NEW YORK A New York firm today announced a free site that lets consumers and marketers search brand activity on Twitter.

The site, Trackingtwitter.com from ElectricArtists, aims to be a directory for Twitter feeds. Previously, users had to search Twitter and compile the feeds themselves.

Among the brands being tracked so far are Twitter-friendly entities like Zappos, Whole Foods, JetBlue and Starbucks, none of which are ElectricArtists clients, though the agency also provides the service for clients like A&E and the History Channel.

"For a lot of clients we've been looking to build a strategy on Twitter," said Marc Schiller, shop CEO. "In doing that, we're always asking the questions 'Who has been using Twitter most effectively?' and 'Who's feeds should I follow?' and so we built a tool for our staff to follow Twitter feeds in different categories. So what we decided to do is just make it public because Twitter doesn't really have a good directory."

The effort comes as Twitter recently secured $35 million in financing from various venture capital firms. Todd Dagres, founder of one of the VC firms, Spark Capital, recently told blog Innovation Economy, "We know how we're going to do it, and we're very confident about how we're going to do it, and it's not necessarily in our interest to tell people how we're going to do it. There is a biz model that has yet to be implemented. Of course, I can't guarantee it's going to work."
