*For balance let me just list the other tools I have used for session recording ; Tealeaf, Click tale and SessionCam.
With VWO, basically you tell it what page to watch and within minutes (not hours and days) you have a selection of user sessions to replay based on multiple devices and platforms. I was immediately hooked. No jerkiness, no blank screens, no style sheet dropping just a slick, smooth replay of the users every mouse move and click. I've already waxed lyrical about VWOs heat map tool, which integrates nicely with this tool. It's fairly addictive and I found myself replaying 24 sessions in one sitting!!
The payoff?
Having watched those sessions on a checkout page it became obvious we immediately had an issue. Every single visitor without exception was missing a credit card type field and missing the validation messages associated with this. So I fired up VWOs AB testing tool and created an alternative version of the checkout page with this card field in a more obvious place. Immediately we achieved a xx% improvement in sales performance.
Below are screenshots of the session replay in action. The red lines are the mouse moves. The blue bubbles are the left clicks.
