Hello. Just wondering why companies advertise.
Obviously they have to let people know they exist. Advertising is one way. But is it the best way? And is it worth the cost?
Most advertising I've seen is irrelevant. Why? Because it doesn't target a specific group, namely people who are interested in the company. Instead, it targets the entire market to which it's distributed, and charges for that entire market, of which only a subset may be interested in the company.
Now many would say it's the best way to get new customers. I don't agree. A mass blitz only gets a passing glance from the uninterested. If you want proof of that, check the Ontario Election voter turnout.
What is a better way for companies to get new customers? More tomorrow.
