- Outcome: Won

- Elements: Social proof, authority & press, Testimonials

Adding social proof to a lead-gen landing page raised its conversion rate from 33.22% to 39.95%, and adding testimonials on top took it to 43.52%. KlientBoost ran this test for a lead-gen client and shared it on the KlientBoost blog. That works out to about a 31% relative lift for the version with both.

## Result

**33.22% to 43.52%**

- Version B (social proof): 39.95% vs 33.22%, about a 20% relative lift.
- Version C (social proof and testimonials): 43.52%, about a 31% relative lift over the original.
- Each step added more trust content, and each step converted better.
- No sample size, duration or significance figures were shared.

## Control

The original landing page had no social proof or testimonials.

## Variant

Version B added social proof to the page. Version C kept that social proof and added customer testimonials as well.

## Why it likely won (our reading)

- Lead forms ask visitors to hand over contact details, and proof that others trust the business lowers that risk.
- Testimonials add specific stories that general proof, like numbers or logos, can't give.
- Stacking two kinds of proof answers more doubts before the visitor reaches the form.

## Caveats

The client and industry were not named, and no sample size or significance was shared. Published on the KlientBoost blog around late 2017, so the data is older.

## How to run this test

- Hypothesis: If we add social proof and customer testimonials to our landing page, then form conversion rate will rise because visitors see that people like them already trust us.
- Primary metric: Landing page form conversion rate
- Guardrail: Lead quality
- Guardrail: Page load time
- Guardrail: Scroll depth to the form
- Who should test it: Lead-gen pages that currently show little or no proof. It fits newer or lesser-known brands best. If your page already has strong reviews and logos, adding more may do little.
