Just how much money is there at the table in the digital "turf war" among PR, advertising and other related agencies? At the PRSA T3 Conference today in New York, Voce Communications New Media Strategist Josh Hallet said one of Voce's larger clients has an "SEO budget of $13 million a year."

The statement doesn't jive with what we've heard about SEO rates/spend, but we'll take Hallet's word for it. Branching out into measurement tools, Hallet said he uses a combination of Radian6, Nielsen BuzzMetrics, FeedBurner and TweetBurner, while also using free survey tools such as Survey Monkey to poll targeted audiences. "Can we unify this all?" Hallet asked, pointing out that there is a golden opportunity for vendors in this area to either aggregate tools or provide their own comprehensive offering.
