Over 100 years ago, copywriter Claude Hopkins was earning the equivalent of Babe Ruth money—$100,000 a year writing direct mail campaigns. His work wasn’t just successful. It defined a generation of advertising excellence and established principles that copywriters still reference today.
Now, two comprehensive collections showcase the breadth of Hopkins’ genius: 463 ads spanning campaigns for Pepsodent, Goodyear Tires, Palmolive Soap, Schlitz Beer, Quaker Oats, and others. Part I presents 256 ads across six campaigns. Part II adds another 207 from six different brands.
What makes these collections valuable isn’t nostalgia. Hopkins pioneered scientific advertising principles that remain effective a century later. His emphasis on testing, measurable results, and reason-why copy transformed advertising from guesswork into a predictable discipline. David Ogilvy, the Father of Advertising, credited Hopkins’ book Scientific Advertising with changing the course of his life, recommending that “nobody should be allowed to have anything to do with advertising until he has read this book seven times.”
The ads themselves reveal how Hopkins constructed campaigns that sold products by understanding human psychology and creating specific, believable reasons to buy. From Pepsodent’s film-on-teeth positioning to Schlitz’s tour of their brewing process, Hopkins built brands by making the commonplace seem remarkable.
For copywriters today, these collections offer more than historical curiosity. They demonstrate timeless principles: headlines that demand attention, copy that builds belief through specifics, and closes that make the next step obvious.
Mastering the Close: The Fourth P
After you’ve made a powerful promise, painted a vivid picture, and proven your claims, you still face the most critical moment in any sales letter: the close. According to direct marketing expert Michael Masterson, this is where most copywriters stumble.
Masterson learned this lesson early. As a teenage door-to-door salesman, he could get in the door and deliver a compelling presentation. But when it came time to ask for the sale, he froze. That psychological barrier—the fear of pushing too hard—killed his results. Years later, working in direct mail, he discovered that the same principle applies to copywriting: if you can’t close strongly, everything else fails.
The solution starts with belief. If you don’t genuinely think your prospect needs what you’re selling, your copy will betray that doubt. Masterson recommends a three-step mental process: realize you’re not the target prospect, imagine her life and problems in detail, and learn to care about solving them. When you truly want your prospect to benefit, your enthusiasm becomes authentic and persuasive.
The mechanics of closing involve what Masterson calls the “False Close”—a technique where you suggest the sale is complete, then add another benefit or two before the final ask. Think of the old Ginsu Knife commercials: “But wait! There’s more!” This approach lets buyer anxiety subside while layering on additional value. Sometimes there are two or three False Closes, each adding urgency and desire.
The Final Close, meanwhile, should transport readers back to the core emotional benefit. It’s not just a recap—it’s a carefully crafted moment that makes the promise irresistible. Masterson emphasizes spending serious time on this section, treating it like a punch line that completes a long story.
One warning: avoid being too linear. If readers can predict your next move, they’ll mentally check out. A well-executed False Close keeps them slightly off balance, engaged and unable to categorize your approach.
Why Claude Hopkins Still Matters
When you’re building a landing page or writing sales copy, the quality of your source material matters more than your technical skills. That’s the counterintuitive lesson one copywriting instructor shares about why he chose Scientific Advertising by Claude Hopkins as the foundation for his course.
Published over a century ago, the book is firmly in the public domain and available free online. But accessibility isn’t why Hopkins’ work remains relevant. The real reason is timelessness. David Ogilvy insisted that nobody should work in advertising without reading Scientific Advertising seven times. A century later, that recommendation still stands.
What makes the book work as a teaching tool is that great landing pages are born from great content. If your product or service is weak, no amount of copywriting wizardry will save you. Hopkins understood this. His campaigns for Pepsodent, Schlitz, and Palmolive weren’t clever tricks—they were rooted in genuine value propositions that resonated with real needs.
Interestingly, the instructor embraces rather than apologizes for the book’s archaic language. The vocabulary and sentence structure can sound awkward by modern standards, but that’s precisely the point. Learning to translate century-old copy into contemporary messaging teaches you how to work with any voice or style—a skill copywriters need when serving diverse clients.
The lesson extends beyond Hopkins. Whether you’re writing for a tech startup or a heritage brand, your ability to extract and modernize the core value proposition determines your success. Hopkins proved that advertising could be scientific, measurable, and repeatable. His methods worked in 1923. They work today.
