7 Best WordPress Review Plugins in 2026 (Tested and Compared)

If you want more reviews on your WordPress site, you have already run into the same problem most site owners hit: there are dozens of review and rating plugins on WordPress.org, they all claim to be the best, and it is not obvious which one actually fits what you are trying to do.

The problem is that "WordPress review plugin" covers at least four completely different jobs. Some plugins collect original customer or visitor reviews on your site. Others add a star-rating widget to your blog posts so readers can rate your content. A third group focuses on structured data, generating the JSON-LD markup that lets Google display star snippets in search results. And a fourth group pulls your existing Google, Facebook, or Yelp reviews into WordPress so visitors can see your social proof on the site itself.

I reviewed more than a dozen plugins across all four categories. I installed five of the seven final picks in a clean WordPress sandbox for hands-on admin testing, and checked the remaining two against their official plugin documentation and vendor materials. Every pricing page was verified live before writing. The seven plugins below cover every realistic buyer scenario, from a free testimonials page to a WooCommerce store automating post-purchase review emails.

How I evaluated these plugins

I installed and activated each plugin on a clean WordPress 7.0 environment (PHP 8.3) and worked through the admin setup: settings panels, review form configuration, schema output options, moderation controls, and page-builder or shortcode integration. For each plugin I also checked the WordPress.org listing (active installs, rating, last update date), the vendor pricing page, and the official documentation.

Criteria I used:

• Setup speed and clarity of the admin UI
• Free-version usefulness (can a real site use this without paying?)
• Review collection flow (submission form, moderation, spam protection)
• Star-rating options and display flexibility
• Schema and rich-results support (JSON-LD vs microformat, schema type coverage)
• WooCommerce product review support where relevant
• Pricing fairness and what the paid upgrade actually adds
• Update cadence and WordPress version compatibility

Quick comparison: 7 best WordPress review plugins

The 7 best WordPress review plugins in 2026

1. Site Reviews: best free dedicated review plugin for any site

Site Reviews is the most feature-complete free WordPress review plugin I tested. It works similarly to Amazon, TripAdvisor, or Yelp reviews: visitors submit a star rating and written review, you moderate submissions, and the approved reviews appear on whichever post, page, or WooCommerce product you assign them to.

The plugin creates a dedicated custom post type for reviews, which means your reviews are not mixed in with posts or pages. You can assign reviews to any category, post, page, custom post type, or user account. The Gutenberg block editor gets six custom blocks (Latest Reviews, Single Review, Product Rating, Rating Summary, Product Reviews, Review Form), and native page-builder elements cover Avada Builder, Breakdance, Bricks, Divi 5, Elementor, Flatsome, and WPBakery.

What stood out in hands-on testing was the JSON-LD schema setup. The schema output is a first-class settings panel in the free version, not a paid upsell. You configure it in the Settings tab under JSON-LD Schema Settings, where you pick the default schema type, name, description, URL, image, address, and phone number.

Site Reviews also has the most comprehensive spam protection of any free review plugin I tested: Honeypot, six CAPTCHA options (Cloudflare Turnstile, FriendlyCaptcha, hCaptcha, Procaptcha, reCAPTCHA v2 Invisible, and reCAPTCHA v3), Akismet, keyword Blacklist, and per-IP/email/username review limits. That five-layer stack matters a lot when you open a public review form to anonymous visitors. If you are thinking about how to handle spam on user-generated content more broadly, the best WordPress anti-spam plugins post covers the broader ecosystem.

WooCommerce and SureCart product-review integrations ship in the free version. A WooCommerce settings tab appears in the admin after you install WooCommerce, letting you attach Site Reviews' review form and display to product pages directly.

Practical strengths:

• JSON-LD schema output in the free version, not behind a paywall
• Five-layer spam protection (best in this roundup for a free tier)
• WooCommerce and SureCart integration included free
• Six Gutenberg blocks plus native Elementor, Divi 5, Bricks, and Breakdance elements
• CSV importer to bring in reviews from other sources
• REST API for headless or remote review access
• Bayesian ranking for sorting pages by review score in WP_Query
• 60,000+ active installs, 4.9/5 rating across 370 reviews
• Version 8.0.12 released June 23, 2026; tested up to WordPress 7.0

Practical limitations:

• Pro pricing is in euros (EUR 89/yr for one site, EUR 179/yr for up to three sites, EUR 289/yr for up to six sites), which can catch international buyers off-guard
• Custom review form fields beyond the defaults, a theme and carousel builder, review image galleries, and scheduled notification emails all require the paid Premium plan

Pricing: Free on WordPress.org. Site Reviews Premium from EUR 89/yr (1 site), EUR 179/yr (up to 3 sites), EUR 289/yr (up to 6 sites). 14-day money-back guarantee. Available at niftyplugins.com.

WordPress.org: wordpress.org/plugins/site-reviews

Best for: Any WordPress site that needs a free, full-featured review system for posts, pages, or WooCommerce products, and wants JSON-LD schema and solid spam protection without paying for a premium plan.

2. WP Customer Reviews: best fully free testimonials plugin

WP Customer Reviews is the most widely used entirely-free WordPress review plugin. There is no paid tier, no upgrade prompt in the admin, and no feature gate. Everything ships in the single free installation.

The plugin is designed for collecting testimonials and customer feedback for a business or its products. You place a review submission form and review display on any page or post via shortcodes. All submissions go into a moderation queue by default: nothing appears publicly until you approve it. Admins can also write inline responses directly below individual reviews.

I tested the admin settings in a WordPress 7.0 sandbox. The Display Settings tab handles pagination and a "Powered by WP Customer Reviews" footer toggle. The Form Settings tab controls which fields appear (name, email, title, content, city, state, website) and which are required. The How To Use tab documents every shortcode with parameter options, including POSTID="ALL" to show reviews from all posts together on one page.

The schema output uses Schema.org microformat markup, not JSON-LD. Microformats are still parsed by Google, but the ecosystem is moving toward JSON-LD as the standard. If schema-rich SERP star snippets are a priority, Site Reviews or YASR are better fits. WP Customer Reviews is best when the goal is simply to collect and display testimonials on a service or business page.

Practical strengths:

• Completely free, no paid tier, no nags
• All submissions moderated by default before going public
• Admin response feature for replying to individual reviews
• Schema.org microformat output for basic structured data
• Shortcodes work on any page, post, or widget area
• Multiple review types: business reviews and product reviews
• Multisite compatible
• 20,000+ active installs; version 3.8.1 released June 17, 2026; tested up to WordPress 7.0

Practical limitations:

• Microformat schema, not JSON-LD (less alignment with Google's current recommended format)
• No WooCommerce-specific integration; the form has to be placed on a specific page via shortcode, not auto-attached to product pages
• Admin UI is older-style WordPress with no Gutenberg blocks or page-builder elements
• Rating of 4.3/5 across 526 reviews is lower than most others in this roundup, often because of styling questions the plugin intentionally leaves to themes

Pricing: Free. No paid tier.

WordPress.org: wordpress.org/plugins/wp-customer-reviews

Best for: Small businesses or service sites that want a simple, completely free way to collect moderated testimonials on a specific page, without WooCommerce and without schema complexity.

3. kk Star Ratings: most popular free star-rating widget

kk Star Ratings is the highest-install pure star-rating plugin for WordPress with 70,000+ active installations. It does one thing: add a five-star rating widget to posts, pages, and custom post types, let visitors vote, and output JSON-LD structured data so Google can show star snippets for those pages in search results.

I activated the plugin on a WordPress 7.0 sandbox. On first load it shows a Freemius opt-in screen. Skipping it takes you directly to the settings. The interface has four tabs: General (enable/disable globally), Appearance (star count, size, gap, display position with six position radios), Rich Snippets (a Status toggle for JSON-LD schema output plus a schema type selector), and the FeedbackWP Premium upsell sidebar.

The key buyer decision with kk Star Ratings is that it is a rating widget, not a review plugin. Visitors can click stars to vote, and those votes produce an average rating with a vote count. There is no text submission form, no moderation queue, and no per-visitor review content. It is the right tool for a publisher who wants to let readers rate individual blog posts and have those ratings appear as star snippets in Google search results, and nothing more.

For a comparison of other schema-related WordPress tools, see the best WordPress schema plugins roundup, which covers the broader schema and structured data plugin landscape.

Practical strengths:

• Largest install base of any pure star-rating plugin (70,000+)
• JSON-LD rich snippets included free
• Easy position controls (before content, after content, or both)
• Restrict votes by IP address to reduce vote stuffing
• Allow or restrict voting on archive pages
• Works on custom post types
• Version 5.4.10.5 released June 18, 2026; tested up to WordPress 7.0

Practical limitations:

• Freemius first-load opt-in before reaching settings (a common frustration cited in 1-star reviews)
• Persistent "Go Premium" link in the plugin list and sidebar nag in settings
• No text review form, no moderation, no visitor review content
• No WooCommerce-specific product rating integration
• Rating of 3.9/5 across 171 reviews (lowest in this roundup), mainly from users expecting more editorial review features

Pricing: Free on WordPress.org. FeedbackWP Premium add-on available via feedbackwp.com.

WordPress.org: wordpress.org/plugins/kk-star-ratings

Best for: Blog publishers who want a visitor star-rating widget on posts and need JSON-LD structured data for SERP star snippets, without the complexity of a full review-collection system.

4. YASR (Yet Another Stars Rating): best free star-rating plugin with multi-criteria reviews

YASR is the strongest free option when you need both a star-rating widget and multi-criteria reviews, plus granular schema-type control. Where kk Star Ratings gives you a single rating per post, YASR lets you build a multi-criteria set with individual star widgets for separate dimensions (for example: performance, value, ease of use), combine them into an overall score, and pick which of 17 Schema.org itemTypes drives your structured data output.

I tested YASR on WordPress 7.0. After skipping the Freemius opt-in, the settings panel is well organized. The General Settings tab includes an Auto Insert section, a starred archive-sort option, and a visitor permissions toggle (logged-in only, or logged-in plus anonymous). The Manage Multi tab is a drag-and-drop multi-criteria set builder. The Structured Data Options section is the standout: a 17-itemType dropdown (BlogPosting, Book, Course, Episode, Event, Game, LocalBusiness, MediaObject, Movie, MusicPlaylist, MusicRecording, Organization, Product, Recipe, SoftwareApplication, CreativeWorkSeason, CreativeWorkSeries), plus publisher name, publisher logo, and a built-in inline warning that BlogPosting schema will not produce star snippets in Google per the 2019-09-16 Google policy update.

That inline policy warning is useful for anyone who would otherwise waste time configuring BlogPosting schema expecting stars in the SERP and getting nothing.

Practical strengths:

• 17 Schema.org itemTypes selectable from a dropdown, including Product, LocalBusiness, Recipe, SoftwareApplication, and Event
• Multi-set builder for multi-criteria reviews (rate individual dimensions separately)
• Inline Google policy warning for BlogPosting schema (will not produce SERP stars)
• Visitor voting (logged-in or anonymous) plus author-only rating option
• Stats dashboard and rankings (top-rated posts) built in
• REST API support
• Works on WooCommerce product post type
• 4.7/5 rating across 323 reviews

Practical limitations:

• Freemius first-load opt-in (same friction as kk Star Ratings)
• Last update was April 2025, so the "tested up to 6.8.5" badge lags behind the current WordPress 7.0 stable release. YASR installed and ran cleanly on WP 7.0 in my sandbox, but the badge gap is worth noting when evaluating update cadence
• Install base of 10,000+ is smaller than kk Star Ratings (70,000+)

Pricing (verified June 26, 2026): Free on WordPress.org. YASR Pro: Annual $47.88/yr (1 site), $95.88/yr (5 sites), $143.88/yr (30 sites). Monthly $4.99/mo, $9.99/mo, $14.99/mo. Lifetime $149.99 (1 site), $289.99 (5 sites), $439.99 (30 sites). Pro adds user reviews and testimonials, custom rankings, 20+ review display themes, custom theme uploads, and priority email support.

WordPress.org: wordpress.org/plugins/yet-another-stars-rating / Vendor: yetanotherstarsrating.com

Best for: Publishers who want multi-criteria reviews and precise schema-type control across 17 itemTypes, with a free version that covers both without needing to pay.

5. Schema Engine AI: best AI-powered multi-criteria review plugin

Schema Engine AI (previously known as Review Schema, by RadiusTheme) is the most technically advanced review plugin in this roundup. It combines a proper multi-criteria review form (rating score, pros and cons, image uploads, GDPR consent checkbox, reCAPTCHA v3 spam protection) with an AI-powered schema generator that uses your own OpenAI, Anthropic Claude, or Google Gemini API key to produce structured data automatically.

The plugin ships with a Setup Wizard that specifically addresses one of the most common WordPress schema problems: duplicate schema from conflicting plugins. The wizard offers explicit toggles to disable the default schema output from WooCommerce, EDD, SureCart, Rank Math, and Yoast SEO. That kind of proactive conflict prevention is rare.

I tested Schema Engine AI on WordPress 7.0. The admin loads as a React single-page app under the "SchemaEngine AI" menu. The Settings panel has sidebar tabs for Identity (site info, social profiles), Generation (post-type mapping, archive page settings), E-Commerce, and AI Settings (provider selector with OpenAI, Anthropic Claude, and Gemini, plus an API Key input). The main settings include an "Enable Schema (JSON-LD)" master toggle and a separate "Enable Review" toggle that activates the review-collection features.

AI generation is triggered manually. The plugin does not send content to any external server unless you click Generate. For broader SEO plugin context, the top free SEO plugins for WordPress roundup covers how Rank Math and Yoast approach schema.

Practical strengths:

• Multi-criteria review form with pros and cons lists and image upload in the free version
• AI schema generation via OpenAI, Claude, or Gemini (bring your own API key; content is never sent to RadiusTheme servers)
• Real-time rich results validator and Google SERP preview built into the editor
• Setup Wizard with explicit conflict-prevention toggles for WooCommerce, Rank Math, Yoast SEO, and others
• GDPR consent checkbox and reCAPTCHA v3 in the review form
• AI FAQ generation with Gutenberg block (accordion and tab layouts, JSON import and export)
• 4.8/5 rating across 25 reviews; version 3.0.4 released June 22, 2026; tested up to WordPress 7.0

Practical limitations:

• Most e-commerce schema types (Product, Recipe, Course, Restaurant, JobPosting, VehicleListing, VacationRental, TVSeries) are Pro-only. The free tier covers content and editorial schema and the multi-criteria review form, but not full WooCommerce product review schema end-to-end
• AI features require a third-party LLM API key (billed separately by the LLM provider)
• Smaller review count (25 reviews) compared to Site Reviews or CusRev

Pricing (verified June 26, 2026): Free on WordPress.org. Pro: Annual $34/yr (1 site), $104/yr (10 sites), $139/yr (unlimited sites). Lifetime $89 (1 site), $149 (10 sites), $199 (unlimited sites). 30-day money-back guarantee.

WordPress.org: wordpress.org/plugins/review-schema / Vendor: schemaengineai.com

Best for: Sites that want multi-criteria review forms with AI-assisted schema generation and SERP preview, especially when Rank Math, Yoast, or WooCommerce are also active and causing schema conflicts.

6. Customer Reviews for WooCommerce (CusRev): best WooCommerce review plugin

Customer Reviews for WooCommerce (CusRev) is the most capable WooCommerce-specific review plugin I evaluated. It handles everything after a purchase: automated review reminder emails, multi-item review forms (customers rate several products in one submission), photo and video uploads, JSON-LD product schema, a Questions and Answers section per product, and automatic discount-coupon generation in exchange for a review.

The install base backs it up: 80,000+ active installations with a 4.8/5 rating across 1,523 reviews is unusually strong for a plugin that only works with WooCommerce. If you are setting up a WooCommerce store from scratch, the guide to setting up a WooCommerce store covers the full configuration process.

I verified that CusRev activates cleanly on a WordPress install and includes a thoughtful safeguard: the plugin automatically pauses automated email reminders when it detects the site is a duplicate or staging environment. This prevents accidental duplicate review emails when a live store is cloned for testing. The WooCommerce product review admin and email automation flows were reviewed against the official plugin documentation and vendor materials, as the combined WooCommerce plus CusRev install requires more memory than the testing environment provides.

Practical strengths:

• Automated post-purchase review reminder emails with customizable sending delays
• Multi-item aggregated review forms (customers review multiple recent purchases in one step)
• Photo and video upload by customers (user-generated content for product pages)
• JSON-LD structured data markup for product reviews including review images
• Google Shopping XML feed generation with review integration for Product Listing Ads
• Questions and Answers section per product with admin moderation
• Discount coupons offered as review incentives, with badge marking incentivized reviews
• Gutenberg blocks plus shortcodes for grid, slider, and list review display
• Import and export via CSV; 33 languages; trust badges; analytics
• 80,000+ active installs; version 5.113.0 released June 21, 2026; tested up to WordPress 7.0

Practical limitations:

• Requires WooCommerce; not usable for a blog, service, or non-product site
• Professional (paid) plan is per domain, so an agency with five stores needs five licenses
• Advanced email template editor, custom review form questions, social-media auto-share (Facebook, Instagram), and removing CusRev attribution from emails are paid-only
• No money-back guarantee advertised on the pricing page

Pricing (verified June 26, 2026): Free on WordPress.org. Professional plan: $59.99 + VAT per year (billed annually, saves 37% vs monthly), $7.99 + VAT per month. One license per domain, transferable between domains.

WordPress.org: wordpress.org/plugins/customer-reviews-woocommerce / Vendor: cusrev.com/business

Best for: WooCommerce store owners who want to automate post-purchase review collection, display photo and video reviews on product pages, and feed product ratings into Google Shopping.

7. Widgets for Google Reviews (Trustindex): best plugin for pulling in Google Reviews

Widgets for Google Reviews by Trustindex solves a different problem than the other six plugins in this list. Instead of collecting new reviews on your WordPress site, it pulls your existing Google reviews (and on paid plans, Facebook, Yelp, Trustpilot, TripAdvisor, and 130+ other platforms) into a widget you embed anywhere on your site.

This matters for local businesses and service providers who already have strong Google review profiles and want visitors to see that social proof without leaving the site to check Google Maps. The free version lets you display up to 10 Google reviews in one widget, choosing from 40+ layout styles. No Google Places API key is required: the connection flow uses Trustindex's own proxy, so you enter your Google Business URL or Place ID and Trustindex handles the data retrieval.

I tested the plugin on WordPress 7.0. After installation and activation through the plugins screen, the plugin loaded its own onboarding screen with a "Connect Google" heading and a simple form for connecting a Google Business profile. The widget display and layout options were reviewed via the official WordPress.org plugin screenshots, which show the full range of available styles.

Practical strengths:

• 900,000+ active installs (largest install base of any review plugin on WordPress.org)
• 4.9/5 rating across 2,588 reviews
• No Google API key required (Trustindex proxies the Places API)
• 40+ widget layouts and 25+ pre-designed styles
• Reviews stored in WordPress database (no frontend API calls per page load)
• Blocks for Gutenberg, Elementor, Page Origin, Beaver Builder, WPBakery, Divi, and Classic editor
• Filter reviews by minimum star rating; hide specific reviews; anonymize reviewer names
• 49 language strings; multisite compatible
• 7-day free trial and 30-day money-back guarantee on paid plans
• Version 13.3.1 released June 24, 2026; tested up to WordPress 7.0

Practical limitations:

• Free tier caps at 10 reviews and 1 widget at a time
• Multi-platform access (Facebook, Yelp, Trustpilot, and the other 130+ sources) requires a paid plan
• Automated review-invitation system, AMP support, multiple business locations, and removing the Trustindex branding are all paid-only
• Review data routes through Trustindex's servers (acceptable for displaying public reviews, but worth knowing for data-path transparency)

Pricing (verified June 26, 2026): Free on WordPress.org. Trustindex Pro: Single Plan $65/yr (1 domain), Pro Plan $125/yr (5 domains), Ultimate Plan $349/yr (unlimited domains). All paid plans include unlimited widgets, unlimited views, unlimited reviews, access to 133 review platforms, and a 7-day free trial. 30-day money-back guarantee. Add-ons: automatic AI review replies $29/source/year, Google Business SEO Analysis $29/source/year.

WordPress.org: wordpress.org/plugins/wp-reviews-plugin-for-google / Vendor: trustindex.io

Best for: Local businesses, restaurants, or service providers with an established Google review profile who want to display those reviews on their website without managing a separate on-site review system.

How to choose the right WordPress review plugin

The right pick depends on what you are actually trying to accomplish.

You want visitors to leave reviews directly on your site. Site Reviews is the strongest free option here. It works for blogs, service pages, WooCommerce products, and SureCart stores. If you specifically need a business testimonial page with zero cost and no configuration complexity, WP Customer Reviews is the simpler choice.

You want star ratings on blog posts that appear in Google search results. kk Star Ratings is the highest-install option for a single rating per post. YASR is the better pick if you want multi-criteria ratings or need to pick from 17 schema itemTypes. Both output JSON-LD for rich snippets. Use YASR if schema type matters to you (Product, Event, LocalBusiness, Recipe, etc.); use kk Star Ratings if you just need a quick voter widget on posts.

You want AI-assisted schema generation plus a multi-criteria review form. Schema Engine AI is the only plugin in this lineup that combines both. The free tier covers content and editorial use cases. If Product or WooCommerce schema is the goal, the Pro tier is needed.

You run a WooCommerce store. CusRev is the purpose-built choice. It handles post-purchase automation, photo and video reviews, and Google Shopping XML. Site Reviews also works with WooCommerce for stores that want a closer-to-native review experience without email automation.

You already have Google reviews and want to display them on your site. Widgets for Google Reviews by Trustindex handles this without requiring an API key. If your review sources include Facebook, Yelp, or Trustpilot, a paid Trustindex plan unlocks all 133 platforms.

For a broader look at what plugin categories every WordPress site should consider covering, the top free WordPress plugins roundup covers the essential categories.

FAQ

What is the best free WordPress review plugin?

Site Reviews is the best free review plugin for most sites. It includes JSON-LD schema output, a five-layer spam protection stack, WooCommerce and SureCart integration, Gutenberg blocks, and native elements for Elementor, Divi 5, and Bricks, all in the free version. WP Customer Reviews is the better choice if you need a simple business testimonial page and want something with zero pricing at any level.

Do WordPress review plugins help with SEO?

Yes, if the plugin outputs valid JSON-LD structured data with the correct schema type. Plugins that generate valid aggregate rating markup can qualify your pages for star snippets in Google search results, which typically improves click-through rate. However, Google has strict rules: not all schema types qualify for star snippets in search. BlogPosting schema, for example, does not produce stars in the SERP. YASR, Schema Engine AI, and Site Reviews all support the schema types that Google recognizes for rich results.

Which WordPress review plugin works best with WooCommerce?

Customer Reviews for WooCommerce (CusRev) is built specifically for WooCommerce stores. It automates post-purchase review emails, supports photo and video uploads, outputs JSON-LD product schema, and generates Google Shopping XML feeds. Site Reviews and Schema Engine AI Pro also support WooCommerce product reviews, but CusRev is the dedicated specialist.

Can I display Google reviews on my WordPress site?

Yes. Widgets for Google Reviews by Trustindex is the most popular option, with 900,000+ active installs. The free version shows up to 10 Google reviews in one widget with no API key required. Paid plans add more reviews, multiple widgets, and access to Facebook, Yelp, Trustpilot, TripAdvisor, and 130+ other review platforms.

What is the difference between star ratings and review plugins?

A star-rating plugin (like kk Star Ratings or YASR) adds a clickable rating widget to posts and pages so visitors can vote. Votes produce an average score and vote count, and that data can feed JSON-LD structured data. There is usually no text submission, no moderation, and no review content. A review plugin (like Site Reviews, WP Customer Reviews, or CusRev) collects full written reviews: visitors submit a star rating plus a text review, and an admin moderates before publishing. Some plugins combine both functions.

Are review plugins safe for a public-facing WordPress site?

The main risk is spam submissions on a public review form. Site Reviews ships five layers of spam protection (Honeypot, six CAPTCHA options, Akismet, Blacklist, and review limits) in the free version. Schema Engine AI includes reCAPTCHA v3 in its review form. WP Customer Reviews moderates all submissions by default, so spam never appears publicly without admin approval. Plugins that only add a star-rating widget (kk Star Ratings, YASR) have no public text submission, so their spam surface is smaller.

Conclusion

The best WordPress review plugin depends on what you need reviews to actually do.

If you want a complete, free, first-party review system with JSON-LD schema and spam protection built in, Site Reviews is the strongest pick in 2026. If you just need a testimonials page with zero cost and no paid tier at all, WP Customer Reviews handles it cleanly. For star ratings on blog posts with JSON-LD rich snippets, kk Star Ratings is the simplest and YASR is the more capable option. For AI-powered schema and multi-criteria review forms, Schema Engine AI is the standout choice. For WooCommerce stores that want automated review emails and photo and video UGC, CusRev is purpose-built for that. And if your goal is displaying your existing Google reviews on the site, Widgets for Google Reviews by Trustindex covers it without requiring an API key.

All seven plugins have usable free versions. Most have paid tiers that add automation, advanced schema types, or extra display options, but none of them require a paid plan for the core review or rating workflow.
