Case Study: WWF Australia achieves 60% increase in web sessions and 72% growth in new visitors with Stackla

WWF Australia Creates Interactive Experiences for Earth Hour with User-Generated Content

WWF‑Australia used Earth Hour to mobilize supporters but faced a fragmented signup and content workflow: people registered via a basic form while photo submissions lived in a separate process, and the team needed a way to combine registration, direct image uploads and dynamic display on the site while integrating with backend systems like Marketo.

Stackla provided a next‑generation UGC solution that let supporters upload images directly on the Earth Hour site, synced registration data to Marketo, and powered a live social wall and a kids’ photo/letter contest. The campaign drove strong engagement — a 60% increase in web sessions year‑on‑year, 72% more new site visitors, roughly 150,000 social entries during the event, and double‑digit growth in social audiences (Twitter +17%, Instagram +32%).
