San Diego-based CPC Strategy, an internet marketing company, has been acquired by New York-based digital marketing agency Elite SEM. CPC is known best for its work with Amazon, according to a press release.

Terms of the deal were not disclosed. Rick Backus, CEO of CPC Strategy, and other members of the leadership team will continue in their posts. The combined entity will be one of the largest independent performance marketing agencies in the United States managing close to $1 billion in digital media spending a year, said Nii Ahene, CPC chief’s operating officer.

With over 125 employees, CPC Strategy works with companies like The Honest Company, Hallmark, Nestle, Unilever's Seventh Generation and others. Among other responsibilities, CPC handles media planning and placement, content services and analytics.

"The acquisition of CPC Strategy is our response to the escalating demand from Elite's most successful clients for strategy and execution in the Amazon marketplace, including its media offerings, creative services, and analytics, and the integration of Amazon with other performance media channels," said Zach Morrison, president of Elite SEM.

The CPC acquisition is Elite SEM's third acquisition since partnering with Denver-based private equity firm Mountaingate Capital in February 2017 following the purchase of Paid Social media agency OrionCKB in November 2017 and email and customer relationship management specialist shop Email Aptitude in May.
