Bing Ads announced the addition of price extensions on Wednesday for mobile and desktop. The ads appear at the top of the page in search results, and descriptions allow advertisers to add content around the price for products or services.

Joseph Damiani, program manager at Microsoft Bing Ads, wrote in a post that prices used in Price Extensions must be available and visible on the landing page, and that Bing will change advertisers the same cost per click (CPC) as clicks on the ad headline.

Price Extensions also can link to a preferred third-party retailer such as Amazon or Walmart, and they serve on all devices, along with other ad extensions, including Sitelinks.

“Description cannot be duplicated in the header. For example, ’Women’s haircut’ cannot be used for both the header and the description,” Damiani wrote.

The feature is now available in the United States and will begin to roll out internationally, excluding China, Hong Kong, and Taiwan, in April.

The extension supports a variety of languages, currencies, and options to help advertisers quantify their product prices or units of service.
