↑ Click visitor types to see matching in action
Most pricing pages show the same 3 testimonials to every visitor — regardless of why they're there or what's stopping them from signing up.
Someone who clicked a "$99/mo" ad needs to see that others got 10x return — not that your product is "easy to use."
Someone researching options wants credibility — logos, roles, specific outcomes — not a generic happy customer quote.
A VP of Sales needs to see that other VPs of Sales use your product — not a 5-person startup testimonial.
Paste a CSV of your existing testimonials. Proofer's tagging engine categorizes each one by outcome type — ROI, ease-of-use, trust, or enterprise credibility. Takes under 2 minutes.
CSV upload · auto-tagging · manual overrideCopy a single script tag onto your pricing page. No backend changes, no API keys, no engineering required. Works with any stack — Webflow, Framer, custom HTML, Next.js.

We had 14 testimonials and were showing the same 3 on rotation. Proofer matched the ROI ones to our paid ads traffic and we saw a measurable bump inside two weeks. Actual numbers, not vibes.
I was skeptical — I thought this was just testimonial reordering with an AI label on it. But the A/B test ran itself and the dashboard showed the lift clearly. I didn't have to trust anyone's opinion.
Setup took literally four minutes. I uploaded a CSV, copied the snippet, and the A/B test was running before lunch. The uplift showed up in the first 300 visitors.
The organic vs paid distinction was the insight I needed. Our Google traffic wasn't converting well — it turned out we were showing them the same testimonials as our retargeting audience.
Priced by visitors, not seats — because this is a growth lever, not a team tool.
