Why This Works
Social proof is one of the strongest conversion drivers in e-commerce, but most stores bury their reviews below the fold or rely on a generic star rating at the top of the page. A testimonial carousel placed right after the buy button puts real customer voices exactly where the purchase decision happens.
The key is making the testimonials specific to the product and targeted to your ICP. Generic five-star reviews don't move the needle. A review from someone who looks like your target customer, using language that matches how they think and talk about the product, builds real trust. It makes the shopper feel like "someone like me already bought this and loved it."
This is especially powerful for higher-consideration products where shoppers need that extra nudge of confidence before committing.
Best For
Stores with existing customer reviews they can pull from
Higher-consideration or premium-priced products
Products where trust and social proof matter (skincare, supplements, fashion, electronics)
Any store that doesn't currently surface testimonials prominently on the PDP
How to Set It Up
In your Elevate dashboard, click Page Experiment
Give your experiment a name (e.g. "Adding Testimonial to PDP") and add a description of your hypothesis
Set your primary metric to Revenue per Visitor
Select Product Page as the target. Choose the specific product(s) you want to run this on. Since the testimonial copy should be specific to the product, it's best to start with one product or a group of similar products rather than running it across your whole catalog
For the variation, click Add Custom Component. Select Testimonial Carousel from the list of Elevate components
Choose the placement. Elevate recommends after the buy button, which is a strong default since it appears right at the point of purchase decision. Hit Next
Select your primary template to duplicate, then click Duplicate. Elevate will create a copy prefixed with "eab"
Click Edit in Shopify to open the duplicated template in the theme editor
You'll see the testimonial carousel component already added. Click on it to customize. Elevate automatically pulls your brand colors so it blends with your theme, but you can adjust colors and styles if needed
Add your testimonials. For each one, add the review text, a customer photo, and their name. You can drag the component to reposition it on the page if you want it somewhere other than the default placement
Hit Save in the theme editor and go back to Elevate
Preview both the variation and control on desktop and mobile to make sure everything looks right
Leave traffic split at 50/50. No need to isolate traffic or set audience targeting for this test
Click Create Experiment to put it in preview state, do a final QA check, then Launch
Tips for Strong Testimonials
Use real reviews when possible. Pull from actual customer reviews you've received. The language will be more authentic and relatable because it's how your real customers actually talk about the product.
If you don't have reviews yet, you can use Claude to generate testimonials targeted to your ICP. Just make sure they sound natural and specific to the product, not generic.
Match the photos to your ICP. If you're selling sunglasses to women in their 30s, the testimonial photos should show women in their 30s. If it's a product for older men, show older men. The shopper needs to see someone who looks like them.
Be specific, not generic. "Great product, love it!" doesn't build trust. "These are my new everyday glasses, super lightweight and the UV protection is legit" does.
What to Look For
Primary metric: Revenue per visitor. This gives you the full-funnel picture of whether the added trust element is actually driving more purchases.
Also watch: Conversion rate and add-to-cart rate. A testimonial carousel is a trust element, so the biggest impact should show up in conversion rate (people who were on the fence now feeling confident enough to buy).
Timeline: 1-2 weeks for most stores. Since you're running this on specific products rather than your whole catalog, make sure the products you chose get enough traffic to reach significance.
