For instance, the advertiser of a dentifrice may spend much space and money to educate people to brush their teeth. Tests which we know of have indicated that the cost of such converts may run from $20 to $25 each. Not only because of the difficulty, but because much of the advertising goes to people already converted.
Such a cost, of course, is unthinkable. One might not in a lifetime get it back in sales. The maker who learned these facts by tests make no attempt to educate people to the tooth brush habit. What cannot be done on a large scale profitably can not be done on a small scale. So not one line in any ad is devoted to this object. This maker, who is constantly guided in everything by keying every ad, has made remarkable success.
Another dentifrice maker spends much money to make converts to the tooth brush. The object is commendable, but altruistic. The new business he creates is shared by his rivals. He is wondering why his sales increase is in no way commensurate with his expenditure.
An advertiser at one time spent much money to educate people to the use of oatmeal. The results were too small to discover. All people know of oatmeal. As a food for children it has age-old fame. Doctors have advised it for many generations. People who don't serve oatmeal are therefore difficult to start. Perhaps their objections are insurmountable. Anyway, the cost proved to be beyond all possible return.
There are many advertisers who know facts like these and concede them. They would not think of devoting a whole campaign to any such impossible object. Yet they devote a share of their space to that object. That is only the same folly on a smaller scale. It is not good business.
No one orange grower or raisin grower could attempt to increase the consumption of those fruits. The cost might be a thousand times his share of the returns. But thousands of growers combined have done it on those and many other lines. There lies one of the great possibilities of advertising development. The general consumption of scores of foods can be profitably increased. But it must be done on wide co-operation.
No advertiser could afford to educate people on vitamins or germicides. Such things are done by authorities, through countless columns of unpaid-for space. But great successes have been made by going to people already educated and satisfying their created wants.
It is a very shrewd thing to watch the development of a popular trend, the creation of new desires. Then at the right time offer to satisfy those desires. That was done on yeast's, for instance, and on numerous antiseptics. It can every year be done on new things which some popular fashion or widespread influence is brought into vogue. But it is a very different thing to create that fashion, taste or influence for all in your field to share.
There are some things we know of which might possibly be sold to half the homes in the country. A Dakin-fluid germicide, for instance. But the consumption would be very small. A small bottle might last for years. Customers might cost $1.50 each. And the revenue per customer might not in ten years repay the cost of getting. Mail order sales on single articles, however popular, rarely cost less that $42.50 each. It is reasonable to suppose that sales made through dealers on like articles will cost approximately as much. Those facts must be considered on any one-sale article. Possibly one user will win others. But traced returns as in mail order advertising would prohibit much advertising which is now being done.
Costly mistakes are made by blindly following some ill-conceived idea. An article, for instance, may have many uses, one of which is to prevent disease. Prevention is not a popular subject, however much it should be. People will do much to cure trouble, but people in general will do little to prevent it. This has been proved my many disappointments.
One may spend much money in arguing prevention when the same money spent on another claim would bring many times the sales. A heading which asserts one claim may bring ten times the results of a heading which asserted another. An advertiser may go far astray unless he finds out. A tooth paste may tend to prevent decay. It may also beautify teeth. Tests will probably find that the latter appeal is many times as strong as the former. The most successful tooth paste advertiser never features tooth troubles in his headlines. Tests have proved them unappealing. Other advertisers in this line center on those troubles. That is often because results are not known and compared.
A soap may tend to cure eczema. It may at the same time improve complexion. The eczema claim may appeal to one in a hundred while the beauty claims would appeal to nearly all. To even mention the eczema claims might destroy the beauty claims.
A man has a relief for asthma. It has done so much for him he considers it a great advertising possibility. We have no statistics on this subject. We do not know the percentage of people who suffer from asthma. A canvass might show it to be one in a hundred. If so, he would need to cover a hundred useless readers to reach one he wants. His cost of result might be twenty times as high as on another article which appeals to one in five. That excessive cost would probably mean disaster. For reasons like these every new advertiser should seek for wise advice. No one with the interests of advertising at heart will advise any dubious venture.
Some claims not popular enough to feature in the main are still popular enough to consider. They influence a certain number of people - say one-fourth of your possible customers. Such claims may be featured to advantage in a certain percentage of headlines. It should probably be included in every advertisement. But those are not things to guess at. They should be decided by actual knowledge, usually by traced returns.
This chapter, like every chapter, points out a very important reason for knowing your results. Scientific advertising is impossible without that. So is safe advertising. So is maximum profit. Groping in the dark in this field has probably cost enough money to pay the national debt. That is what has filled the advertising graveyards. That is what has discouraged thousands who could profit in this field. And the dawn of knowledge is what is bringing a new day in the advertising world.
