Pay Per Click advertisers will have to shorten their ads appearing with Yahoo Search Marketing to a paltry seventy characters before January 18th. According to an email communique sent to YSM clients "the streamlined design will make the search results displayed onn Yahoo even easier to read." The development brings some standardization to the pay per click advertising arena as it matches the shorter ads proffered by both Google Adwords and the MSN Ad Center. So in the halls of online advertising the question seems to be: can you tell your "story" in seventy characters or less?
