Scientific Advertising - Claude C. Hopkins

Claude C. Hopkins (1866–1932) was one of the great advertising pioneers. He believed advertising existed only to sell something and should be measured and justified by the results it produced.

He worked for various advertisers, including Bissell Carpet Sweeper Company, Swift & Company and Dr. Shoop's patent medicine company. At the age of 41, he was hired by Albert Lasker owner of Lord & Thomas advertising in 1907 at a salary of $185,000 a year, Hopkins insisted copywriters research their clients' products and produce "reason-why" copy. He believed that a good product and the atmosphere around it was often its own best salesperson, and as such he was a great believer in sampling.

To track the results of his advertising, he used key-coded coupons and then tested headlines, offers and propositions against one another. He used the analysis of these measurements to continually improve his ad results, driving responses and the cost effectiveness of his clients' advertising spend.

Hopkins is one of the father's of modern day marketing. While working for the Bissel Carpet Sweeper Company, at Hopkins' sent out five thousand letters offering carpet sweepers as Christmas presents - one thousand people sent in orders. He also convinced Bissel manufacturers to offer more variety of carpet sweepers, such as making them with twelve different types of wood. Immediately after these changes, Bissel sold two hundred fifty thousand in three weeks.
