Dive Brief: 

• In a push to attract advertisers for the holiday season, Twitter is giving away up to $1 million in free advertising. 
• The campaign, meant to celebrate Small Business Saturday, will offer $100 credits to small businesses that register. 
• The credits can be used for Promoted Tweets or Promoted Accounts for businesses with a U.S. address who have not registered before. 

Dive Insight: 

The move to offer free ad credits is both a push to find new advertisers and an appeal to retail shoppers by running more SMB ads. Twitter is smart to offer a small taste of what its ad products can do, and small businesses would be wise to register for the credit, as they really have nothing to lose with free advertising around the holidays.
