Vantage Media, an El Segundo provider of performance marketing and online advertising services, on Monday said that it has merged with BrokersWeb, a Miami provider of pay-per-click advertising.

Vantage Media said the merger would create one of the world’s largest online performance marketing companies and accelerate its vertical expansion efforts. Financial terms were not disclosed. Both companies are privately held.

“The transaction allows both companies to build upon and leverage the strengths of each other,” said Vantage Media Chief Executive Patrick Quigley, who will lead the combined companies under the Vantage Media name. “Our technology platforms and media capabilities are highly complementary and the combination will create immediate revenue opportunities and additional value for our clients and media partners.”

The BrokersWeb business will retain the “BrokersWeb” name and all of its management, he said in a statement.
