4 To follow users’ behaviour. Behavioural ad targetingis all about relevance – dynamically
serving relevant content, messaging or ad which matches the interests of a site visitor
according to inferences about their characteristics. These inferences are made by
anonymously tracking the different types of pages visited by a site user during a single
visit to a site or across multiple sessions. Other aspects of the environment used by
the visitor can also be determined, such as their location, browser and operating
system. For example, FT.com using software from Revenue Science can identify users
in eight segments: Business Education, Institutional Investor, Information
Technology, Luxury and Consumer, Management, Personal Finance, Travel and
Private Equity. The targeting process is shown in Figure 8.19. First the ad serving
system detects whether the visitor is in the target audience (media optimisation),
then creative optimisation occurs to serve the best ad for the viewer type.
Interactive ad formats
As well as the classic 468 60 rotating GIF banner ad which is decreasing in popularity,
media owners now provide a choice of larger, richer formats which web users are more
likely to notice. Research has shown that message association and awareness building
are much higher for flash-based ads, rich-media ads and larger-format rectangles (multi-
purpose units, MPUs) and skyscrapers. View the rich media ads at http://www.eyeblaster.com
or http://www.tangozebra.comand you will agree that they definitely can’t be ignored.
Other online ad terms you will hear include ‘interstitials’ (intermediate adverts before
another page appears); and the more common ‘overlays’ (formerly more often known as
‘superstitials’ or ‘overts’) that appear above content and of course ‘pop-up windows’ that are
now less widely used because of their intrusion. Online advertisers face a constant battle
with users who deploy pop-up blockers or less commonly ad-blocking software, but they
will persist in using rich-media formats where they generate the largest response.
