ROI on the different media landscapes
Whilst there exist various mediums for marketing and communication eg radio, TV, social media etc. How can we effectively measure the success of these campaigns? I know this has possibly been discussed for years but really, beyond impressions, reach, GRPs, views how can we measure the success of a campaign and how does that success tie in with direct sales? The costs of the campaigns are often quite high- are these measures (reach , impressions, GRP's) enough to justify ROI?
