SearchIgnite, which spends about $200 million each year on search advertising, says that clicks on Google ads aren't down or even flat as ComScore recently claimed. They're up 40.1 percent year-over-year. On all major search engines, paid clicks are up 45.7 percent year-over-year — up 65 percent for retailers and non-mortage-related financial services. So WTF, ComScore? The most likely answer: ComScore has surveys; SearchIgnite has invoices. (Photo by bitzcelt)
