On Hopkins's Legacy for Copywriters 

Claude Hopkins is considered the grandfather of advertising. He was one of the first to claim that a scientific account for advertising could be spelled out. This meant that advertisers no longer had to work with guesses and intuitions. Now, they could use precise principles that offer results.
He laid it all out in a book called Scientific Advertising. And now, almost a century after the publication of this small marketing book, people are still learning the fundamentals of advertising from it.
Copywriters are a target for this book, too. A copywriter, be he a beginner or a professional with lots of years, has a lot to learn from a man who made a successful career out of advertising more than one century ago.
What could a copywriter learn from Claude Hopkins? I've recently put up a list with some (if not all) of the lessons we all can learn from this man.

15 principles from Scientific Advertising

Writing the advertisement
1. Write as if you were selling to one person. Address a specific prospect and their concerns instead of speaking vaguely to a crowd.
2. Give people a reason to buy. Don't merely announce that a product exists. Explain what it can do for the customer.
3. Be specific rather than general. Replace vague claims such as “excellent quality” with concrete, verifiable facts that demonstrate quality.
4. Make your claims believable. Support important promises with demonstrations, facts, testimonials, or other relevant evidence.
5. Don't exaggerate. Grandiose claims can make prospects skeptical. Credibility is more valuable than impressive-sounding language.
6. Get to the point. Avoid unnecessary words and entertaining detours that don't contribute to the sales argument.
7. Use language your prospects understand. Clear, familiar wording usually serves the reader better than elaborate language designed to impress. Understanding and persuading customers
8. Study what people already want. Connect your product to existing desires, needs, and buying motives instead of assuming you must create new ones.
9. Emphasize benefits, not merely features. Explain what a product's characteristics mean for the buyer. A feature matters because of the value it provides.
10. Answer objections. Anticipate the questions, doubts, and perceived risks that might prevent someone from buying.
11. Give prospects reasons to trust you. Specific facts, proof, and transparent explanations are more persuasive than simply asking people to believe your claims.
12. Offer samples when they can demonstrate value. Sampling is particularly useful when firsthand experience can convince prospects more effectively than words alone. However, the cost and quality of the resulting customers matter. Testing and improving advertising
13. Measure results instead of relying on opinions. An advertisement that sounds brilliant to its creator may perform poorly in the marketplace.
14. Test alternatives systematically. Compare headlines, offers, and other elements while controlling relevant variables as much as possible. Otherwise, you may not know what caused the difference in results.
15. Track the economics, not just the response. More clicks, inquiries, or sample requests aren't necessarily better if they fail to generate profitable business.
As you can tell, these are all sound pieces of advice for any copywriter in 2026. Follow them, and you are sure to become more successful in your craft.
