Tested Advertising Methods

1. Base advertising on scientific testing, not subjective opinions

Compared with the efficient manufacturing methods of today, many advertising methods are still in the dark ages.

The testing imperative. Advertising must move away from subjective opinions, artistic whims, and unproven theories. Too often, expensive campaigns are launched based on what a client or copywriter personally prefers rather than what actually drives consumer action. By implementing rigorous, scientific testing, advertisers can base their decisions on hard facts and traceable sales results.

The mail-order model. General advertising greatly benefits from adopting the cold-blooded, analytical methods of mail-order practice. In mail-order, every single advertisement must prove its financial viability by generating measurable inquiries or direct sales. This empirical approach eliminates guesswork and ensures that every dollar spent is an investment in a proven performer.

Key metrics to track. To transition from blind spending to scientific precision, advertisers should utilize objective tracking mechanisms. These tools allow businesses to isolate variables and measure the exact performance of individual advertisements.

• Key numbers in coupons to track the source of inquiries
• Store traffic and sales fluctuations during specific promotional runs
• Cost-per-inquiry and cost-per-sale ratios across different media
• Comparative performance of different copy appeals in test cities

2. The headline is the most critical element of any advertisement

Inquiry returns show that the headline is 50 to 75 per cent of the advertisement.

The ultimate gatekeeper. The success of an entire advertising campaign often stands or falls on the headline. If the headline fails to stop the reader, the rest of the copy—no matter how beautifully written or meticulously polished—will go completely unread. The headline acts as a telegraphic message that must compete with hundreds of other distractions for a fleeting second of the reader's time.

Investing creative effort. Copywriters frequently spend hours refining body copy while neglecting the headline until the very last minute. Experienced advertisers reverse this process, dedicating hours or even days to crafting the perfect "stopper." A powerful headline makes writing the subsequent copy a simple task, whereas a weak headline dooms the advertisement to failure from the start.

Headline optimization strategies. To ensure your headline performs at its peak, you must treat it as the primary driver of reader engagement.

• Write dozens of headlines for every single advertisement before choosing one
• Test headlines on objective third parties to ensure clarity and impact
• Avoid "dead" or overly clever headlines that require mental effort to grasp
• Ensure the headline aligns perfectly with the accompanying illustration

3. Appeal directly to the reader's self-interest to capture attention

The best headlines are those that appeal to the reader’s self-interest—headlines that offer the reader something he wants.

The power of self-interest. Human beings are fundamentally self-centered when consuming media; they constantly ask, "What's in it for me?" The most effective advertisements immediately promise a benefit, a solution to a problem, or a way to improve the reader's life. Headlines that offer a clear, desirable reward will always outperform those that rely on abstract concepts or corporate self-praise.

Believability and specifics. While promising a benefit is crucial, the promise must remain entirely believable to avoid triggering the reader's skepticism. Using specific figures, times, and quantities instead of broad generalities dramatically increases the credibility of your claim. For instance, promising to help someone "save $140 in one month" is far more compelling and believable than promising to make them "rich overnight."

Core self-interest appeals. Advertisers should focus on timeless human desires that consistently drive consumer behavior.

• Making or saving money to achieve financial independence
• Improving health, vitality, and physical appearance
• Gaining popularity, personal charm, and social prestige
• Saving time, ending drudgery, and increasing leisure
• Securing safety, comfort, and peace of mind in old age

4. Inject news and curiosity to strengthen your headlines

News, curiosity, and self-interest have always been powerful factors in making good ads.

The value of news. People are naturally drawn to what is new, novel, and current. If your product has a new feature, a new use, or represents a fresh discovery, you must announce it in a big, bold way. Incorporating an announcement quality into your headlines immediately elevates the perceived importance of your message, making it feel like an essential piece of information rather than a mere sales pitch.

The curiosity catalyst. Curiosity is a powerful tool to pull readers into your body copy, but it must be handled with extreme care. A headline that relies solely on curiosity without hinting at a benefit or offering news will usually fail. The most successful curiosity headlines combine a puzzling or intriguing statement with a strong undercurrent of self-interest, forcing the reader to read further to find the answer.

High-performing trigger words. Certain words have stood the test of time, consistently maintaining their ability to stop readers and arouse interest.

• "Announcing" and "Introducing" to signal important news
• "New" and "Now" to emphasize freshness and immediacy
• "At last" to suggest a long-awaited solution has arrived
• "Wanted" to create a sense of demand and opportunity
• "Which" and "Why" to provoke curiosity and self-examination

5. Use simple, clear, and telegraphic language to reach the masses

In writing advertising copy, use words you would expect to find in a fifth-grade reader.

The necessity of simplicity. The average reading public has a lower level of literacy and a shorter attention span than most copywriters assume. To write successful copy for the masses, you must banish sophisticated, pompous, and literary language. Your message must be instantly understandable to a distracted reader who is glancing through a publication or watching a screen on the run.

Reducing mental friction. Every complex word, long sentence, or confusing layout acts as a barrier that drains the reader's limited mental energy. If a reader has to pause even for a second to figure out what you mean, you have likely lost them forever. By using short paragraphs, brief sentences, and simple words, you make the reading process effortless and inviting.

Rules for mass appeal. To ensure your copy resonates with the widest possible audience, adhere to strict guidelines of clarity.

• Avoid industry jargon, abstract terms, and "clever" double meanings
• Use the present tense and speak directly to the reader using "you"
• Keep paragraphs short to avoid intimidating blocks of solid type
• Put clear, informative captions under every single illustration
• Avoid excessive punctuation, exclamation marks, and confusing contractions

6. Write long, fact-packed copy to maximize selling power

Remember the saying, "The more you tell, the more you sell."

The case for length. There is a common misconception in advertising that "nobody reads long copy." While it is true that casual glancers won't read it, your actual prospects—the people who are genuinely interested in buying your product—will eagerly read every word if it provides valuable information. Long copy allows you to present a complete, robust sales talk that addresses every potential objection.

Packing copy with facts. Long copy should never be filled with empty fluff, flowery adjectives, or repetitive style-conscious prose. Instead, it must be packed with concrete facts, specifications, statistics, and proof of performance. A factual, informative presentation builds trust and gives the prospect tangible reasons to justify their purchase decision.

Structuring long copy for readability. To prevent long copy from overwhelming the reader, it must be organized with visual and structural aids.

• Use bold, intriguing subheads to break up the text and tell a quick story
• Present key features and benefits in clear, easy-to-read bulleted lists
• Start with a short, punchy first paragraph that continues the headline's thought
• Squeeze out all unnecessary words by writing long and then boiling it down
• End with a powerful, direct call to action that tells the reader exactly what to do

7. Dramatize dull products to make them exciting and memorable

By its attention value it can make a small advertising appropriation do the work of a large appropriation.

The power of drama. Many products are inherently dry, technical, or uninteresting to the average consumer, such as office stationery, grave vaults, or statistics. The copywriter's job is to inject human interest and emotional tension into these subjects. By framing a dull product within a dramatic, real-life situation, you capture the reader's imagination and make your message stick.

Human-interest narratives. One of the most effective ways to dramatize a product is to tell a story. A narrative about a personal triumph, a social embarrassment avoided, or a domestic conflict resolved immediately engages the reader's emotions. This emotional connection bypasses intellectual resistance, making the reader far more receptive to the eventual sales pitch.

Proven dramatic copy angles. Several classic storytelling frameworks have consistently proved successful in revitalizing tired or dull product categories.

• The "before and after" contrast showing a dramatic transformation
• The "overheard conversation" revealing hidden thoughts or social anxieties
• The "shame and embarrassment" angle highlighting a problem the product solves
• The "hero's journey" where an unlikely protagonist achieves sudden success
• The "unbelievable challenge" that dares the reader to test the product's claims

8. Use highly visible, action-oriented coupons and offers

The key number is an invention that has done as much for the science of advertising as the X-ray has done for the science of medicine.

The role of the coupon. A coupon is not merely a convenient order form; it is a powerful psychological trigger that drives action. It draws the reader's eye, clearly defines the offer, and serves as a physical reminder to respond. By making the coupon highly visible and easy to use, you significantly lower the barrier to entry for prospective customers.

Sweetening the offer. To maximize coupon response, the offer itself must be incredibly attractive. Whether you are offering a free booklet, a product sample, or a special discount, adding a "sweetener"—such as a free bonus gift or a risk-free trial period—can dramatically boost returns. The copy within the coupon should also be written as a mini-sales talk, reinforcing the primary benefits of taking action.

Best practices for coupon design. Implementing specific design and copy techniques can greatly enhance the effectiveness of your coupons.

• Print the specific monetary or promotional value clearly on the coupon
• Include a clear, prominent "no obligation" or "money-back" guarantee
• Provide multiple payment options, including credit cards and billing plans
• Use a business reply format that requires no postage stamp from the sender
• Set a strict, visible expiration date to create a sense of urgency

9. Leverage split-run testing to eliminate variables and find winners

Every variable that might affect the result of the test is removed.

The ultimate testing method. Traditional copy testing is often plagued by external variables such as changing weather, different page positions, and fluctuating economic conditions. Split-run testing solves this problem by printing two different advertisements in the exact same position on the exact same day, each appearing in exactly half of the publication's circulation. This ensures a perfectly controlled, head-to-head scientific comparison.

Measuring fine distinctions. Because split-run testing is so incredibly accurate, it allows advertisers to measure the impact of very small changes. You can test different headlines, different illustrations, or even different payment terms while keeping the rest of the advertisement identical. The resulting data provides a precise, mathematical measurement of which element performs best, removing all subjective debate.

Executing a split-run test. To get the most out of your split-run testing program, follow a structured, iterative process.

• Select a reliable "Control Ad" to act as a consistent measuring stick
• Test one variable at a time to isolate the exact cause of performance differences
• Use small, inexpensive ad sizes to test multiple variations quickly
• Roll out the winning elements nationally across all media channels
• Continuously test new ideas against your reigning champion to drive ongoing improvement
