Don’t confuse your current customers with your target customers.
No one can execute a marketing plan perfectly. Perhaps you have a product or service offering that appeals to customers who are not your target customers. Possibly some of your distribution attracts customers who are not your target customers. Or you have an offering that’s priced too high or too low for your target customers. Regardless of the reason, your brand is going to attract buyers who are not your target customers.

In consumer goods product categories, accidental buyers usually don’t represent a problem for the marketer; they only represent that execution of marketing mix tactics could be improved. In business to business product categories, accidental buyers may mean that an end-user has purchased and is using a product that is not suitable for their application. This misapplication may lead to dissatisfaction with the brand, or worse, product liability issues.
