Success is of course a personal concept, but when running ads or promotions many people don't really understand how it works. Anything less than three or four impressions in a given placement is worthless. It takes eight to ten placements to really get any result that could be considered as representative. That means a B&W placement needs at least a year of running to show any results. Thats what any good marketing and PR person can tell you. Its cumulative, not resultant. Even more so with the photo game.
