CASE STUDY: Rbia Shades wins big with POWR
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.
Rbia grew its contact list by 250% using POWR Popup to collect new email addresses from first-time site visitors.
They also added POWR Social Feed to their site and saw a 200% spike in engagement from their site visitors. They also saw a big jump in social media followers and now have over 11K followers on Instagram.

Yes, POWR has an app for that.
