Microsoft and Google, along with many partners, are working to perfect a consumer tracking and analysis system so they can better figure out who gets to share in the growing online ad revenue pie. It’s called “engagement mapping.” Although if you are concerned about privacy, you might want to say, “let’s call the whole thing off.” Here’s an excerpt from the April 14, 2008 Ad Age article:
“The concept appears simple, but the technology is complex: raw log-file data, time-stamped and collected by ad-serving companies like Google’s DoubleClick and Microsoft’s Atlas, along with a short line of code known as a pixel hidden in web pages, keep a record of each time consumers enter or exit a web page, click on a link or ad and enter information in a search box or application. Those data are fed into software platforms designed by companies such as Atlas, Epic Advertising, Media Contacts and Starcom.
“It’s sort of like reading an advertising diary,” said Ben Winkler, VP-interactive media director at New York-based Ingenuity Media Group, which joined Atlas’ project earlier this year. “It’s like you opened a diary where someone wrote, ‘I saw three billboards, I heard a radio ad, saw a few banners ads, and searched through Google to find and buy the product.’ “
Rather than wait for a crisis to tell the advertising client something isn’t working, media buyers can rely on these data to identify when consumers had contact with the ads, even if it’s an hour, day or week later.
“We know the person saw ad No. 4 on Yahoo Finance an hour ago,” said David L. Smith, CEO at Mediasmith, which is participating in Atlas’ and DoubleClick’s tests with advertisers. “Embedded code in the pixels lets us track the pages and things they interact with on the site.”
