A review popup shows a real customer review, or a product’s average rating, as a small notification while shoppers browse your store. If you already collect reviews in Judge.me, you can show them as notifications without writing any code. The rules are simple: show reviews exactly as customers wrote them, and keep the full list on the product page.
This post covers when review notifications help, which review source to use, how to keep them honest, and how to set one up step by step. For how reviews fit with recent sales, visitor counts and stock alerts, start with our social proof guide for Shopify.
What is a review popup?
It’s a short notification that quotes a review or a rating. A typical one reads “Rob rated Linen Shirt 5/5”, with the stars and a line from the review below. Shoppers can click it to open the product.
Most stores already show reviews in two places. A review popup adds a third:
| Format | Where it shows | What it’s good at |
|---|---|---|
| Star rating | Near the product title, on collection cards | A quick sign of quality at a glance |
| Review section | Lower on the product page | The full picture, good and bad |
| Review popup | In a corner, on any page you choose | Bringing reviews into view on pages where they don’t appear |
The popup doesn’t replace the review section. It points to it. Shoppers who want details still scroll down and read everything.
When do review notifications help?
They help most when shoppers see your products before they see your reviews. Some good fits:
- Home and collection pages. Reviews usually live on product pages. A popup shows proof earlier, before a shopper picks a product.
- Long product pages. If the review section sits far below the add to cart button, a popup puts one real review near the decision.
- Stores with few orders but good reviews. A recent sales feed looks thin on a quiet store. A strong review from last month still reads well, because reviews don’t go stale the way “2 minutes ago” does.
And cases where they usually don’t help:
- Very few reviews. If you have five reviews in total, shoppers will see the same ones again and again. Collect more first.
- Stacked popups. A review, a sales popup, a visitor count and a countdown at once feel like a hard sell. Pick one or two.
- Checkout-focused pages. On the cart page, shoppers have already chosen. A popup there is more likely to distract than reassure.
Reviews are the type of social proof that shows the product after it arrived. That’s why they often matter more than activity signals like sold count badges or cart activity notifications.
Judge.me reviews or Shopify product ratings: which source should you use?
Use Judge.me if that’s where your reviews live, and the Shopify rating fields if you use another review app. The two sources show different things.
Judge.me reviews are individual reviews. Judge.me has an API that other apps can read with your private API token, so a popup can show the reviewer’s name, the stars, a quote from the review and the product.
Shopify product ratings are totals per product. Shopify has two standard product metafields, reviews.rating (the average) and reviews.rating_count (the number of ratings). Shopify asks product rating apps to write to them, so many review apps fill them in.
| Judge.me reviews | Shopify product ratings | |
|---|---|---|
| What a popup shows | One review: name, stars, a quote | One product: average rating and number of ratings |
| Example | “Rob rated Linen Shirt 5/5” | “120 customers rated Linen Shirt 4.6/5” |
| Works with | Judge.me only | Review apps that write the standard rating fields |
| Setup | Paste your Judge.me private API token | Nothing extra, if your review app fills the fields |
The names and numbers in the examples are placeholders. If you’re not sure your review app writes the standard fields, open a reviewed product in your Shopify admin and look for the rating fields in its metafields.
How do you keep review popups honest?
Show real reviews, word for word, and don’t make the popup look like your whole review record. In the US, the FTC’s Rule on the Use of Consumer Reviews and Testimonials (16 CFR Part 465) covers both points.
Section 465.2 bans businesses from writing or creating reviews that misrepresent whether the reviewer exists, whether they used the product, or what their experience was. Section 465.7(b) covers review suppression. It applies when a business implies that the reviews shown in its review section are most or all of the reviews it got, while it hides reviews because of their rating or negative tone. The rule lists fair reasons to hold a review back, such as abusive content, personal information or a review you reasonably believe is fake.
In practice, for a review popup:
- Show reviews as written. Don’t fix the wording, combine reviews or make one up to fill a gap.
- Keep the product page unfiltered. Your main review section should show low ratings too, with your replies.
- Treat the popup as a highlight. Don’t add copy like “what all our customers say” to a feed of top-rated reviews.
- Disclose incentives. If a reviewer got a discount or free product, the disclosure that sits with the review in your review app shouldn’t vanish in the popup. If it can’t come along, leave that review out of the feed.
- Use reviews of the right product. Don’t show a review of one item as if it were about another.

How do you show Judge.me reviews as popups in Sam FOMO?
Sam FOMO has a Product Reviews notification that shows reviews from Judge.me or ratings from Shopify’s product rating fields. It’s free to install and rated 4.6★ from 17 reviews on the Shopify App Store (Oct 2026). Here’s the setup:
- Turn on the app embed. Popups only show once the Sam Boost Sales app embed is on in your theme (install and enable).
- Create the notification. Go to Notifications, click Create notification, pick Product Reviews and click Add (create a notification).
- Pick the source. Under Review source, choose Judge.me reviews.
- Get your Judge.me token. In your Judge.me admin, go to Settings > Integrations and click View API tokens. Copy the Private API Token.
- Paste the token into Judge.me private API token in Sam FOMO.
- Set the filters. Choose a Minimum rating (5 stars, 4 stars and up, or 3 stars and up) and the Maximum reviews to show.
- Edit the message if you want, then set the corner, pages and timing (design, placement and timing).
- Check the preview and click Save.
The popup reads your latest published Judge.me reviews and refreshes every hour. Reviews you’ve unpublished or hidden in Judge.me don’t show, and long reviews are shortened to fit the card.
Is the Judge.me private token safe to share?
Treat it like a password. Judge.me’s own help page says the private token grants read and write access to your data and should only be used on the server side. It also says you can’t regenerate it yourself; if it’s ever exposed, you contact Judge.me support for a new one.
In Sam FOMO, the token stays on our server and is never sent to your storefront. The popup on your store gets the review text, not the token. Still, only paste it into apps you trust, and never into theme code or a public file.
How do you use Shopify product ratings instead?
Follow the same steps, but under Review source choose Shopify product ratings. There’s no token to paste. The popup shows one card per rated product, with the average rating and how many customers rated it, and leaves out products below your minimum rating. If no popups show, your review app may not fill in the standard rating fields; check with its support.
What should the review popup say?
Let the review do the talking. The default message in Sam FOMO is “{{reviewer_name}} rated {{product_name}} {{rating}}/5”, with “{{stars}} {{review_body}}” on the line below. That works for both sources, because a Shopify rating shows as “120 customers rated…” in the name slot.
If you rewrite it, keep these rules:
- Keep the reviewer’s words in the quote. Write your own copy around it, not inside it.
- Don’t add claims the data can’t back. “Our best-rated product” needs to be true across your catalog, not just in the popup feed.
- Keep it short. Two lines read faster than four on a phone.
Here are some before-and-after examples:
| Risky | Honest |
|---|---|
| “Everyone loves this shirt!” above one 5-star review | “Rob rated Linen Shirt 5/5” with his quote |
| “All our reviews are 5 stars” on a feed filtered to 5 stars | “Recent 5-star review” |
| A review quote trimmed to change its meaning | The start of the review, as written |
Which minimum rating and placement should you start with?
Start with 4 stars and up, on product and collection pages. That keeps the feed positive without making every card look identical. If you have plenty of reviews and want a more representative mix, try 3 stars and up and see whether shoppers still click.
A few setup tips:
- Cap the count. A shorter list of strong, recent reviews beats a long feed shoppers never finish.
- Pick a quiet corner. Keep the popup away from the add to cart button and your chat widget, especially on phones.
- Space it out. Use a longer gap between popups if you also run a sales feed in the same corner.

How do you know if review popups are working?
Compare clicks and closes, not just impressions. In Sam FOMO, Analytics shows impressions, clicks and click-through rate, and Performance by popup type breaks them down per type, including close rate (analytics guide).
If shoppers close review popups more than they click them, change one thing at a time: the pages, the gap between popups, or the minimum rating. Then check your conversion rate in Shopify over a few weeks, since one week of data can mislead.
Before you turn it on, run through this checklist:
- Every review comes from a real customer and appears exactly as written.
- Your product page shows all reviews, including low ratings.
- The popup copy doesn’t claim the feed is all your reviews.
- Your Judge.me private token lives only in a trusted app, never in theme code.
- The popup sits away from the buy button and doesn’t stack with three other signals.
Frequently asked questions
What is a review popup?
It is a small notification that shows a customer review or a product rating while a shopper browses, for example "Rob rated Linen Shirt 5/5" with a short quote. It brings reviews that sit at the bottom of a product page into view on other pages.
Can I show Judge.me reviews as popups on Shopify?
Yes. Judge.me offers an API that other apps can read with your private API token. In Sam FOMO you create a Product Reviews notification, pick Judge.me reviews as the source and paste the token from your Judge.me admin under Settings > Integrations > View API tokens.
Is it OK to show only 4 and 5 star reviews in a popup?
A popup is a featured selection, not your review section. Keep every review on the product page, do not hint that the popup shows all your reviews, and do not hide bad reviews from the main list. The FTC rule on consumer reviews treats hiding negative reviews while implying you show them all as review suppression. This is general information, not legal advice.
What if I use a review app other than Judge.me?
Many review apps write each product's average rating and rating count to Shopify's standard product rating fields. Sam FOMO can read those fields and show a popup such as "120 customers rated Linen Shirt 4.6/5". It shows the product rating, not individual review text.
How fast do new reviews appear in the popup?
Sam FOMO refreshes review data every hour, for both Judge.me reviews and Shopify product ratings. A review that was just published can take up to about an hour to show up.
