The Customer Testimonial Selection Method

R — Original Text (Reading)

Many copywriters realize they should use customer testimonials, so they fill their detail pages with densely packed screenshots of positive reviews. It looks impressive, but in reality the effect is poor. The reason is simple: most positive reviews are vague, "works great" "good quality," and do not hit the customer's core need. Selected testimonials must hit the "core need"—the need the customer most wants to satisfy when spending money.

— Guan Jianming, Chapter 1, 1.6

I — Methodological Skeleton (Interpretation)

The core logic of the Customer Testimonial Selection Method is: use real users' mouths to speak the product's most core selling point for you.

1. Identify the core need: First figure out what need the target customer most wants to satisfy when spending money. It is not all needs, but the single most core one.
2. Select rather than pile up: From a large number of positive reviews, screen out testimonials that directly hit the core need. Better to have few and precise than many and excessive. One precise testimonial is better than ten vague positive reviews.
3. Testimonial arrangement: Put the most powerful one in the most prominent position, and arrange the others in decreasing order of supporting strength.
4. Integrating bestseller hints: If the product has large sales, use specific data ("the choice of 100,000+ families" "ranked first in category sales for 3 consecutive years"); if sales are not yet large enough, use vivid details (describe usage scenarios, before-and-after changes) to convey the feeling that "many people are using it."
5. Testimonial authenticity: Preserve the customer's original language style and colloquial feel. Over-polishing instead reduces credibility.

A1 — Applications in the Book (Past Application)

Case 1: Honey Peach Tasting Panel

• Problem: Honey peach is a niche fruit, and consumers lack awareness of its taste, so testimonials are needed to build trust.
• Use of the method: Form a "tasting panel," invite multiple real consumers to write reviews after tasting, and select testimonials that hit the core need of "high sweetness, delicate flesh."
• Conclusion: The testimonials directly describe the taste experience, such as "every bite is sweet" "sweeter than any apricot on the market," precisely hitting the core need.
• Result: Consumers formed clear expectations for the product's taste, and conversion rate increased significantly.

Case 2: Hyaluronic Acid Serum

• Problem: Hyaluronic acid serum is an efficacy-type skincare product, and consumers are half-believing, half-doubting its effects.
• Use of the method: Select multiple real user reviews, focus on the core need of "long-lasting moisturizing" "skin becomes tender," and include specific usage cycles and changes in feeling in the testimonials.
• Conclusion: Real users describe changes in effects in their own words, which is more persuasive than brand self-praise.
• Result: The click-through rate and dwell time in the testimonial section increased greatly, leading to more orders.

Case 3: Israeli Hair Removal Device (Negative Case)

• Problem: The hair removal device detail page is stuffed with a large number of generic positive review screenshots, things like "works great" and "very satisfied."
• Use of the methodology (failure): There is no curation; all the positive reviews are pasted up in one go, and most of them do not hit the core need of "hair removal is clean and painless."
• Conclusion: The dense screenshots of positive reviews may look impressive, but in reality customers skip over them after a glance, because not a single one speaks to what is in their hearts.
• Result: The conversion effect is far worse than that of competitors who curate a small number of precise testimonials.

A2 — Trigger Scenarios (Future Trigger) ★

In what situations would a user need this skill?

1. Currently writing an e-commerce detail page and needs to decide which user reviews to include.
2. The product has a large number of positive reviews, but it is unclear which ones to choose for the copy.
3. Wants word-of-mouth material to maximize its persuasive power, rather than simply piling up positive review screenshots.
4. A niche new product lacks sales data and needs to use detailed testimonials to convey a sense of "best-selling."
5. Needs to organize scattered positive reviews into a logical sequence of testimonials.

Language Signals

• "There are so many positive reviews, which ones should I choose for the detail page?"
• "How can I make user reviews more persuasive?"
• "My product has a great reputation, but the conversion rate is not high."
• "I need to add some social proof."
• "How do I imply that my product is selling well?"
• "How should buyer shows be arranged for the best effect?"

Distinction from adjacent skills

• Difference from authority-transfer : authority-transfer borrows the endorsement of authoritative institutions/experts, while customer-testimonial borrows the real experiences of ordinary consumers. The former emphasizes "authoritative recognition," while the latter emphasizes "people just like you are using it."
• Difference from factual-evidence : factual-evidence uses objective data and experiments to prove product performance, while customer-testimonial uses subjective experiences and feelings to convey product value. The former is rational proof, while the latter is emotional resonance.

E — Executable Steps (Execution)

1. Identify the core need
   • Completion standard: Write in one sentence the need the target customer most wants to satisfy when spending money, such as "What I most want to buy for 299 yuan is — clean and painless hair removal."
2. Collect and screen testimonials
   • Completion standard: From all positive reviews, screen out the reviews that directly mention the core need, finding at least 3-5. Eliminate all generic positive reviews such as "works great" and "good quality."
3. Arrange the order of testimonials
   • Completion standard: Put the most powerful one first (with specific details, before-and-after comparison, and emotional resonance), and arrange the rest in decreasing order of persuasiveness. Keep the original colloquial feel of each testimonial.
4. Incorporate best-seller hints
   • Completion standard: If there is sales data, use specific numbers at the beginning or end of the testimonial section to imply best-selling status (such as "12,847 mothers have already chosen it"); if there is no sales data, use the number of testimonials and vivid details to imply that "many people are using it."
5. Final check
   • Completion standard: Read through the entire set of testimonials and confirm: (1) each one hits the core need; (2) it reads like a real person speaking; (3) overall it conveys the feeling that "this product is indeed good, and many people are using it."

B — Boundary ★

Do not use this skill in the following situations

• When the product has no real user reviews at all (curation is impossible; seed users must be accumulated first).
• In B2B bulk procurement decisions (corporate procurement values authoritative certifications and data more than personal testimonials).
• When a product has a large number of negative reviews (selecting a few positive reviews to contrast with a large number of negative reviews actually reduces trust).
• When testimonials involve claims of medical effects (may violate advertising law).

Failure modes the author warns about in the book

• Piling up generic praise: Posting all the "works great" and "not bad" positive reviews together looks impressive but in reality not a single one hits the core need, and customers skip over them with one glance.
• Over-polishing testimonials: Rewriting customer reviews to be too neat and too formal makes them lose authenticity, and customers can tell at a glance that they were made up.
• Testimonials disconnected from the core need: The selected testimonials talk about secondary needs (such as nice packaging) rather than the core need (such as clean hair removal).

The author's blind spots / limitations of the era

• The 2017 book's cases are mainly Taobao/JD e-commerce and do not involve new media testimonial forms such as short-video comments and Xiaohongshu notes.
• It does not discuss the issue of verifying the authenticity of testimonials—at a time when "review brushing" is widespread, consumers' trust in positive reviews has declined, requiring stronger authenticity signals.
• It does not involve the orchestration strategies for video testimonials and UGC (user-generated content).
