Stronger hero, more social proof on affiliate page: +17.66% sign-ups

WinnerSeveral changes tested togetherLanding page

A stronger hero, clearer copy and more social proof on a generic affiliate landing page lifted the sign-up rate by 17.66%.

Omnisend's in-house web growth team ran this A/B test, and it was published as a VWO case study.

Several changes shipped together, so no single element can claim the result.

+17.66% sign-ups
  • Sign-up rate: +17.66%, from 277 sign-ups out of 2,988 visitors (about 9.3%) to 318 out of 2,915 (about 10.9%).
  • Sample: about 5,900 visitors in total. Results were judged at a 90% confidence threshold.
  • Test duration was not shared.

Control

The generic affiliate landing page had a basic layout and little messaging.

Variant

The page got a more persuasive hero, refined copy, extra social proof and trust elements, plus updated widgets and redesigned sections.

Why it likely won

Our reading of the result, not the practitioner's claim.

  • Usability testing found unclear copy, a weak hero and too little social proof. The variant fixed all three.
  • The team believed the hero mattered most, thanks to clearer messaging and better focus.
  • Affiliate visitors arrive from someone else's recommendation, so proof that others use the product helps confirm that advice.
  • the gain came from several small fixes, so it is hard to say which one did the most.

Caveats: This was a bundled change, so the lift can't be credited to the hero or social proof alone. The sample was about 5,900 visitors and the test used a 90% confidence threshold, so the true lift may be smaller.

How to run this test on your site

Hypothesis
If we give our affiliate landing page a clearer hero and more social proof, then more referred visitors will sign up because they will quickly see what we offer and that others trust it.
Primary metric
Sign-up rate from affiliate traffic
Guardrails
  • Activation rate of new sign-ups
  • Bounce rate
  • Affiliate-attributed revenue
Who should test it
SaaS companies with partner or affiliate traffic landing on a thin, generic page. If your affiliate pages are already tailored and full of proof, expect a smaller gain.

Questions

What should an affiliate landing page include?

A clear hero that says what the product does, short copy, and social proof.

Omnisend lifted sign-ups 17.66% by adding all three.

Is social proof or the hero more important?

Omnisend's team thought the hero mattered most, but the changes shipped together.
