While @CMIContent and @MarketingProfs found that B2C (business-to-consumer) marketers are getting more effective at using content marketing, these marketers are struggling to measure content marketing efforts. Only 23% claimed to be successful at determining ROI (return on investment), 32% unsuccessful, and more than 20% aren’t even trying to track ROI. 51% of respondents actually said that measuring content effectiveness was the top content marketing challenge, similar to @forrester’s findings that 52% of digital marketers said measuring ROI is a “hurdle to content marketing”.  - Link
