Chris Tested Pattern #9: Multiple Steps On Telestream.net

Pattern #9: Multiple Steps - Variant A
Pattern #9: Multiple Steps - Variant B

Telestream specializes in software that make it possible to get video content to any audience regardless of how it is created, distributed, or viewed. Telestream’s customer acquisition strategy is centered around driving traffic to their website to trial, or to purchase from their online store. Shoppers can buy software online, download it right away, and immediately start using it. The variation was designed with the same information as the control except spread across 4 steps (instead of 3). The rationale was that each step would be shorter and less overwhelming for the user.
