Here’s a thought – marketing is not just about numbers it is about understanding human behaviour. For example, if you just count click-throughs you will probably cut a lot of your promotion but remember a sale does not come from just one exposure, it comes from lots of exposures.
Remember the “rule of seven” – it is important to get your name out there in association with your product – then people will remember your name and “google” you – but you will not be able to track the enquiry to any one part of your promotion. It is the overall campaign that works.
It is important to understand what is going on and to have faith in your judgement regarding the relationship and balance of the activities.
