Reading Time: < 1 minuteStop listening to the customer. I know it sounds odd coming from a Conversion Optimization company, doesn’t it? But before you judge us – what if we probably have a good reason?

Reading Time: 7 minutesWe did a soft launch for FigPii in late January of this year. But we had a problem! Background: Our conversion optimization clients tend to be on the large side.

Clients would come in with horrible websites, outdated designs, and never had paid any attention to usability. You make a few fixes and test them against the control. And BAM! You have an amazing increase in conversions. For most websites, long gone are these […]
