As the U.S. moves into a possible economic slowdown, partially caused by the subprime mortgage meltdown, the question is whether the pain will spread to online advertising. Online ads have been booming since the dot-com bust ended around 2003, with 20%+ growth every year. When recession questions arose recently, many analysts believed online advertising would remain “recession-proof” because it’s relatively cheap compared to TV or newspaper ads, and because it’s easier to track. The king of paid-search ads, Google, offered a similar rationale for why it would weather an economic storm, but now comScore found that clicks on Google ads have dropped the past two months. Google’s once high-flying stock has been hammered, from a high last November of $740 to around $470 today. Do you think online advertising and/or Google would get hit by a recession or will it survive a larger economic hit? Do you find yourself clicking on less Google ads and buying less online?
