CASE STUDY: Rbia Shades is winning with POWR apps

A few months after Rbia Shades launched at local fairs and craft shows, they were looking for a way to sell online.


They wanted to visually appeal to site visitors and demonstrate the quality of their product and lightweight, ergonomic designs.


Their web host did not provide an adequate solution for this, and after some research, decided to give POWR a try.

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.
