The chosen pattern should meet the communications objectives set in relationship to the nature
of the product, target customers, distribution channels, and other marketing factors. The timing
pattern should consider three factors. Buyer turnover expresses the rate at which new buyers enter
the market; the higher this rate, the more continuous the advertising should be. Purchase frequency
is the number of times the average buyer buys the product during the period; the higher the purchase
frequency, the more continuous the advertising should be. The forgetting rate is the rate at
which the buyer forgets the brand; the higher the forgetting rate, the more continuous the advertising
should be.
