You want customer testimonials on your WordPress site. Simple request. But the plugin ecosystem is a minefield — bloated options that slow your site, flimsy ones that break on updates, and a few that actually work.
This guide cuts through it. We've tested the main options and ranked them honestly for small business owners who care about results, not feature lists.
Before comparing options, here's what actually matters:
SocialProof isn't a WordPress plugin — it's a testimonial platform with an embed code that works on any website, including WordPress. You paste a `<script>` tag into a Custom HTML block (or any widget area), and your testimonial carousel or grid appears. This means no plugin update headaches, no WP compatibility issues, ever.
Where SocialProof stands out: it handles collection too. You share a link, customers submit testimonials directly, and they appear in your widget automatically. No copy-pasting from emails, no manual uploads.
Strong Testimonials has been around since 2014 and has 100,000+ active installations. It's genuinely good — native WordPress custom post type, Gutenberg block, shortcode support, and a collection form that works within WordPress. If you want everything managed inside WP admin, this is the best choice.
Does one thing: shows testimonials in a slider. You add them manually in WP admin. No collection form, no automation, no export. If you just need a quick way to display testimonials you already have and want the simplest possible setup, this works. But you'll outgrow it quickly.
Elfsight is embed-based like SocialProof, but specializes in pulling in reviews from Google, Yelp, Facebook, and other platforms. If you specifically want to display your existing Google reviews on your WordPress site, Elfsight is strong. The design quality is high. Main downside: the free tier is very limited, and pricing adds up across multiple widgets.
Some businesses build their own testimonial system using a form plugin. Customers submit via a form, responses go into WP or email, and you manually post them. This works and keeps everything in WP, but it's labor-intensive and fragile — you're the automation. Not recommended unless you already use these tools heavily.
| Option | Collects testimonials | Auto-displays | No plugin needed | Free tier |
|---|---|---|---|---|
| SocialProof | ✓ | ✓ | ✓ | ✓ |
| Strong Testimonials | ✓ | ✓ | ✗ | ✓ |
| WP Testimonials Slider | ✗ | ✓ | ✗ | ✓ |
| Elfsight | ✗ | ✓ | ✓ | Limited |
| DIY (WPForms) | ✓ | ✗ | ✗ | ✓ |
If you're using an embed-based solution like SocialProof, here's how to add it to your WordPress site:
For classic themes or widget areas, you can add the script to the footer via Appearance → Theme Editor → footer.php, or use a plugin like "Insert Headers and Footers" to add it cleanly without editing theme files.
The placement of testimonials matters as much as the testimonials themselves. Most businesses make the mistake of creating a dedicated /testimonials page and calling it done. Here's where they actually drive conversions:
A dedicated testimonials page is fine as a supporting page, but it should never be the only place testimonials live.
For most small businesses on WordPress:
The mistake to avoid: choosing a plugin based on features you'll never use. Most small businesses need to collect testimonials, display them beautifully, and move on. Keep it simple.
SocialProof works on WordPress without a plugin. Paste one line of code. Collect testimonials automatically. Display them beautifully — no setup required.
Try SocialProof free →No. Any embed-based testimonial tool (like SocialProof) works by pasting a script tag into a Custom HTML block — no plugin install required. WordPress plugins are optional, not mandatory, for adding testimonials.
Strong Testimonials has the best free tier among native WordPress plugins. If you're okay with an embed-based approach, SocialProof also has a free tier that works without a plugin.
It depends on implementation. Native plugins add database queries on every page load. Embed-based tools load asynchronously, so they have less impact on initial page load speed. Either way, the impact is usually small compared to image sizes, theme bloat, or hosting quality.
On WordPress.com's lower plans, you can't use custom JavaScript, which rules out embed-based tools. You need the Business plan ($25/mo) or above for custom scripts, or stick with a native WordPress.org plugin if you're self-hosting.
Elfsight is the best option specifically for pulling and displaying Google reviews on WordPress. Alternatively, you can screenshot your best Google reviews and add them as images, or ask customers who left Google reviews to also submit a direct testimonial through your website.
