JPMorgan Chase this week announced a partnership with Twitter that will award some of the New York bank's more than four million small business customers with free credits to advertise on the social media site.

Twitter will give Chase's small business customers more than $1 million in free Twitter advertising credits. In a blog post published by Twitter Monday, the company said credits for Twitter's small business advertising platform will be awarded to customers in $100 increments. More details about the perk will become available this fall.

"Our goal is to help small businesses build better customer engagement, increase sales using direct response techniques, and engage more followers with compelling content. We'll be posting videos, infographics, white papers and a how-to guide developed by Chase and Twitter to help small businesses learn more about the value of Twitter," wrote Twitter's Russ Laraway in a post.

The alliance also includes sharing best practices content through the @ChaseSmallBiz Twitter handle as well as hosting live workshops meant to help small businesses learn how to use Twitter.

Twitter similarly partnered with American Express in February 2012. Some Amex cardmembers and merchants were awarded with free Twitter advertising.
