You see other ads which you may not like as well. They may seem crowded or verbose. They are not attractive to you, for you are seeking something to admire, something to entertain. But you will note that those ads are keyed. The advertiser knows that they pay. The probability is that out of scores of traced ads the type which you see has paid best.

Many other ads which are not keyed now were keyed at the beginning. They are based on known statistics. They won on a small scale before they ever ran on a large scale. Those advertisers are utilizing their enormous powers in full.

Advertising is prima facie evidence that the man who pays believes that advertising is good. It has brought great results to others, it must be good for him. So he takes it like some secret tonic which others have endorsed. If the business thrives, the tonic gets the credit. Otherwise, the failure is due to fate.

That seems almost unbelievable. Even a storekeeper who inserts a twenty-dollar ad knows whether it pays or not. Every line of a big store's ad is charged to the proper department. And every inch used must the next day justify its cost.

Yet most national advertising is done without justification. It is merely presumed to pay. A little test might show a way to multiply returns. Such methods, still so prevalent, are not very far from their end. The advertising men who practice them see the writing on the wall. The time is fast coming when men who spend money are going to know what they get. Good business and efficiency will be applied to advertising. Men and methods will be measured by the known returns, and only competent men can survive.

Only one hour ago an old advertising man said to the writer, "The day for our type is done. Bunk has lost its power. Sophistry is being displaced by actuality. And I tremble at the trend."

So do hundreds tremble. Enormous advertising is being done along scientific lines. Its success is common knowledge. Advertisers along other lines will not much longer be content.

We who can meet the test welcome these changed conditions. Advertisers will multiply when they see that advertising can be safe and sure. Small expenditures made on a guess will grow to big ones on a certainty. Our line of business will be finer, cleaner, when the gamble is removed. And we shall be prouder of it when we are judged on merit.
