BusinessOnline, a San Diego-based digital marketing agency, announced it has acquired UpWord Search Marketing, a Boston-based digital agency specializing in search marketing, social media, content marketing and analytics.

Both agencies serve Fortune 1000 companies, including FujiFilm, Honeywell, HP, Lincoln Electric, Milgard, Pfizer, Philips, Teradata, and others.

“We have been championing performance-driven digital marketing and delivering results for more than 17 years,” BusinessOnline CEO Thad Kahlow said in a press release. “This acquisition is a natural progression of our leadership as we continue to create greater expertise in search, content and data to improve our clients’ marketing return on investment in a business environment that is increasingly demanding and competitive. Having an East Coast office allows us to provide our proven, data-driven strategies to businesses across the country.”

Serving as the East Coast office of BusinessOnline, UpWord will operate out of its current Boston office under the leadership of Brian Silver and Robert Cavilla.

In addition to the acquisition of UpWord, BusinessOnline also recently launched Data Weld, a sister company focused on delivering outsourced marketing analytics and insights that help to prove and improve marketing’s impact on business.
