Your marketing doesn’t work because it is based on a linear model that approximates growth, when we can measure actual growth in real time.
The math used to measure media and marketing is obsolete.
Social and viral media have created a fractal world that is based on equations that measure growth in real time.
For at least the past 100 years, media has been measured by a straight Euclidean two dimensional plane expressed as GRPs = Reach X Frequency.
However, we know that growth follows a pattern that is seen in fractal geometry and in math such as the Fibonacci series .
