Conversion Rate Optimization (CRO) Expert for Custom HTML Site & A/B Testing

Upwork

We’re a high-traffic online business in the youth sports and education space. Our custom-coded HTML site (no CMS) supports a range of offerings, including event registrations, paid digital downloads, and lead generation through newsletter sign-ups and gated resources.

We’ve run a couple of A/B tests on a few pages, but need an experienced Conversion Rate Optimization (CRO) expert to take ownership of strategy, testing, and performance analysis. This is a long-term opportunity for someone who can move quickly, think strategically, and back their decisions with data.
