Why do ad designers sometimes seem to lack common sense? I’ve seen three billboards with web site advertisements which do not have the URL prominently displayed. The URLs are in a smaller font, don’t catch your eye, and are overshadowed by the large message that the ad tries to get across. The Northern Light billboard which loudly proclaims “SEARCH THE WEB” has the URL stuck in the bottom right corner. OK, it’s true that many people get stuck in traffic here with ample time to digest the contents of all the billboards, but it seems that the “takeaway” for a web site ad has got to be the URL. It’s useless otherwise.
