Social proof works best when it shows up exactly where a visitor hesitates. Adding it to a landing page is less about volume and more about placement and relevance.
This guide covers what to show, where to put it, and how to embed a curated proof wall in minutes.

We replaced three tools with this in a week. Onboarding was the smoothest I've seen in years.

Step 1 — Choose your strongest proof
Start with three to twelve pieces of proof that map to your visitor's objections: outcomes, named testimonials, recognizable logos, hard metrics.
- ✓Specific outcomes over generic praise
- ✓People who resemble your target buyer
- ✓A mix of testimonials, reviews and metrics
Step 2 — Place it where doubt peaks
Put proof near the moments of decision: just under the hero, beside the pricing, and right before the final call to action. A single curated wall can anchor the whole page.
Step 3 — Build the wall in Castio
Create a wall, add each proof point as a card, and approve the ones you want live. Pick a layout and theme that match the page.
Step 4 — Embed and measure
Publish the wall and paste the iframe snippet onto your landing page. Then watch wall views, card clicks and CTA clicks to learn which proof performs and double down.
