If you want customers to pick up your business card, make it the most interesting.

If you want customers to find your website, make it the most useful.

If you want customers to see your yellow page ad, make it the largest.

If you want customers to refer you, make them the happiest.

The point here, no matter how important, is not to make your customers happy. My point is that these facts are not interchangeable. You won’t get more people to pick up your business card by making your prices low. Just like you wont get more people to visit your website just because it’s happy. Each part of your marketing efforts are independent paths towards your overall brand.

If you want more customers, make each part better. You won’t get new customers through your website if you don’t make it better.
