CASE STUDY: Rbia Shades completely transformed their online experience
After much success locally, Rbia needed a way to collect emails effectively on their brand-new website.
Their website provider did not have what they were looking for, so the search was on. After doing their research, they believed POWR was what they needed.
Rbia started to see success with POWR Popup almost immediately, adding over 600 new contacts in the first 90 days.
They then realized that there was a complete suite of other solutions they could use to improve their online experience for site visitors.
Soon, Rbia embedded an Instagram Feed app on their website and noticed site visitors who interacted with the app doubled the time spent on their page while growing their followers to over 11k on Insta at the same time.

Yes, POWR has an app for that.
