One of the latest automated ad extensions tested by Microsoft Advertising is a “Made in USA” label, accompanied by a flag icon.
The automated ad extension was seen in Bing.com results in Germany by Frank Sandtmass of Hamburg-based SEO and Analytics firm Vertriebsberatung.
The purpose of these automated ad extensions is to give users more information and increase click through rates. These extensions pull data from a range of different sources, such as landing pages and domains, ad copy and in some cases third-parties. They can be displayed automatically without advertiser opt-in.
It’s not known how widespread this test is, as I haven’t been able to replicate the extensions myself. Microsoft Advertising hasn’t commented as of this writing on the details.
