CASE STUDY: Rbia Shades is winning with POWR apps
After Rbia launched its website, they were looking for a solution to add new contacts for outreach.
They found POWR while looking for a popup solution on their site and started to see immediate results.
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.

Yes, POWR has an app for that.
