The Complete Guide to E-Commerce Word-of-Mouth Marketing: Review Strategy for Shopee, momo, and Building Seller Reputation
The same moisturizer sits in two storefronts. Store A: 4.8 stars, 1,200 reviews. Store B: 4.2 stars, 87 reviews. The prices differ by less than 5%. A shopper scrolling past both product pages barely needs a moment to decide.
Reviews on Taiwan’s e-commerce platforms are not merely a customer satisfaction metric. They are an algorithmic ranking factor, the deciding input for shoppers who have never heard of you, and the most durable source of traffic outside paid ads. A well-managed review strategy lifts conversion on the exact same product — with no increase in ad spend.
How Review Systems Compare Across Taiwan’s Three Major Platforms
Shopee
Taiwan’s highest-traffic e-commerce platform, and the one where the review mechanics are most directly visible to sellers.
- When reviews are triggered: after the buyer confirms delivery, the platform pushes a review invitation with a 30-day window
- How reviews are displayed: reverse chronological, newest first
- Seller replies: sellers can reply to every review, positive or negative
- Rating impact: product ratings feed directly into search result ranking; overall store ratings determine store badges such as “Preferred Seller”
One characteristic matters more than the rest on Shopee: reviews with photos are displayed more prominently and carry far more visual weight as shoppers browse. Prompting buyers to upload a photo delivers roughly 30–50% more impact than a text-only review.
momo
The main battleground for mid- to high-ticket categories. Its user base skews older (the majority are 35 and up) and pays far more attention to review text than to images.
- Review mechanism: the platform sends a review invitation after purchase, with a field that supports long-form text
- Product page presentation: reviews can be sorted by “most recent” or “highest rated”
- Vendor replies: vendors can reply publicly, and the reply appears directly beneath the review
momo reviews tend to be longer and more specific than Shopee reviews. That cuts both ways for a brand — a strong review is genuinely persuasive, and a negative one does proportionally more damage. Replying to every review, especially the negative ones, is core brand-building work on momo.
PChome 24h
A platform that sellers in 3C (computers, communications, and consumer electronics) and home appliances cannot ignore, with reviews placed prominently on the product page.
- Review system: 1–5 star ratings plus text, with image attachments supported
- Shopper behavior: PChome users comparison-shop harder on high-ticket items — they will line up the same product across multiple sellers, and reviews are the primary basis for that comparison
Four Compliant Ways to Build Positive Reviews
Google’s review policies and every e-commerce platform’s own guidelines explicitly prohibit buying reviews or offering discounts in exchange for a specified rating. Several fully compliant methods, however, can substantially increase review volume.
Method 1: Post-Purchase Thank-You Message with a Prompt
Once a buyer confirms delivery, Shopee sellers can send a thank-you message through the chat function and include a request for a review.
An effective message looks like this:
Thank you for purchasing [product name]!
We hope it arrived on time and is working well for you.
If you're happy with it, we'd love for you to leave a review — it makes
an enormous difference to a small brand like ours.
And if anything is wrong, just tell us and we'll sort it out right away.
One caveat: say only “we’d love for you to leave a review.” Never say “please give us 5 stars” — that violates platform rules.
Method 2: An Insert Card in the Packaging
Slip a small card into the package with a QR code linking to the review page, or a short line of invitation copy.
| Card design element | Why it matters |
|---|---|
| QR code | Jumps straight to the review page, removing friction |
| Invitation copy | Short and sincere; anything that feels engineered backfires |
| Brand warmth | A handwritten look or a genuine thank-you raises the motivation to write |
Method 3: Proactive Customer Service Follow-Up
For high-ticket products, reach out 5–7 days after shipment to ask how the product is working out, resolve anything that came up, and let the review invitation follow naturally. Satisfied customers who have been checked on are roughly three times more likely to leave a review than those who never hear from the seller again.
Method 4: Lean on Repeat Customers
Returning customers with a purchase history and a good relationship with your brand are your most reliable source of reviews. When you launch a new product or revise a spec, reach out to customers who bought something similar and invite them to try it and share their experience.
A Negative Review Is Not the Crisis — Silence Is
Taiwanese e-commerce sellers typically respond to negative reviews in one of two ways: silence or a defensive rebuttal. Both make the situation worse.
Silence shows every prospective buyer reading along that the complaint went unaddressed, which only compounds the distrust.
A defensive rebuttal (“this was caused by improper use” or “our product quality has always been excellent”) signals that the brand does not care how the customer felt, and the reputational cost is steep.
Here is the framework that actually works:
Step 1 — Acknowledge publicly within 48 hours
Thank you for the feedback. We take [the specific issue] seriously, and we're
sorry for the inconvenience this caused.
We'd like to confirm the details with you directly and help resolve it — we've
reached out via chat, so please keep an eye out.
Step 2 — Resolve it privately Use platform chat or a direct message to understand the specifics and offer a remedy (replacement, refund, reshipment). Keep it private; never negotiate a specific compensation figure in a public thread.
Step 3 — Once resolved, ask about updating the review After the issue is settled, it is entirely reasonable to politely ask whether the buyer would consider updating their review. Not everyone will. But a meaningful share of buyers whose problem was handled well are happy to revise theirs to a positive one.
Improving Review Quality: Making Reviews Actually Drive Conversion
Review volume is the foundation. Review content is what genuinely drives conversion.
| Review type | Impact on conversion |
|---|---|
| ”Works great, recommended!” (no detail) | Low |
| ”Package arrived intact” (logistics-only) | Very low |
| ”Two weeks in and my dry skin is noticeably better” (experience-based) | High |
| Reviews with before-and-after photos | Highest |
So how do you get buyers to write higher-quality reviews? Add a single prompting question to your review-request message or insert card:
“If you have a moment, could you share what stood out most about using it? For example, what problem it solved for you, or a detail you particularly liked.”
That question gives the buyer a concrete direction to write in, and it produces substantive text far more reliably than a generic “please leave a review.”
A Cross-Platform Review Strategy
Building reviews on a single platform means forfeiting shoppers everywhere else. An effective e-commerce word-of-mouth strategy builds presence across multiple touchpoints simultaneously.
| Channel | Type of word of mouth | Priority |
|---|---|---|
| Shopee product reviews | Post-purchase rating + text | Core |
| momo product reviews | Detailed written experience | Core |
| Google Maps (physical stores or brand) | Ratings visible in search | High |
| PTT / Dcard experience posts (PTT is Taiwan’s largest online forum; Dcard is a major community platform popular with younger users) | Long-tail SEO traffic | High |
| Instagram UGC | Social proof | Medium |
Once your e-commerce reviews are in good shape, pairing them with experience posts on PTT and Dcard for SEO coverage means the entire path a shopper travels — from searching “[brand name] review” all the way to your product page — is backed by positive word of mouth.
Three Common Misconceptions About E-Commerce Reviews
Caring only about the star rating, not the content. A 4.8-star average made up entirely of hollow “not bad” and “it’s fine” reviews converts far worse than a 4.5-star average where 30% include photos and describe actual use. Review quality beats the number on the badge.
Sprinting for reviews once, then stalling. Sellers concentrate on reviews during a campaign, then go three months without a new one. Platform algorithms reward consistency, and a product page that stops accumulating reviews slides steadily down the search rankings.
Treating a negative review as a private matter. Reviews on e-commerce platforms are public. Every negative review is content that prospective buyers will read while making a decision. Write each reply as an explanation aimed at future buyers, not as a defense aimed at the person who left it.
E-commerce reviews are not a passive system where you wait for customers to say something. They are a word-of-mouth asset you can actively design and optimize.
