The study reports “
consumers who were served display ads conducted 61 percent more searches on related keywords purchased for search marketing purposes. Also, the group that was served the display ads clicked through onrelated terms at a rate 249 percent higher than consumers who were not exposed to the ads, and clicked on links leading to the testt site at a rate 139 percent higher than those not served display ads.”
So there, display ads work.
So, don’t you think that makes the folk at Google and the big portals getting 80% of this type of advertising feel good?
