on your website.
