Where to Add Reviews on Shopify: One Doubt per Step, From Homepage to Post-Purchase
You tap it. Just to be sure.
A new page opens on the three most recent reviews. All three are negative.
You don't go back to the cart.
A version of this happened on a real store, and we'll come back to it at step four. First, rewind to where this shopper started.
Why More Reviews in More Places Doesn't Mean More Sales
Reviews do work. In Baymard Institute's testing, 95% of users relied on reviews to learn about products, and Northwestern's Spiegel Research Center found that displaying them lifted conversion by 190% on lower-priced products and 380% on higher-priced ones.
But those numbers measure proof meeting a question the shopper already had. The badge in the cart met a shopper who had stopped asking, and handed them a new question.
A Shopify store has six steps between the ad and the second order, each with its own doubt. We'll keep count as we go.
Step 1: The Homepage
On the homepage, reviews should prove the brand is real and people buy from it, so show a store-wide rating with its count and its source near the top.
You tapped an Instagram ad on the way home. You've never heard of this brand. Before you read a word of the copy, your eyes go looking for evidence that other people have bought here and been fine.
"Rated 4.8 from 3,200 reviews," with the review platform's name beside it, answers that. "Loved by thousands" doesn't, because nothing in it can be checked. The count matters most. In a Baymard survey of more than 5,170 people, nearly twice as many chose a product rated 4.5 by 57 users over one rated 5.0 by four.
A carousel of five-star quotes signed "Sarah K." sits somewhere in between. It's pleasant, and anyone could have typed it.
If your ads send people straight to product pages, this doubt travels with them, and step 3 has to answer it too.
Doubts answered: 1 of 6.
Step 2: The Collection Page
On collection pages, reviews help shoppers choose between products, so every product card needs its star rating and the number of ratings next to it.
You tap Shop All. Twelve products in a grid, same white background, prices within a few dollars of each other. They start to blur.
Stars break the tie, and the count beside them is what makes them believable. Baymard's point is simple: a 4.5 from five reviews and a 4.5 from a thousand are different claims. When products have similar ratings, the count lets a shopper tell them apart without opening every page. Most large sites have caught on. In Baymard's 2022 benchmark, 5% of sites still left the count out of their product lists, down from 25% in 2015.
Doubts answered: 2 of 6.
Step 3: The Product Page
On the product page, reviews should answer whether the product works for this particular shopper, so put the rating and count by the title, link them to the reviews, and let people reach the low ratings in one tap.
The photos look great. Photos always look great. You scroll past them, looking for someone with your size and your problem, and for the person who hated it.
That last part matters. In Baymard's testing, 53% of users actively sought out the negative reviews, yet 43% of the world's 60 top-grossing ecommerce sites show no ratings distribution at all. A clickable distribution turns "show me the three-star reviews" into one tap, and a page that makes them easy to find looks like it has nothing to hide.
Customer photos and video show the product in use, which text can't. Videowise, for example, turns TikTok and Instagram clips into shoppable video, with a free plan on its App Store listing. Disclosure: Videowise is a Weblics partner; it would be the example here either way. Video adds weight, so check your LCP report the week after installing.
Some review widgets also load after the page and shove everything below them down. Shopify's performance team notes that many apps "do not save space for the content they inject on the page," so ask your developer to reserve the widget's height.
Now a test we expected to win. At Weblics, we pinned a fixed set of reviews to the top of the review block on a wellness brand's product pages. The idea seemed obvious: put the best proof where everyone sees it. The test ran from July 2025 to March 2026 on about 31,600 visitors per version. The pinned version converted about 5% worse, 3.33% against 3.50%, and revenue per visitor was flat. The difference wasn't statistically significant, so we can't say pinning hurt. We can say it didn't help, and we didn't ship it. Our best guess, and it is a guess: a pinned set removes the sorting shoppers do themselves, and the 53% who go looking for the bad reviews don't trust a page that has done the choosing for them.
Doubts answered: 3 of 6.
Step 4: The Cart
In the cart, reviews have one job: reassure without giving the shopper a way out. A line about your guarantee works. A badge that links to another site can cost you the order.
This is where we started. The badge under the checkout button said Excellent and linked to Trustpilot, and Trustpilot opened on the three most recent reviews, all negative. That badge was a shop assistant who walks you to the till and hands you the complaints book on the way.
We found it during a cart review on a client store and took it out. We didn't A/B test the removal, so we can't put a number on what it was costing, and we're not going to invent one. What we can say is what any shopper can check: the badge opened a page the store didn't control, at the one moment the store most needed control.
Remember the 53% who go looking for negative reviews. A link under the checkout button hands them the search result at the worst possible moment, on a page you don't control.
Our rule for the cart: keep any proof on the page and keep it short. The rating as plain text, or a line about returns. Nothing that opens somewhere else.
Doubts answered: 4 of 6.
Step 5: The Checkout
At checkout the doubt is about payment, not the product, so review stars don't answer it, and on most Shopify plans you can't add them anyway.
You're typing a card number on a bus. The only question left is whether this site deserves it. In Baymard's latest abandonment survey, 19% of shoppers who abandoned an order, leaving aside those who were just browsing, said they didn't trust the site with their card details.
Shopify only lets Plus stores add app content to the information, shipping and payment steps. On every other plan, the checkout is Shopify's own, and its familiar layout is part of the reassurance. On Plus, the logic from our checkout optimization guide applies: anything you add before the pay button is one more decision between the shopper and the order.
Doubts answered: 5 of 6.
Step 6: After the Purchase
After the purchase, the job changes. This is where you collect reviews and photos, and it makes the proof every other step uses.
Three weeks later, the order has arrived and you've used it. An email asks how it's going, and whether you'd add a photo. You take one in the kitchen and send it.
A month from now, that photo is on the product page. Someone who tapped an ad on the way home, who has never heard of the brand, scrolls past it looking for someone like them.
This is how a brand ends up with customers doing the selling. Ask once the product has had time to work, which for most products means some days after delivery. Ask for a photo, and make it a single tap. You can reward people for leaving a review, but under the FTC's 2024 rule on reviews and testimonials, you can't make the reward depend on the review being positive.
Doubts answered: 6 of 6.
When Reviews Are Better Not Shown
Spiegel found that the benefit of each additional review starts falling off quickly after the first five, which makes those first five the ones doing the work. Below that, even a perfect score is thin evidence, as Baymard's 4.5 from 57 against 5.0 from four shows. Our rule of thumb for a new product: lead with something that can be checked, like a guarantee or a store-wide rating clearly labeled as store-wide.
A low average is a different problem. Spiegel found purchase likelihood peaks between 4.0 and 4.7 stars. If a product sits below that, the product or the expectations around it need work. Moving the stars won't fix it.
There's also a line you can't cross. Choosing not to show a widget is a design decision. Hiding negative reviews and letting the rest pass as all of them is another matter: the FTC's 2024 rule prohibits misrepresenting that displayed reviews represent all or most of those submitted when some have been suppressed, and it allows civil penalties. This isn't legal advice, so if you're unsure where your setup falls, ask a lawyer.
The ten-minute version of this walk: phone in hand, open your own store.
• Homepage: is there a store-wide rating with a count and a source near the top?
• Collection: does every product card show stars and a count?
• Product page: does the rating by the title jump to the reviews, and can you reach the low ones in one tap?
• Cart: is there anything under the checkout button that opens another page?
• Checkout: has anything been added between the shopper and the pay button?
• After purchase: when does the review request go out, and does it ask for a photo?
You don't need a developer to check any of it, and every change on this list can be undone.
In Baymard's testing, about half of shoppers went looking for the bad reviews anyway. What you decide is whether they find them at step 3, behind a three-star filter you control, or at step 4, on someone else's site.
Once you know where reviews go, the next question is which app collects and displays them best. Our comparison of Judge.me, Loox, Yotpo and Junip, priced at your order volume, is the next guide in this series.
Reviews don't sell because they're everywhere. They sell because they're where the doubt is.

Do you have any questions left?
Here are the answers for you
Match reviews to the doubt at each step: a store-wide rating with its count on the homepage, stars and counts on every collection card, a rating by the title and a clickable distribution on the product page, and a short on-page reassurance in the cart. After purchase is where you collect new reviews and photos.
Yes, as store-wide proof rather than product testimonials. A rating with its count and source, such as 4.8 from 3,200 reviews, answers a new visitor's first doubt, which is whether the brand is real. In a Baymard survey, nearly twice as many people preferred a 4.5 rating from 57 users over a 5.0 from four.
Keep it short and on the page. A guarantee or returns line can reassure, but avoid badges that link to another site. In Baymard's testing, 53% of users actively sought out negative reviews, and a link under the checkout button can take them there at the worst moment.
Only on Shopify Plus, which is the only plan where apps can add content to the information, shipping and payment steps. At checkout the shopper's doubt is about payment security, so review stars rarely answer it.
Around five. Northwestern's Spiegel Research Center found that a product with five reviews was far more likely to be bought than one with none, and that the benefit of each additional review falls off quickly after the first five. Before then, lead with a guarantee or a clearly labeled store-wide rating.
Choosing not to display a review widget is a design choice. Suppressing negative reviews while presenting the rest as all or most of your reviews is prohibited under the FTC's 2024 rule on consumer reviews and testimonials, which allows civil penalties. This isn't legal advice.
