Last week I tried to get all literary in my approach to the cookie deletion problem that's been irking behavioral marketers and other online ad folk. But there's no need to liken cookies and privacy infringement to homeland security issues, or anything else for that matter. A very real example of how one company's potential cookie nightmare could be used to its benefit -- and perhaps the benefit of all companies relying on the legitimate use of cookies -- exists today.

Last week I took the PATH train from Jersey City to lower Manhattan on my way to catch my favorite Brooklyn band. On the heels of the London attacks, the threat of terrorism on that train or near my neighborhood has nestled itself in the front of my mind once again after years of slowly regressing. And the tradeoffs between civil liberty-squelching security strategies and protection against further strikes are all too real. Sure, I resent the fact that heightened security robs me of civil liberties. But I'll tell you this much, when I saw four cops in my …

From communism to market-timed stock trading, most theories look good on paper, but are destined for failure in practice. Why? They fail to consider the fact that emotional, irrational -- and just plain unpredictable -- humans will be the ones carrying those theories out. Well, this may come as a shocker, but the folks on the receiving end of behaviorally-targeted (BT) ads ain't robots, either.

I'll admit it: I'm not much of a Behavioral Insider. Behavioral Observer might be a better description. There's an anthropological connotation to the label that I suppose is fitting for a journalist type such as myself charged with commenting on an industry I've only viewed as an onlooker rather than an insider. Yet, despite my lack of insider experience, I've always felt qualified to opine about advertising and marketing. After all, I've been targeted by it my entire life.

When eBay acquired Shopping.com for $620 million last month, I'm sure more than a few people had flashbacks to the pre-bubble Internet glory days. I, however, had a slightly different reaction. I think that eBay and other stalwart Internet companies are in line with the old adage that if you solve people's problems then you have a good chance of success. In fact, I think that the Shopping.com solution is instructive for the behavioral targeting industry as we confront many of those same challenges.

Working for a relationship marketing agency, I am always amazed when I meet with new clients who have complex funnels of customer engagement. Even more amazing to me, is when asked what they do at the end of each funnel they say, "Aha, that's where we hit them with the ad to buy the 8780!" I have news for you. If all your responses are the same regardless of what data you gather on the customer, then all you have constructed is an elaborate monologue. What you want to do instead, is change your message to match the behavior. Imagine …

Roger Federer steps up to the baseline. He checks the ball in his hand, bounces it... once, twice, three times in his preserve routine. He brings the ball to the racket face and then tosses it up into the air... the serve screams over the net and nicks the tape. Ace. Most of us can only dream of achieving this level of tennis acumen. For most of us, our day jobs relegate us to spectators or - at best - weekend warriors. However, even if you don't have Wimbledon aspirations, once you know the rudiments of the game and …

It's hard to make sense of today's crowded targeting landscape. With nearly 100 self-proclaimed ad networks and targeting providers to choose from, how can an advertiser possibly choose the right solution without investing months in due diligence? Most networks offer fundamentally different targeting services: many group placements into interest categories (e.g. sports, weather, etc.), Google facilitates contextually relevant placements on specific sites, AlmondNet utilizes past search behavior, Revenue Science offers publisher surfing profiles, Yahoo! has strong geotargeting capabilities fueled by their registration information, Claria targets off information passed back through their desktop application, and Advertising.com uses action tags.

Whoever said, "I know half of my advertising works, I just don't know which half," did not know at the time where Internet advertising would be today and where TV advertising will be tomorrow. Putting the hot cookie deletion issue aside for a moment, our ability to track from investment to fulfillment with online media is superb, at least in comparison to traditional media.

Two perceptions many advertisers have are: "Behavioral marketing is something you only buy from a publisher or ad network." Behavior is a "hands-off" observation like a science experiment in a glass case.
