India's e-commerce boom created a fake review epidemic severe enough that the Government of India published a national standard for online reviews, IS 19000:2022, requiring verified purchases and banning review manipulation. Buyer skepticism is now the default. That is bad news for brands with something to hide, and a structural advantage for brands with nothing to hide.
A wall of five-star reviews on a page you control is a claim, not evidence. Research shows buyers actively hunt for negative reviews to test authenticity3, and a suspiciously perfect on-site rating fails that test instantly.
India's national standard for online consumer reviews5 demands verified purchasers, authenticated reviewers, and no cherry-picking. Trust Cabbage is built on those principles, OTP-verified reviewers, order-linked verified purchases, and no deletion rights for businesses.
When buyers distrust everything a brand says about itself, third-party verified proof becomes the scarcest asset in your funnel. If your product is genuinely good, buyer skepticism is your moat, you just need somewhere neutral for the truth to live.
Two decades of consumer research is unambiguous, here is what the data says, with sources.
270%
Northwestern University’s Spiegel Research Center found that displaying reviews can increase conversion by up to 270%, and by up to 380% for higher-priced products, where buyers perceive more risk. No ad campaign, discount, or redesign delivers that lift.

4.2–4.7
The same research found purchase likelihood peaks between 4.2 and 4.7 stars, and drops for perfect 5.0 ratings, which buyers read as fake. This is why self-hosted, cherry-picked review walls backfire: buyers have learned to distrust perfection.

46%
Nearly half of consumers say they trust online reviews as much as personal recommendations from family and friends. Your customers’ words, hosted somewhere you visibly cannot edit them, are the closest thing to word-of-mouth at scale.

5 reviews
A product’s purchase likelihood rises fastest between zero and five reviews, the jump from no reviews to five is larger than from five to fifty. Which means the collection widget on your very next order confirmation page is your highest-leverage move.
Spiegel Research Center, Northwestern University
Run your own numbers. Take a store doing 10,000 product page visits a month at a 2% conversion rate and ₹1,200 average order value, that's ₹2.4 lakh in monthly revenue.
The Spiegel research measured conversion lifts of up to 270% from displaying reviews1. You don't need anywhere near the full effect for this to be the best-ROI thing you ship this quarter: even a conservative one-fifth of that lift takes the same traffic to roughly ₹3.7 lakh, over ₹1.2 lakh of additional monthly revenue from reviews you collect once and benefit from forever.
And unlike ad spend, reviews don't stop working when you stop paying. They compound: every review strengthens the product page, the company page, and your Google presence simultaneously.
Illustration, conservative scenario
Illustrative only, your lift depends on price point, category, and review volume. Higher-priced products saw larger lifts (up to 380%) in the cited research¹.
No catalogue uploads. No product mapping. No maintenance. The same effort as installing a chat widget.
Claim your company page, open the dashboard, generate your key. Two minutes. No approval queue, no sales call, no onboarding fee.
Add our script tag to your order confirmation page with your own product ID or SKU, whatever your system already uses. Works with any stack: custom site, Shopify, WooCommerce, or one tag in Google Tag Manager.
Customers review at the moment of highest goodwill, right after purchase, on your site. Products auto-register on Trust Cabbage the first time they’re seen. Zero catalogue management, forever.

Neutrality. Reviews hosted where you visibly cannot touch them are the only reviews buyers fully believe.
Reviews trapped inside your website are invisible to search engines. Every Trust Cabbage product page is server-rendered with Schema.org structured data, Google indexes every product, every star rating, every answered question. When a buyer searches "[your brand] reviews", they find verified proof instead of a Reddit thread.
Buyers know you control your own website, that’s why on-site review walls convince no one. Reviews on Trust Cabbage cannot be edited, hidden, or deleted by you, and that constraint is precisely what makes your 4.6 believable. Neutrality is the product.
A company rating says "they’re decent." A product rating says "this exact thing you’re about to buy, 128 people bought it, here’s what happened." Each product gets its own rating, its own reviews, its own public page, its own Google presence.
Shoppers who interact with product Q&A convert at roughly double the rate, because an unanswered question is an abandoned cart. Visitors ask on your product, you answer officially, verified buyers answer from experience. Answers rank on Google for long-tail buyer queries.
The same script tag works in two modes: collect on order pages, display on product pages. Reviews gathered after checkout render back on your own product pages automatically, your site and your Trust Cabbage page stay in sync without a single manual step.
Prefer email? Call our API when an order is delivered and we send a branded review invite, with mandatory unsubscribe links, bounce tracking, and sender reputation managed for you. Compliant by default, so your review requests never look like spam.
"Reviews" is one of the most common words buyers add to a brand search before purchasing. For most Indian brands, that search returns a marketplace listing they don't control, a stale forum thread, or nothing. Reviews collected through Trust Cabbage live on server-rendered public pages with structured data, purpose-built to rank for exactly these searches.

Does this work on oily, acne-prone skin?
Asked by Priya M. · 3 days ago
Yes, it's non-comedogenic and formulated for all skin types. For oily skin, use 2–3 drops at night after cleansing.
I have very oily skin, been using it 2 months, no breakouts. Absorbs fast.
Shoppers who engage with product Q&A convert at roughly double the rate4, because the question they asked was the only thing between them and checkout.
With built-in Q&A, prospective buyers ask directly on your product. You answer with an official badge; verified buyers back you up with lived experience, the most persuasive combination in commerce. Your dashboard flags unanswered questions so nothing slips.
Self-hosted tools help you convert on-site. Global platforms help you get found. Until now you had to pick one, and pay Western prices for the second.

Remember: purchase likelihood peaks at 4.2–4.7 stars, not 5.01, and 82% of buyers go looking for the negative reviews first3. A platform that let you scrub your record would be destroying the very trust you came here to build. These rules are non-negotiable because they are the product.
You cannot delete or hide a product review, ever
You cannot edit what a reviewer wrote
Reviews are OTP-verified and order-linked, one review per customer per product
Paid plans never affect ratings, rankings, or review visibility
You can reply publicly to every review, and flag factually false ones for moderation
Straight answers. No sales fluff.
No. Pass your own product ID or SKU in the snippet, the product is auto-created on Trust Cabbage the first time we see it, linked to your company via your API key. Your catalogue stays in your system; we mirror only what actually gets reviewed. There is nothing to upload, sync, or maintain.
If you run Shopify or WooCommerce, our plugin will handle everything, install and connect your key (coming soon). If your site uses Google Tag Manager, and if you run Facebook or Google ads, it almost certainly does, one GTM tag covers both collection and display with no code deployment. Otherwise, it’s a one-time task of roughly two hours for any developer: the same effort as installing a live-chat widget.
No, and this is a feature, not a limitation. Research shows 82% of shoppers deliberately look for negative reviews, and ratings between 4.2 and 4.7 convert better than a perfect 5.0. A visible, professionally-answered negative review builds more trust than a suspiciously spotless wall. You can reply publicly to every review and flag factually false ones for moderation.
Yes, every product review also counts toward your overall company rating on Trust Cabbage. Collecting product reviews strengthens your entire profile: your company page, your category ranking, and your search presence all compound from the same effort.
Reviews collected through the widget or API carry order context from your own system (order ID, product ID), so they’re marked as verified purchases. Reviewers authenticate with OTP before submitting. One review per customer per product. This mirrors the verified-purchase requirements of India’s IS 19000:2022 standard for online consumer reviews.
Your reviews and your public page stay up, permanently, on any plan, including free. We never hold your reputation hostage. Paid plans gate collection tools and analytics, never the visibility of reviews already earned.
During early access, everything is free, including the API. When paid plans launch, product review collection will sit in the Growth plan, priced for Indian businesses (global platforms charge ₹15,000–50,000+ per month for less). Early access companies will be notified well before anything changes.
Early access companies get the API free, priority onboarding, and a direct line to the team building it.
