CASE STUDY: Rbia Shades completely transformed their online experience
Rbia Shades needed to expand beyond its region by bringing its products online. They needed a low-maintenance, non-techie solution.
After much research, they chose POWR as their no-code tool of choice.
Shortly after signing on with POWR, Rbia’s first step was to install a popup. They increased their contacts by over 250% (over 600 real contacts).
Soon after, they added our Social Feed app and grew their social media following to over 6000.
Next, they added a Media Slider as a visual way to quickly show their products to new site visitors as they entered their homepage to show how the accessories looked in real life. It showcases their products well and gave customers a great on-site experience.
In fact, they quickly found that visitors who interacted with POWR apps on their site stayed engaged 2.5 times longer than ever before.
