Google is offering a $25 million coupon to people who can post the URL of a Google ad and get a link to the coupon.
The promo will go live at 11:59 p.m.
ET Monday, according to the Google AdWords site.
It’s not clear how long the promo will be available, but it’s the third time Google has offered a coupon in recent years.
Google previously offered a $100,000 Google ad-sales promotion that was limited to a single company.
The $25m offer comes just days after Google’s search giant announced it was cutting its search advertising by 30% this year.
The company’s stock fell more than 8% on Monday, closing at $30.43.
