“Google is rolling out a two-week experiment that will allow advertisers to promote special marketing deals in Black Friday and Cyber Monday ads using Promotion Extensions, which rolled out last year,” MediaPost reports.

“Promotion Extensions show special offers as an extension to the main ad, without needing to create new ads,” the story reports. “For example, Williams Sonoma can use Promotion Extensions to display a ‘30% Off’ promo code or ‘$20 Discount’ on all orders.”

The experiment launched Nov. 14 and runs through Nov. 27.

“The ad will appear at the top of the search results and will be part of the ads that have Promotion Extensions,” MediaPost notes, adding: “Last year, 100% of searches for Black Friday occurred between Nov. 19 and Nov. 25. The days leading up to Thanksgiving Day are the most important to get the deals in front of consumers.”
