The most installed review software on US business websites is Trustindex, on 22,848 sites, which shows your Google and Facebook reviews on your own site. For online stores it is Judge.me, on 13,205. About 5% of US business sites (56,292 of 1.1 million) run any review tool at all. Review management software roundups usually mix two different jobs into one list: collecting reviews of a business (any business, any industry) and collecting reviews of individual products (ecommerce specifically). Stackra checked adoption across 1.1 million verified US small business websites, and the split shows up clearly in the data.

What businesses actually install

Ranked by real detected installs.

Two different jobs, and most of this list is actually the ecommerce one

Judge.me, Yotpo, Loox, Stamped, and Okendo, five of the eight tools here, are ecommerce product-review apps, mostly built for Shopify. They collect star ratings and photo reviews on individual product pages, and only make sense if you run a store with individual products to review. If you are not running an online store, none of these five apply to you at all, regardless of how often they show up in "best review software" rankings.

Trustindex, Rich Plugins and Trustpilot: the tools for any business, not just stores

Trustindex leads real adoption by a wide margin and works for any business type: it pulls in your existing Google and Facebook reviews and displays them on your site, rather than asking customers to leave a new, separate review. Trustpilot works differently, it is its own independent review platform that customers review you on directly, with a public profile page separate from your site. Rich Plugins Reviews does the same job as Trustindex for WordPress sites and is the third most installed tool here. Trustindex is the lower-effort pick if you already have Google reviews worth showing off; Trustpilot is the better pick if you want a third-party-verified reputation page you can point people to.

If you run an ecommerce store specifically

Judge.me is the most installed of the five ecommerce-focused tools and still has a free plan; its one paid plan is $15 a month (Judge.me pricing page, November 2026). Yotpo and Stamped both bundle reviews with loyalty-program features, worth it if you want both in one tool. Loox is specifically built around photo and video reviews, useful if visual proof matters more than star ratings for what you sell.

The rules on reviews

Whatever tool you use, the US Federal Trade Commission's rule on consumer reviews and testimonials, finalized in August 2024, sets the limits. It bans fake reviews (including AI-written ones from people who never used you), paying for reviews that must be positive or negative, undisclosed reviews from your own staff, and suppressing negative reviews through threats or by implying the reviews you show are all of them. Showing your real Google or Facebook reviews on your site, which is what Trustindex and Rich Plugins do, is fine.

How we got this data
