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.

In just a few short months of installing a POWR Popup app, Rbia earned over 600 new contacts – a 250% growth.


Next, they used a Social Feed app and quickly noticed a leap in new followers on Instagram and 200% more engagement on their site.


Last came the Media Slider. A beautiful way to show off their products and accessories to every site visitor the moment they land on their site.
