For several years, Internet advertising has been the only major media ad category to show significant growth. There are three factors driving online ad growth trends: (1) increased user time online, (2) improved measurement and accountability, and (3) targeting.
American teenagers (as well as the average British, Australian, and New Zealander Web surfer) now spend more time on the Internet than watching television.“American Teenagers Spend More Time Online Than Watching Television,” MediaWeek, June 19, 2008; A. Hendry, “Connected Aussies Spend More Time Online Than Watching TV,” Computerworld Australia, May 21, 2008; and “Brits Spend More Time Online Than Watching TV,” BigMouthMedia, July 12, 2007. They’re reading fewer print publications, and radio listening among the iPod generation is down 30 percent.M. Tobias, “Newspapers under Siege,” Philstar, May 18, 2009. So advertisers are simply following the market. Online channels also provide advertisers with a way to reach consumers at work—something that was previously much more difficult to do.
Many advertisers have also been frustrated by how difficult it’s been to gauge the effectiveness of traditional ad channels such as TV, print, and radio. This frustration is reflected in the old industry saying, “I know that half of my advertising is working—I just don’t know which half.” Well, with the Internet, now you know. While measurement technologies aren’t perfect, advertisers can now count ad impressionsEach time an ad is served to a user for viewing. (each time an ad appears on a Web site), whether or not a user clicks on an ad, and the product purchases or other Web site activity that comes from those clicks.For a more detailed overview of the limitations in online ad measurement, see L. Rao, “Guess Which Brand Is Now Worth $100 Billion?” TechCrunch, April 30, 2009. And as we’ll see, many online ad payment schemes are directly linked to ad performance.
Various technologies and techniques also make it easier for firms to target users based on how likely a person is to respond to an ad. In theory a firm can use targeting to spend marketing dollars only on those users deemed to be its best prospects. Let’s look at a few of these approaches in action.
