Website Element Customization is Next
Some may think only a 'techie' in the office or a self-proclaimed 'expert' on Facebook can expand a Testimonial Slider without a hitch.
Others look for low-cost alternative Testimonial Slider apps from overseas or open source Testimonial Slider apps that claim to have what they're looking for.

CASE STUDY: Rbia Shades is winning with POWR apps
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.
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.
