Many savvy search marketers capitalized on this opportunity to communicate with concerned consumers. For the week ending April 26, Comscore observed 271 different advertisers with paid search inventory against these terms, up from just 73 the previous week and 33 the week before that. The number of clicks on paid search ads also increased considerably to 42,000 during the week ending April 26, up from fewer than 100 the previous week. With more confirmed cases of swine flu developing in the U.S. this week, consumer search and paid search activity related to the swine flu is likely to increase even more.

“This example illustrates an important opportunity for marketers to use paid search to move beyond the standard direct-response sales model,” said Eli Goodman, Comscore search evangelist. “When an international issue on the level of the swine flu pandemic presents itself, a paid search strategy enables the timely delivery of important messages to the public. Whether for public safety or to drive product sales, paid search puts the relevant information into consumers’ hands at their time of greatest need.”

Notably absent from the list of advertisers were makers of prescription drugs, who may be sitting on the sidelines due to recent FDA guidance around paid search marketing practices.
