Local marketing checklist
Run through this once a quarter. It is deliberately short: these are the items that move local results, not everything that could theoretically be done.
The last item is the one that changes decisions
Knowing where your last ten customers came from turns marketing from a matter of opinion into a matter of record. It is usually a surprise, it is usually concentrated in one or two channels, and it makes the question of where to spend the next quarter's effort answer itself.
