Biggest Movers
Expert Insight: Review & Rating Platforms Market Share & Momentum
Four tools hold about two thirds of this category, and they are two different products: Shopify review apps and review platforms.
Judge.me leads with about 355,000 of the 1.76M domains where we detect a review or rating tool, roughly 20%, ahead of Klaviyo Reviews, Trustindex and Trustpilot at 13% to 16% each. The four hold about 65% between them, but they don't sell the same thing: Judge.me and Klaviyo Reviews collect product reviews inside Shopify stores, while Trustindex and Trustpilot display reviews that live somewhere else, on Google or on Trustpilot's own site. Below them, trust badges that host no reviews at all share the table.
Shopify apps on one side, review platforms on the other
Judge.me about 20%, Klaviyo Reviews 16%, Trustindex 15.5%, Trustpilot 13%, then a drop to TrustedSite at about 5% and nothing else above 3.5%. Judge.me, Klaviyo Reviews, Loox, Yotpo and Stamped are Shopify review apps and hold about 43% of the table between them. Klaviyo Reviews has no profile of its own, and its script can load on any store running Klaviyo's Shopify app embed, so read that row as an upper bound. Rich Plugins Reviews, at about 3%, is the WordPress widget that displays a business's Google reviews, which puts it with Trustindex rather than with the Shopify apps.
The big 90-day gains are badges we only just started detecting
Over the latest 30 days nothing gains at scale: Google Customer Reviews leads with about 700 domains net and the Heureka widget adds about 500. Over 90 days TrustedSite added about 75,000, roughly four fifths of its footprint, and DMCA Badge and the two TripAdvisor rows each netted most of theirs, which is our detection set expanding rather than adoption. TrustedSite is a trust badge that GoDaddy's site builder and managed WordPress hosting switch on for their customers, so even its real installs are rarely a purchase. Among tools that actually show reviews, Trustindex added about 13,000 over 90 days and Judge.me about 9,000.
Trustpilot's 90-day loss is mostly our crawl
Trustpilot lost about 9,900 domains net over 30 days and about 75,000 over 90, the largest decline in the category on both windows. Most of the 90-day drop fell in a few weeks when our crawl stopped registering many sites' scripts at once, across many technologies, so it measures lapsed signals more than cancelled accounts. Trustpilot's rule also counts the DNS verification record a business adds when it claims its domain, which proves a Trustpilot account rather than a widget on the page, though that clause carries only a small part of the count. Category turnover runs about 5.8% a month.
Loox and Yotpo are the incumbents falling on both windows
Loox lost about 2,200 domains net over both 30 and 90 days and Yotpo Reviews about 2,000 over each, while Judge.me, Klaviyo Reviews and Trustindex are up over 90 days and only slightly down over 30. Of the four large Shopify apps, the two still up over 90 days are the free one and the bundled one: Judge.me has a free plan, and Klaviyo Reviews comes with an email tool many stores already pay for. That is a pattern in net counts, not measured switching. One caveat: a widget that loads only on product pages or after a consent click can be missed, so product-page review apps may be undercounted.

Start from your own size, industry and primary use case rather than from share. Judge.me Reviews Shopify App, Klaviyo Reviews and Trustindex are the three we detect most often in this category, which tells you what is common, not what fits you.

Common questions about reviews & ratings software, answered with real data.
What is review and rating software?
Review software collects customer reviews and star ratings and shows them on a website, usually as product-page widgets, star badges and review carousels. Some tools collect the reviews themselves, like Judge.me and Loox inside Shopify stores. Others display reviews hosted elsewhere, like Trustpilot's TrustBox widgets or Trustindex's Google-review widgets. We detect a review or rating tool on about 1.76 million live websites across 100 tools.
Which review platform has the largest market share?
Judge.me. Its Shopify app runs on roughly 355,000 of the 1.76 million live websites where we detect a review tool, about 20% of the category. Klaviyo Reviews is second at about 16%, Trustindex third at about 15.5% and Trustpilot fourth at about 13%. Those four hold about two thirds of the category between them, and nothing else clears 6%.
What are the most popular review apps for Shopify?
By live websites, the Shopify review apps we detect most are Judge.me (about 355,000 domains), Klaviyo Reviews (about 278,000), Loox (about 58,000), Yotpo Reviews (about 49,000) and Stamped (about 19,000). Together they hold about 43% of the review category. Treat the Klaviyo Reviews figure as an upper bound, because its script can load on any store running Klaviyo's Shopify app embed.
What's the difference between Judge.me and Klaviyo Reviews?
Judge.me is a standalone Shopify review app with a free plan, and the most detected review tool we track, on about 355,000 domains. Klaviyo Reviews is the review feature inside Klaviyo, the email and SMS platform, so it suits stores that already send email through Klaviyo. We count it on about 278,000 domains, an upper bound, since its script can load wherever Klaviyo's Shopify app embed does.
What's the difference between Trustpilot and Trustindex?
Trustpilot hosts reviews on its own public site and lets businesses embed them through TrustBox widgets; we detect it on about 235,000 domains. Trustindex is best known for widgets that pull a business's reviews from Google and other platforms onto its own website, and runs on about 273,000 domains. Choose Trustpilot if you want an independent review profile, Trustindex if your reviews already live on Google.
How much does review software cost?
Entry pricing is low. At the time of writing Judge.me has a free plan and a paid Awesome plan at $15 a month. Trustpilot has a free business plan, with paid tiers from about $99 a month and Plus and Premium plans at about $319 and $799 a month per domain, billed annually. Enterprise review platforms such as Bazaarvoice and PowerReviews quote prices on request.
Is Trustpilot losing customers?
Fewer than our raw numbers suggest. Trustpilot lost about 9,900 domains net over the latest 30 days and about 75,000 over 90, the largest decline in the review category. Most of the 90-day drop came in a few weeks when our crawl stopped registering many sites' scripts at once, across many technologies, so it measures lapsed signals more than cancellations. Trustpilot still runs on about 235,000 domains, fourth in the category.
How do I show Google reviews on my website?
Use a widget that pulls reviews from your Google Business Profile. Trustindex is the most detected tool that does this, on about 273,000 domains. On WordPress, Rich Plugins Reviews (the Widget for Google Reviews plugin) runs on about 58,000. Google Customer Reviews is a different thing: Google's opt-in survey and badge for online merchants, which collects seller ratings rather than displaying your Business Profile reviews.
Is TrustedSite a review platform?
Not really. TrustedSite is a trust badge, a certification seal that tells shoppers a site has been checked, rather than a tool for collecting customer reviews. It sits fifth in our review category with about 94,000 domains, and most of those sites didn't choose it: GoDaddy's website builder and managed WordPress hosting switch it on for their customers. Its 90-day gain of about 75,000 domains is new detection, not adoption.
Which review tools are growing fastest?
Very little grows over 30 days: Google Customer Reviews leads with about 700 net domains, followed by the Heureka widget at about 500. Over 90 days Trustindex added about 13,000 and Judge.me about 9,000, the largest gains among tools that collect or display reviews. The bigger 90-day numbers, TrustedSite, DMCA Badge and two TripAdvisor rows, are mostly badges and widgets we only began detecting in that window.
