Target me with your ads, please reporter asks an ad company to tailor ads to her Web surfing habits. Some of it made sense, but why do they think she's into heavy construction?

I've made myself a target.

For online advertisements, that is. I know it's happening to me already, every day as I surf the Web. But because I tend to ignore the ads, I hadn't taken much note of any blatant targeting based on who I am, what I'm interested in, or my actions on the Web.

(I have noticed some pretty crazy ads in my Gmail account that made me laugh. But those are based on the context of content of the e-mail, like search ads are, and thus are not behaviorally targeted.)

The issue is on people's minds lately as technologies enable more and more monitoring of our actions on the Web and advertising gets increasingly sophisticated. Behavioral targeting was the subject of a sponsored by the U.S. Federal Trade Commission. The FTC is looking into Google's proposed acquisition of online ad serving and ad exchange provider DoubleClick, which poses privacy concerns for some and anticompetition issues for others.

The proposed Google-DoubleClick merger is just one in a recent consolidation wave that includes Microsoft's purchase of ad serving firm Aquantive and , as well as AOL buying behavioral targeting firm Tacoda and Yahoo buying online ad auction network RightMedia and BlueLithium, an online advertising network. Behavioral marketing is also spreading to social networks, including the popular Facebook, which recently announced a new ad system that has members up in arms.

During a recent briefing with online ad network Specific Media, I asked (well, really I begged) to be targeted firsthand in a live demonstration. Specific Media Chief Executive Tim Vanderhook indulged me, but I have to report that I was underwhelmed with the results. Not because the advertising wasn't targeted, but because it just didn't offend or annoy me enough. But maybe my expectations were too high.

Vanderhook showed me my profile, actually the profile of my computer, which has cookies dropped from the Web sites of Specific Media partners. It was a list of categories and subcategories based on my Web surfing habits. It showed that I was interested in things pertaining to technology and specifically the Internet and digital cameras, news and media, advertising, arts in general, cultural development, philosophy and, this is odd, heavy construction. I must have hit on some housing or building site to trigger that one.

To show how the profiling gets updated, I visited one of the 1.5 million Web sites in Specific Media's data network, a site on personal finance, and clicked on an article about debt reduction. When I went back to look at my demographic profile, a new business category had been added: "macro economics:credit and debt."

Fitting the profile?
Specific Media also predicts my age, gender, race, and income based on the Web sites I visit. So, at work, I'm probably a middle-age white man who reads a lot of tech news sites. At home, I expect I'm a young to middle-age white woman who visits a lot of entertainment and animal- and environment-related sites. But either way, they don't know exactly who I am, where I live, or how to reach me.

I then tested how the system targets me with ads based on what sites I visit. I went to a portal for a broadband Internet service provider that Vanderhook asked me not to identify. At the top of the page it served me an ad for a debt reduction company and at the bottom an ad for a credit card company.

What if I were visiting Web sites related to something that could be highly personal or embarrassing if other people knew it was targeted at me, like sexual dysfunction, pregnancy, or even bad breath?

Specific Media doesn't serve ads for sensitive categories including certain health conditions, like AIDS or sexual dysfunction, but ads targeted at pregnant women aren't necessarily excluded, Vanderhook said. And halitosis? Apparently, there isn't much brand advertiser interest in that category yet.

In addition to online ad networks, search sites like Yahoo, Google, and Microsoft are amassing a heavy arsenal of targeted advertising capabilities. Yahoo has been doing behavioral targeting for more than six years, "longer than anybody," said Richard Frankel, senior director of product marketing at Yahoo.

Yahoo not only has a portal that attracts millions of visitors every day, but the company also knows what searches are conducted and knows who you are based on your Yahoo account registration for things like Yahoo Mail.

Yahoo's behavioral targeting is based on visits to pages on the Yahoo network and partner sites like eBay, Comcast, and, what searches on Yahoo you have conducted, and which ads you clicked on and viewed. If you are logged in to your Yahoo account, the site can target you based on your age and gender, but that targeting system is separate from the behavioral targeting system, Frankel said.

I thought I'd give Yahoo's behavioral ad targeting system a whirl. I conducted searches for "Toyota RAV 4," "autos," and "Jetta" and clicked on some results. Then I went into my Yahoo Mail and, sure enough, there was an ad for Buick. The system obviously wasn't picking up that I was interested in foreign makes.

"We can't read your mind," Frankel said in response. "I don't know that you would never consider a domestic car. (Domestic car makers) want to compete for that business too."
