Case Study: ClickLab helps WriteWork increase purchases by 50% with VWO

Continuous A/B Testing Helped WriteWork Boost Number of Purchases

ClickLab, a Brazilian conversion rate optimization agency, used VWO Testing to help improve WriteWork.com’s primary landing page. The site relied heavily on organic traffic but had high bounce rates, and the team needed a way to better engage visitors and move them further down the funnel.

Using VWO, ClickLab segmented the A/B test to only landing-page visitors and tested a radical redesign that clarified the service’s benefits, added social proof, and strengthened credibility signals. The variation more than doubled engagement, increased clicks on the primary CTA by 144%, and a follow-up test showed purchases rose by over 50%—a strong result that ClickLab credited to VWO’s flexible testing setup.
