75% of marketing and ad campaigns in 2014 failed to meet management's expectations. Recent research by The Fournaise Marketing Group measured the effectiveness of more than 2.5 million B2C and B2B marketing strategies, campaigns and ads across all media channels (traditional, digital, direct, mobile), throughout more than 20 countries. The study identified what worked, what did not, where, when and why to help advise marketers on what needs to be done to deliver better results, performance and ROI. Marketers made three critical effectiveness mistakes in 2014, according to the study: weak and unattractive customer value propositions (CVPs), underperforming creative executions and incorrect and/or incomplete data.
